Statia celebrates World Environment Day
|
STENAPA staff, interns and volunteers complete a new set of steps on the Lower Tompi Hill Trail. |
This year, St Eustatius National Parks celebratedWorld Environment Day with a morning’s work on the Tompi Hill Head Trail, a popular trail next to the National Park Visitor Centre, and used by many people to reach Lower Town from White Wall road.
World Environment Day was established by the United Nations in 1972 to mark the opening of the Stockholm Conference on the Human Environment. Celebrated each year on 5th June, World Environment Day is one of the ways that the UN raises awareness of the environment and enhances political attention and action. The theme for 2009 is 'Your Planet Needs You-UNite to Combat Climate Change'. It reflects the urgency for nations to agree on a new deal at the crucial climate convention meeting in Copenhagen later this year, and the links with overcoming poverty and improved management of forests. To this end, the UN has partnered with many countries for the Billion Tree Campaign.
Four hours of intensive work on the Tompi Hill Head trail by a team of ten staff, interns and volunteers from STENAPA has made the trail much more accessible and ‘walker-friendly’. The team cut grass, built additional steps and cleared 5 bags of debris dropped by walkers as well as houses at the top of the cliff. All the bottles were taken to the glass crusher at Brown’s Garage. Finally, a 1 metre high July tree was planted at the lower entrance to Tompi Hill Head trail as a contribution the Billion Tree Campaign.

Green Water Event
|
New Volunteer group receives turtle training on Zeelandia Beach in preparation for nightly patrols. |
St. Eustatius-The Statia National Marine Park has initiated a research program investigating the effects a recent algal plume is having on the marine life in the waters surrounding Statia. The plume, which is a result of larger than usual outflow from the Orinoco River in South America, has been causing the waters surrounding Statia and the neighboring islands to turn green in the last six weeks, resulting in bad visibility for divers and possibly affecting coral reef health and fish catch. The plume was first noticed in early April and is now slowly starting to dissipate with the visibility improving in the last week or so.
The green coloration of the water is caused when nutrient rich fresh water from the South American continent mixes with salt water from the Caribbean Sea. This mixing produces algae which then supports an entire food chain of plankton, jellyfish, and fish. Because the mixed fresh and saltwater is lighter than the dense saltwater, the plume floats in the top 40 meters of the water column like a blanket.
Observation dives have revealed that below 40 meters the plume dissipates and the water is the usual clarity. Warmer than usual water temperature has also been recorded, possibly due to the plume; “We have been noticing warmer water temperature as a result of the algal plume and this has caused us some alarm. Because coral is susceptible to bleaching if the seawater temperature increases too much, and also because we have been receiving reports that the increased amount of nutrients in the water may be causing certain types of coral disease and affecting fishing in the area, we have decided to research the effects the plume might have,” commented Tadzio Bervoets, Marine Park Manager.
Research dives are being conducted by Marine Park staff using various research methods to gauge reef health and diversity. Fishermen were also questioned to see if they noticed a decrease in their fish catch during the event. Once all of the information is gathered and analyzed a report will be compiled and made available to the public.
Although conditions are improving, similar events are likely to increase in the future due to warming global temperatures brought on by climate change.

First Leatherback arrives early for 2009 nesting season!
|
New Volunteer group receives turtle training on Zeelandia Beach in preparation for nightly patrols. |
The first leatherback female of the season nested on Zeelandia beach in the early hours of 17th of March. She was observed by a local gentleman, Mr. Dennis Richardson, a member of the VKE. Mr. Richardson was able to provide Turtle Program staff with very useful information such as the exact location of her nest, her behaviour on the beach and the conditions on the beach. At the time that she was observed Mr. Richardson was on the beach taking part in an exercise with visiting Dutch Marines.
Marine Park staff were very happy to see the interest shown by Mr. Richardson, some members of the VKE and the Dutch marines on the following day when the nest was being marked. Staff members were happy to answer all the questions on sea turtles and their behaviour that were asked by the group.
Nightly beach patrols, which were due to begin as soon as the first turtle nested, have now started. The National Parks Foundation is happy to have the help of Mr. Micah Herriot, who will be working as the turtle program intern for this year. Mr. Herriot who hails from Canada will be doing most of the field work and will be assisting Ms. Jessica Berkel who has taken over the role of Turtle Program coordinator.
The timing of the arrival of the nesting female could not have been more fortunate as a new group of volunteers have arrived and will be a great help in assisting with the nightly patrols. The female left a very nice track in the sand on the very day that the group were to go down on the beach for their turtle training. It was nice to have a fresh track for them to observe so that they know exactly what to look for during nightly patrols.
The program coordinator would like to remind the general public that it is a violation of the law to, in any way, disturb nesting females and their nesting beaches. Loud noises, bright lights, bonfires and driving on the beach are strongly discouraged and the public is kindly asked for their cooperation. Sand mining remains one of the largest threats to the successful hatching of the nests.
STENAPA’s monthly radio program “Nature on Statia” which will air on Thursday, April 2nd at 10:30am (and again at 2:30pm) will focus on the turtle program and provide listeners with much more information.
Members of the public are welcome to pay us a visit and learn more about what they can do to assist the 2009 Turtle Program.

Say ‘no’ to plastics on Statia
St Eustatius National Parks is very proud to acknowledge the work and contributions of all the shops on Statia to continue the anti-plastics campaign started by STENAPA and the Government in 2004. The initial stock of 3000 ‘eco-bags’ with the distinctive logo artwork of Benjamin Boyce (Lynch Plantation School) was funded by MINA in 2004. About 2000 bags were distributed freely (two to every household and one to every school student) and the stock finally sold out this month due to the fact that over 10 shops have been selling the bags and encouraging their customers not to use plastics since early last year. STENAPA will soon start distributing a more environmentally friendly ‘eco-bag’ – made from reused plastic bags in a distinctive green colour.
We thank the shops that took their own initiative to either stop providing plastic bags or that went further to stock biodegradable plastic bags for sale, such as Mazinga Gift Shop.
More recently, the project ‘A Clean, Beautiful and Safe Statia’, led by Winston Fleming, has appealed further to shops to stop distributing plastic bags, and it is rewarding to see many shops now banning plastic bags. We look forward to more activities to clean up Statia further – let’s start tackling Styrofoam!
And recycling has finally arrived. Residents are now asked to save their glass (beer bottles, jars, other containers) and deliver them to a dedicated container (to be installed soon) at Brown’s Garage where Lennard Brown is installing a glass crusher. If you are unable to deliver your bottles, please call Lennard on 318 1107 and he will collect your glass. The glass crushing machine will produce glass that can be used in concrete mix, asphalt and as decoration for walls – and is an environmentally-friendly alternative to sand.
Children appalled- Dead Shark in Harbour!
(February 23 2009)
|

On the afternoon of the 16th of February, Marine Park staff was alerted at the Blue pier about a Shark that was rolling around beneath the waves. The animal was discovered by local children during a routine snorkel club activity held by the Marine Park. One of the children said “I could not believe the poor shark was dead” and another was sad that “I wish I could have seen it swim about”.
The Marine Park Manager, Lee Munson, raced to the scene and immediately tried to swim the animal forcing water and oxygen over the gills. After 15 minutes it was pronounced dead and pulled from the sea. After a brief anatomy lesson of the small female, the Park Manager and children released the animal outside of the Marine Park.
On return from the release, Ingrid Walther from Scubaqua informed the Marine Park how she and her guests witnessed a harbour worker tossing the Juvenile Nurse Shark into the water in the harbour area. She could not believe her eyes especially when her dive guests travel up to 8,000km to see sharks ALIVE. This kind of behaviour can have serious effects on dive tourism which brings in large revenues to the island.
Humankind is responsible for the death of 200 million sharks per year just for fin fishing in Asia, with 20% of all species on the brink of extinction. Sharks have been swimming the world’s oceans for over 400 million years. Sharks are slow growing, long lived animals that have very few young. This makes them highly vulnerable to over fishing and eventually localised extinction.
We are very fortunate to still have a small population of sharks around St Eustatius and should consider their economic and ecological importance. Sharks have an important ecological role and prey upon old, sick or injured fish which, in turn, prevents disease from spreading. This keeps our reefs healthy and diverse.
We should all try and do our best to help the nature on Statia for the future benefit of the island. STENAPA welcomes any member of the public to come and pay us a visit and learn more about what you can do to help conserve the wildlife of the island. [go up]
New Statia National Marine Park Patrol Boat Blue Runner
(January 20 2009)
On Wednesday, January 14th, the new Marine Park Patrol boat for the St. Eustatius National Parks Foundation arrived in Statia’s harbour. The new boat is a Privateer Renegade 2400 and has been manufactured to the specifications provided by STENAPA. The boat was ordered after consultation with the Saba Conservation Foundation (SCF) who purchased a similar boat last year. Since Saba Marine Park has similar needs to us and operates under the same water conditions, it was decided that we would go with the same type of vessel.
The purchase of this patrol boat was long overdue as the current patrol boat, Success, is well over 10 years old. In the past year, the maintenance of the Success had been taking up more and more of the rangers’ time, and the boat was in urgent need of replacement.
This new patrol boat has many improvements over the Success, such as two powerful fuel efficient four stroke engines which means more power and reduced emissions, a V-shape hull, a shade canopy and chair for the Captain, more storage and work space and a dive ladder, among other things.
The name of the boat Blue Runner was selected by a contest during STENAPA anniversary celebration week. Staff members, board members, visitors to the Visitor Centre, Snorkel club and Junior Ranger members all sent in entries for possible boat names. The ultimate winner was the name “Blue Runner” which was proposed by staff member, Jessica Berkel, and received the most votes overall.
At 2.30pm on 20th January, the boat was blessed, officially christened and toasted with champagne by Former Harbour Master Mervin Gittens. Present were Acting Harbour Master Austin van Heynigen, STENAPA President, Irving Brown and STENAPA Secretary Ingrid Walther as well as other Board members, Friends of STENAPA, staff, interns and volunteers. All present were treated to a tour around the bay for Blue Runner’s maiden voyage.
It has taken several years to raise funds to purchase this new boat and STENAPA is extremely grateful for a generous grant from Stichting DOEN in the Netherlands, in order to purchase the boat amongst other projects. [go up]
Quill/Boven National Park and Botanical Garden management plan complete
(January 16 2009)
|
Mr. Irving Brown accepts the management report from Mr. Duncan MacRae. |
The board and management of the St. Eustatius National Parks Foundation (STENAPA) are pleased to announce the completion of the Quill/Boven National Park and Botanical Garden Management plan. This management plan is a five year plan that outlines the park information available, goals expressed by stakeholders for the National Park to address, and the strategy that will be employed to achieve those goals within that timeframe.
Work on the management plan began late 2007 when Mr Jan Blok – a forestry ecologist from Staatsbosbeheer in the Netherlands and author of the first National Park management plan– visited the National Parks and had initial meetings with major stakeholders. Work focused on stakeholders early in 2008 with the visit of Ms. Yvonne Hosker who held interviews, visited schools and talked to residents and visitors to the island. Additionally, stakeholder consultations and an island wide survey were held, including radio and TV phone-in programmes. Throughout the year there was continued collection of data concerning the National Park such as history, biodiversity and legislation covering the areas. Questionnaires were also filled out by persons returning from their hike on the Quill in order to gauge their opinions on the trail network.
Mr. Duncan MacRae, Executive Director of the company Coastal Zone Management, based in the U.K., was responsible for final production of the Quill/Boven National Park and Botanical Garden management plan, arranging an external review by National Park experts, and presented it to Mr. Irving Brown, President of the Board of the National Parks Foundation at the National Park Visitor Centre on 15th January 2009.
Mr. MacRae is also busy with management plans for the other parks in the Windward and Leeward Islands, and has already completed Marine Park management plans for Bonaire, St Maarten and St Eustatius. His work is being funded by the Dutch Caribbean Nature Alliance (DCNA). These management plans are usually a requirement by Island Governments for all terrestrial and Marine Parks in the Windward Islands. [go up]
10 years Quill/Boven National Park -
20 years anniversary of STENAPA
(December 12 2008)
This year has been a major milestone for STENAPA and for the Quill / Boven National Park in St Eustatius.
It has been 20 years since STENAPA was established by four visionary Statians (Ellis Lopes, Mevrille Hazel, Sheila Cecilia-Marsdin and the deceased Miriam Schmidt). These founding members had a love of nature and concern about increasing development on Statia. They had a vision for National Parks and a Botanical Garden years before the parks were created.
Established in 1988, STENAPA is the only organisation on Statia with a directive for nature conservation and environmental protection, and is legally mandated by the Island Government to manage all the island’s protected areas (St Eustatius National Marine Park, the Quill/Boven National Park as well as the young Botanical Garden). Collectively, the protected areas account for 33km² of land and sea and encompass many different endangered ecosystems – from elfin forest and montane thicket all the way down to coral reef and sea grass. Over the years, projects have grown in size and impact and recently, the largest project has been the reconstruction and transformation of the National Park headquarters, at Gallows Bay, and members of the public are welcome during office hours on weekdays to visit our displays and learn more about activities.
It has also been 10 years since the Island Government of St Eustatius requested STENAPA to manage the newly created Quill / Boven National Park. The National Park was established to protect the unique characteristics of the Quill dormant volcano, and also the Boven extinct volcano with surrounding hills. The park protects all the animals and plants, as well as historical artefacts within its boundaries, which include the endemic Statia Morning Glory – a plant that only grows in Statia and no where else – many species of orchids, the endangered Antillean Iguana, Red Bellied Racer snake – that is only found on Statia and Saba – and much more. The main objectives for the park include enabling access for the general public, general protection of fauna and flora, and gaining information for proper management of the park. Our activities within the park are construction and maintenance of signposted trails, guided hikes for groups and individuals, research and monitoring about the plants and animals living in the park, and lastly patrols to enforce the park regulations. We are proud to mark this anniversary with the announcement that the new Quill / Boven National Park and Botanical Garden management plan is ready after a year of consultations with about 250 stakeholders, and it will be distributed to key stakeholders shortly. A guidebook about the National Park will also be launched early next year.
Many events have been held in the past weeks to celebrate this important milestone, commencing with a nature photo contest and treasure hunt. Many people have joined us on four guided hikes. The Statia Park Splash welcomed over 100 children to enjoy a variety of nature-related games and activities (face paints, splashing the frog, pinning the iguana on the silk cotton tree, colouring-in nature pictures, National Park treasure map, and more). Past and present Board members attended a picnic at the Botanical Garden and festivities culminated on Friday 12th with a party with BBQ and presentation of prizes for treasure hunt entries and winning photos from over 100 entries. STENAPA gratefully acknowledges the funding from Stichting Doen of the Netherlands for these festivities.
If your interest about the national parks has been raised, and you wish to learn more about the park and join us for a guided hike, come along this weekend for a hike on Gilboa Hill (meeting at 8am Saturday and Sunday at end of Zeelandia Road), or contact the National Park Visitor Centre to arrange a hike in the coming months.

Initial Reef Assessment and clean up after Omar
(October 16 2008)
|
STENAPA volunteers returning from a cleanup drive |
On October 16th, 2008, Hurricane Omar developed in the Caribbean basin and followed a North Easterly trajectory toward the windward islands. Luckily for the island of St Eustatius the core of the hurricane moved further North toward the British Virgin Islands. This storm produced huge swells that pounded the west coast of Statia and heavy rains washed huge amounts of sediment into the ocean. It appeared that there was a huge amount of underwater movement of sea grass and rubbish materials that aggregated around some of our most prized dive/ fishing sites in the vicinity of the Harbor.
Reef clean ups were carried out at 5 dive sites by staff of the St. Eustatius National Parks Foundation (STENAPA) assisted by volunteers. These sites were located in and around the harbor area and included the Charles Brown, Chien Tong, STENAPA reef, Double Wreck and Triple Wreck. These sites seemed to have accumulated most of the garbage materials and sea grass that became loose and mobile during the storm. The location which appeared to suffer most was Double Wreck.

Jessica Berkel collecting tins and plastic bottles |
A total of 26 individual dives have been carried out by STENAPA so far with an estimated 4 more to come. Approximately one 10 Gallon refuge sack of cans and plastic containers were picked up on every dive with some larger plastics also surfaced. Two mangled fish traps were recovered from Double wreck. The Marine Park Manager took part in cleaning all the affected sites and was able to make a rapid assessment of the sites affected. Heavy sponge loss was apparent at Double and Triple Wreck due in large part to the swells and movement of large quantities of sea grass. Fish populations are still intact at all the sites and coral loss is yet to be estimated. The Chien Tong and Charles Brown are both intact but have been shaken up a little. Strict caution is advised for anyone planning to venture inside of these wrecks. The sea grass beds surrounding Double/Triple wreck and STENAPA reef have been disturbed and covered in sand, these sites are also heavily surrounded by dislodged sea grass and broken sponges. This will inevitably have a knock on effect for Green sea turtles (Chelonia midas) encounters as they mainly feed on the grass in these areas. The Marine Park was happy to have removed large quantities of clear plastic that had broken away from under the deck of the Chien Tong (see photo). This plastic is of great concern to us as it resembles a treat food for our sea turtle populations, the jellyfish. Once ingested this material clogs up the gut and prevents the animal from eating further and will usually result in death. It is a great reminder that we need to be more aware of where plastic can end up especially on a small island and what we can do to limit the use of plastics.
The Marine Park will conduct a benthic assessment over the coming weeks to assess more accurately the effects Omar has had on the sessile organisms such as corals and sponges. At a glance, the reef in the Southern Reserve has not been significantly affected. Only in the 15-10m zone was there any signs of coral (mostly gorgonians) and sponge damage and this was only minor. Statia is fortunate to have such a large reef extending far from the shore with only very small beaches on the west coast. This reduces any smothering damage that may come about from sand movement and or run off on to the most productive areas of reef (10-30m zone). Storms and hurricanes have been happening throughout history and are not necessarily a bad thing. Over time the reef can get heavily populated with fewer more dominating species and thus reducing diversity. With the loss of some of these organisms come fresh opportunities for settlement and growth of new life on the reef.
The Marine Park coordinated a massive beach clean up targeted at Zeelandia through to Turtle beach (our index sea turtle nesting beach). On the morning of 7th November, 4 staff were joined by 9 volunteers to conduct the clean up. They successfully removed 3 truck loads of rubbish, mainly of plastic origin that had probably run down from the dump site. Other items removed include an oil drum, gas bottle, fishing net, plastic waste bin, many shoes and glass bottles.
As a result of finding so much plastic washed to the sea, we would like to remind everyone of the importance of maintaining a healthy island environment, and urge people to think twice about the amount of plastics used. [go up]
Junior Ranger Graduates
(June 12 2008)
On Thursday June 12, 2008 nine students graduated from STENAPA’s Junior Ranger 1 and 2 programmes. The programmes had been running every week since September 2007, informing students about what STENAPA does, general environmental issues and the importance of protecting nature on their island.
The students that graduated are: Francesca Dembrook, Kendro Redan, Luceta van Putten, Bradley van Putten, Jeremiah Malone, Martijn de Jong, Revinio Schmidt, Matthijs de Bruin and Alleandré Hook. Each student received a certificate of participation and a CD with all the photos taken throughout the year. All the students showed enthusiasm during the programme, but four students won prizes for their particular hard work and commitment to Junior Rangers. Matthijs de Bruin and Martijn de Jong each won PADI Open Water certifications and Ali Hook won an Advanced Open Water certification, courtesy of Dive Statia and Scubaqua. Revinio Schmidt, grandson of Miriam C. Schmidt, won free entry to Junior Rangers 2 as well as a fascinating book by Suzanne Nielsen on the medicinal plants of Saba, many of which are also found on Statia.
During the year the students participated in many activities, held at the Botanical Garden, in the Marine Park and other locations around Statia. They learned about Statia’s plant, terrestrial and marine life, did beach cleanups at Venus Bay and Corre Corre, snorkelled, learned about hurricanes and volcanoes, hiked the Quill and Boven, learned how to maintain the hiking trails and much more. At the end of the programme they were treated to a boat ride around Statia and a small party at the Botanical Garden. STENAPA hopes that the JR1 students will return for JR2, and that all students will return as interns when they reach the appropriate age. The aim is to encourage these children to remain interested in nature conservation and to eventually become STENAPA rangers or managers in the future.
Junior Rangers 1 and 2 will start again in September to coincide with the school year. Any students interested in joining are welcome to visit the National Parks office for more information. For those who cannot wait, however, STENAPA’s Summer Club begins on Monday June 30, offering activities in the Botanical Garden as well as hiking, snorkelling and turtle education. [go up]
Orchid experts visit Statia
(June 12 2008)
|
Drs Ackerman and Tremblay together with Hannah Leslie and Lindsay Galway at Mazinga Peak |
St. Eustatius National Parks this week received a visit from orchid expert Dr. James Ackerman and population dynamics expert Dr. Raymond Tremblay, both from the University of Puerto Rico. They visited Statia in order to assist STENAPA with an inventory of the orchids of the island and to establish a monitoring program to ensure the conservation of Statia’s orchid species. They spent three full days out in the field with National Park Ranger Hannah Leslie and intern Lindsay Galway.
Statia is home to about 14 species of orchid, some of which have not been seen for some time. Brassavola cucullata is just one of the magnificent specimens found on the island. The island has several more species than others of similar size such as St. Barths, St. Maarten, Nevis and Saba, and more than a number of much larger islands as well. The diversity of habitats found on Statia is key to the relatively high number of species found. The hot, relatively dry conditions found on Boven harbour some species not seen elsewhere, and conversely the moist lush forests on the upper elevations of the Quill are occupied by other species. With the advent of the Boven and Quill National Parks, the orchids have a home where they have the potential to thrive for the enjoyment of all.
Orchids on Statia and elsewhere exist because of a web of relationships with other organisms. An orchid seed cannot germinate without being infected by a fungus (which the orchid then parasitizes!), and orchids usually cannot produce seeds without bees, birds, butterflies, wasps, or moths to pollinate the flowers. Each species has one or few types of pollinators, and in the case of Brassavola cucullata, the pollinator is likely to be a long-tongued moth that probes the depths of the flower searching for nectar. The flower emits a heavy sweet perfume at night to attract the moth. The orchid, though, offers nothing for the services of the moth. The orchid’s partners for survival are not partners after all. The orchid takes advantage of the fungus and dupes the pollinator. As Brassavola cucullata shows, Statia should be recognized not only for its remarkable marine life, but also for its fascinating plant life.
STENAPA will continue its orchid study on Statia and is keen to set up a long-term research project in collaboration with the University of Puerto Rico. The organization also looks forward to welcoming Jim and Raymond back to Statia in early 2009 so that they can document the terrestrial orchids which bloom at that time. [go up]
New species of beetle discovered in Statia
(June 4 2008)
|
Article in the local newspaper |
Very little information is known about the diversity and numbers of fauna and flora of St Eustatius, and much of the current information is based on scientific work carried out pre-1970. In the past five years, St Eustatius National Parks has been working with a number of scientists to increase knowledge about nature on Statia, and within the National Parks. An island wide plant inventory commenced in January this year, followed by further research in March when there were new records of a terrestrial orchid (Mesadenus lucayanus) as well as mistletoe (Phoradendron trinervium).
Existing records (dating as early as 1937) report only four families and 11 species of beetles in St Eustatius. During a rapid inventory of beetle diversity in the Quill/Boven National Park on 26-27 May 2008, around 1000 specimens were collected by entomologist Dr Michael Ivie from Montana State University. Dr Ivie has now contacted St Eustatius National Parks to confirm that he has added records for 13 new families of beetles. At the species level, Dr Ivie confirmed that the known number of species of beetles has at least quadrupled, with further examination of the specimens required to complete the documentation. The large increase in number of species recorded in just two days of fieldwork points toward a very much larger number of beetles in St Eustatius, and Dr Ivie is planning to return to St Eustatius for a more detailed inventory.
Whilst there is understandably very little interest in beetles, insects are undeniably critical to the terrestrial eco-system on St Eustatius, as they are a food source for animals higher up the food chain, and also speed up decomposition of dead animals and plants. [go up]
Board elections St. Eustatius National Parks Foundation (STENAPA)
(March 8 2008)
The board of the St. Eustatius National Parks Foundation (STENAPA) held their biannual elections during the April board meeting. Congratulations are in order for Ms. Ruth Pandt who was elected Treasurer and Mrs. Ingrid Walther, elected Secretary of the organization. Ruth Pandt, who represents the Beautification Committee, now takes over the Treasurer position from Ms. Jana Mason who had held the position for two consecutive terms. Statutes prevent a member from exceeding two terms in an elected position.
Mrs. Walther, part owner of the Scubaqua dive centre and fulfilling the position of dive shop representative on the board, now fills the position of secretary which had been vacant for some two years.
There is no change in the positions of the remaining two elected officers, Mr. Irving Brown (President) and Mr. Ronald Courtar (Vice-President). Beside the four elected members there are five ordinary members who are Ms. Pamela Berkel (representing Statia PRIDE), Ms. Kay Boyd, Ms. Jana Mason, Mr. Daniel Eaton and Mr. Ira Walker.
The board of the National Parks Foundation would like to remind the general public that anyone who is interested in becoming a member should submit a letter of interest to the National Park Visitor Centre. Board meetings are generally held on the evening of the first Tuesday of every month. [go up]
New orchid discovered during botany course on Statia
(March 8 2008)
|
Dancing Dolls orchid (Tolumnia urophylla) by ASJ van Proosdij |
During the past two weeks, St Eustatius National Parks (STENAPA) has been fortunate to receive a training course from botanist André van Proosdij from the Hortus Botanicus of Amsterdam. Van Proosdij was born on Curaçao, has worked with CARMABI and is author of the Zakflora of Aruba, Bonaire and Curaçao. Asked about the plants of Statia, he explained that ‘behind every rock, and every corner, there is something new to discover’.
The team of rangers and other staff members visited a number of different areas of Statia, including the rich vegetation zones of the Quill and Boven National Park. Some of the striking discoveries of last week include four new patches of Statia Morning Glory (Ipomoea sphenophylla) on the eastern slopes of Bergje in the Boven National Park, a plant of Mistletoe (Phoradendron trinervium) as well as many new records of orchids (both terrestrial and epiphytic) in both the Quill and Boven National Park.
The most exciting discovery was the first record of a terrestrial orchid in the Boven National Park.
The orchid was almost hidden on a very inaccessible rocky slope and spotted by team. This orchid species, Mesadenus lucayanus is a new record for St Eustatius. This orchid is found on the islands of BVI and Antigua. New areas of the Dancing Dolls orchid (Tolumnia urophylla were also found in the Quill (above White Wall) National Park. Following these discoveries, Ranger Hannah Leslie will study and map orchid distribution more closely on Statia.
The team of Park Rangers had already participated in the plant survey by the New York Botanical Garden in February this year. After these weeks of intensive training, the local team is now well trained and able to continue the survey of flora of Statia. [go up]
Bonaire National Marine Park rangers visit Statia
(March 2008)

During the past two weeks, a team of three rangers from Bonaire National Marine Park have been working closely with rangers in Statia National Marine Park. The visit was organised as the second stage of a ranger exchange scheme between STINAPA Bonaire and STENAPA through a programme to increase capacity of park rangers and funded by the Dutch Caribbean Nature Alliance (DCNA). Three staff from STENAPA had already worked with rangers in Bonaire in April 2006.
The Bonaire rangers completed all the routine daily tasks of the Marine Park, including mooring maintenance, patrols, yacht fee collection, diver supervision and fee checks, turtle in-water monitoring dives, Zeelandia beach clean-up, patrol boat and dinghy maintenance, and snorkel club instruction for 8-10 year olds. They also worked hard with Statia rangers, Walter Blair and Nadio Spanner to install four new yacht moorings using manta rays in Oranjestad Bay.
Upon their departure, the rangers said that they had learned a great deal in Statia and that they had found that the people were very friendly and gentle – much more friendly than in Bonaire. The Chief Ranger urged the Island Government that if they want to keep the coral in good health, they need to put down more laws, such as banning spear fishing (especially those working with tourists) and also ensuring that there was more personnel working for the Marine Park.

Project to develop Fruit and Children’s Garden at Botanical Garden
(January 2008)
A project of approximately 49,000 guilders has been awarded to STENAPA to provide supplies and equipment enabling the creation of a Children’s Garden and the Fruit Garden in the Miriam C. Schmidt Botanical Garden. The grant was awarded by USONA via the Department of Environment and Nature (MINA) in late 2007.
The project activities focus on Phase 2 of the Botanical Garden. A public pavilion will be constructed at the top of the Children’s Garden as a centre for school and group activities and equipped with solar panels, cistern, and picnic tables. The solar panels are an environmentally friendly option for the pavilion, making it electrically self-sufficient. In addition, visitors will be able to use the area to picnic or rest in the shade. Although this pavilion will be centered in the Children’s Garden, it will also benefit the Fruit Garden by collecting rainwater and providing water for the Fruit Garden.
The Children’s Garden is situated on a fairly steeply sloping hillside. Project activities have already commenced to landscape this garden area with a bulldozer to grade and form several different activity areas, including a playground area with swings, a playhouse, and a climbing frame. In addition, the grant provides funds for rubber ground covering made out of recycled tires to make the area safer for children playing.
Currently, there are only several fruit trees in the Fruit Garden that have been grown from cuttings from local trees. This project provides much needed funds to obtain and plant a wider diversity of fruit trees. The funds specifically for the Fruit Garden include fruit trees, potting soil, plant books, markers, and information boards for visitors. At the moment, the fruit garden is being cleared of Corallita to make room for the new fruit trees.
Progress has been underway at both the Children’s Garden and the Fruit Garden since early 2007, mostly through clearing Corallita and creating garden areas within natural vegetation. Information signs for both gardens are currently being designed and printed so that they will be in place in the next months. All supplies and equipment should be on island in time to officially open the Children’s Garden by mid 2008, and the Fruit Garden a little later.
Even though these gardens are not yet completed, the Miriam C. Schmidt Botanical Gardens are open seven days a week from sunup to sundown. Visitors are welcome to check out the established gardens as well as our current progress. [go up]
New staf member joins STENAPA
|
Lee Munson
is the new National Marine Park manager. |
We would like to announce that STENAPA has a new staff
member, Lee Munson has joined as Manager of Statia National
Marine Park. This is a new position merging roles from
two previous posts of Assistant Manager and Sea Turtle
Coordinator.
Lee is originally from Exeter, UK and spent his teenage
years in Spain. In 2001, he graduated with a BSc (Hons)
in Marine Biology, specializing in Coastal Ecology.
With a passion for conserving the marine environment
and an interest in protected area management, Lee has
since travelled, volunteered and worked around the globe.
Lee gained his dive instructor certification in 2004.
In April 2004, Lee joined Global Vision International
working on the Meso-American Barrier Reef System (MBRS)
monitoring program in Mahahual, Mexico. His role was
diverse including; dive (PADI) and reef survey, tuition
for volunteers, boat handling, equipment maintenance,
data and base management.
In 2005, Lee started his own company in Sweden, offering
dive and marine ecological services on a small scale.
He was contracted in by the Naturhistoriska riksmuseet
in Stockholm in order to survey, collect and identify
the marine fish of Los Cobanos, El Salvador. This, the
first scientific marine survey of the area was written
up as a report (in publication) on the biodiversity
present with recommendations for management that will
assist in the development of a marine reserve. This
work highlighted the importance of involving NGOs, dive
centres, fishermen, local communities, universities,
local government and other stakeholders in conservation
efforts.
From 2006-2007, Lee travelled in Africa and worked at
two Mozambican Eco-Lodges. His responsibilities as dive
manager and marine biologist at Guludo Beach lodge were
varied allowing him to gain extensive experience in
dive centre management including the servicing and maintenance
of all the equipment (compressor, boats, SCUBA equipment),
refining the local dive team (protocols) and dive safety.
Whilst diving at the Lodge, he managed to gather valuable
data (coral health, indicator specie abundance, turtle
and shark population data and abiotics). The most exciting
monitoring program was the humpback whale project. With
funding from Eco tourism, the team was able to record
behaviour and photo identify passing whales for the
South African Population Database, as well as raise
public awareness and aid conservation. [go

Annual reef monitoring of St Eustatius National Marine
Park
|
Reef checks
provide information on the health status of coral
reefs. |
St Eustatius National Marine Park completed their third annual
monitoring survey of the reef this month. Using the
Reef Check survey protocol, a total of 16 survey dives
took place to assess numbers of fish, invertebrates
and reef substrate at Barracuda Reef and Mushroom Garden
in the Southern Reserve. The surveys are conducted by
laying down a 100m transect line starting at the mooring
line. The divers then swim along this line recording
numbers and species of fish and invertebrates, as well
as the substrate directly below the line. The data collection
is done on two separate occasions for a better-rounded
representation of the reef’s health.
Reef Check is the largest international coral monitoring
and conservation programme that commenced in 1996 when
1107 sites were accepted for study. The data help scientists
evaluate the health of reefs and their ecosystems on
a global scale. An example of the information gained
is “the 1997-98 coral bleaching event reduced
live coral cover by 10% globally, indicating that coral
reefs are a sensitive indicator of global warming,”
(2004 Reef Check Instruction Manual).
Similar to all neighbouring islands, St Eustatius experienced
an incident of coral bleaching during August-October
2005 when sea water temperature exceeded 30¾C over two
months. Data for 2005 and 2007 show that deeper site,
Barracuda Reef, was more broadly impacted by the bleaching
with a large decrease in live substrate (from 99% to
57%). The reef at Mushroom Garden was less impacted
(live substrate cover declining from 873% to 73%). In
addition to impacts from coral bleaching, some variation
in substrate cover may also be attributed to the fact
that the transect line is not permanent.
Fish populations at both sites are healthy, and, despite
the change in reef due to bleaching, both sites had
higher numbers of fish in 2007. The most abundant fish
species at the shallower site, Mushroom Gardens were
parrotfish. The most common fish were Haemulidae (grunts
and margates), parrotfish and groupers at Barracuda
Reef. The large increase in numbers of grouper has been
particularly notable; this fish family is easily fished
out and was rarely seen when the Marine Park opened
in 1997.
Another sign of the protected status of these reefs
is the abundance of soft corals. Gorgonians or sea fans
(as shown in picture) are the most common coral found
at these sites and there was an amazing total of 212
counted during the survey at Mushroom Gardens.
One way to track recovery of a reef from bleaching is
through the amount of nutrient indicator algae. High
algal cover can negatively impact on the repair and
revival of hard corals after a harmful incident such
as coral bleaching. Both survey sites currently have
approximately 25% cover by nutrient indicator algae.
As the algae is relatively dispersed, it is hoped that
hard coral cover at both reefs will continue to recover
in 2008. A more detailed report is available on www.statiapark.org. [go up]

“Track” Trucking to the Virgin
Islands.
|
Green turtle
'Track' equipped with satellite transmitter. |
A week after Track has been equipped with a satellite
transmitter, signals are coming in from the Virgin Islands
and even north of Puerto Rico. Track has covered over
380 kilometers in as little as seven days, averaging
76 kilometers to her feeding grounds.
After nesting attempts on Zeelandia beach Track is now
migrating to her feeding grounds. Her total distance
traveled since she has was equipped with her satellite
transmitter is 762 Km.
The DCNA turtle tracking programme is a collaborative
effort between St Eustatius National Parks (STENAPA)
and the Nature Foundation St Maarten. Its objectives
are to collect migration information on hard shell (Hawksbill,
Green) species of sea turtles within the Eastern Caribbean.
Up to date information on Track’s whereabouts
can be found here [go up]
Tracking “Track”
|
Current
location of 'Track'. |
The last of the five turtle tracking satellites allocated
to St Eustatius (STENAPA) and St. Maarten (NFSXM) was
used on Zeelandia Beach at 11:27 P.M. on Saturday the
first of September. This Green turtle has been recorded
on Statia for the last five years and has already come
up to nest four times during the 2007 season. She was
previously recorded in 2002 and in 2005. The Turtle,
named “Track”, attempted to nest but found
the area she chose to be too rocky. The satellite transmitter
was activated at 12:11 A.M. on the 2nd as the work to
attach the transmitter began. After all the work was
completed, fiberglass dried and tested, she was released
back into the ocean by 3:20 A.M. on the 2nd.
“Track” is an average sized green turtle,
1.12 meters in length and 1.07 meters wide. She was
previously tagged by STENAPA. The satellite will give
detailed information that could have never been collected
without the contribution of DCNA (Dutch Caribbean Nature
Alliance). Track is using Zeelandia Beach as her home
base for the nesting phase of her life. This makes the
data being collected more valuable to see what waters
she frequents for other periods of the year.
All STENAPA volunteers and interns, along with the Marine
Turtle Coordinator as well as several local residents
were present for this event. Up to date information
on Track’s whereabouts can be found here
Satellite Transmission of two turtles terminated
The journeys of Lisa and Grace, two turtles found on
Zeelandia beach and fitted with satellite tracking systems
in September, have come to an end. Lisa, a hawksbill
turtle, was fitted with a satellite transmitter on Zeelandia
beach on September 8th 2006, while Grace, the green
turtle, was fitted with a transmitter ten days later,
on September 18th. The two turtles were both satellite
tagged in St Eustatius on Zeelandia Beach. The battery
used for the tracking systems has an estimated life
of six months under ideal conditions.
Lisa was the first hawksbill of her species nesting
on Statia for the season. She laid 143 eggs and has
an average carapace length of 85.5 cm. Her name was
chosen by Evan Hassel, a 4th grade student at the Governor
de Graaf School, who was one of the winners of an art
and craft competition held in 2005. Lisa’s last
transmission was made on February 1st 2007 after she
had travelled 2870 kilometres with the tracking device.
The foraging habits of hawksbills tend to deteriorate
the satellite devices faster than other turtles. This
is mainly due to the fact that they manoeuvre themselves
into crevices to feed on their favourite meal of sponges.
The loss of satellite transmission is normal and in
no way implies injury, capture, or death. The last transmission
placed Lisa only 50 kilometres from St Eustatius but
she also travelled and spent some time around the Virgin
Islands, possibly nesting there. Her last transmission
was from the uninhabited cay between St Bartholomew
and St Maarten.
Grace was the other turtle fitted with a tracking device.
Her name was chosen by Naomi Smith, age 11, who also
was one of the 2005 winners of the art and craft competition.
This green turtle was seen on September 18th 2006, and
a satellite transmitter was attached to her carapace
that same night. While up on the beach, she laid a clutch
of 129 eggs. She has a carapace length of 106 cm and
there has never been a record of her during the four
years of the turtle-monitoring program on the beaches
of St Eustatius. Her last transmission came on the June
6th 2007, from the waters of St Kitts and Nevis. The
tracking showed unusual behaviour in that she did not
travel as far as most green turtles during this period
of time. As with Lisa, the loss of transmission took
place around the expected time for the battery to expire
and does not raise any questions about the wellbeing
of the turtle. In total, Grace journeyed 4412 kilometres
but remained around the islands of St Eustatius, St
Kitts and Nevis.
She was also in the same foraging areas
as two green turtles from Guadeloupe, Coccinelle and
Laeticia. Coccinelle and Laeticia are turtles that were
released from the French West Indies Island of Guadeloupe
at the end of August 2006. They are a part of a satellite
tracking project of the Marine Turtle Research Group.
The progress of these turtles, along with turtles found
on other nesting beaches around the world, are tracked
by www.seaturtles.org.
Through this tracking study, the Dutch Caribbean Nature
Alliance (DCNA) aimed to learn the geographical range
of marine turtles breeding on islands of the Dutch Caribbean.
Also, DCNA wanted to engage the public in turtle conservation
issues by showcasing turtles' migratory behavior and
building local capabilities for performing advanced
sea turtle conservation projects. As an aside, an ancillary
benefit to this was an opportunity to look at foraging
ground movements as the primary objective of capturing
turtles’ migratory movements. The 2006 DCNA turtle
tracking effort is a collaboration between CARMABI (Curacao),
St Eustatius National Parks, and the Nature Foundation
Sint Maarten. [go up]
STENAPA and BroadReach
clean Atlantic Beaches.
|
Broadreach
group on Zeelandia Beach |
On the 30th of June, STENAPA, BroadReach and the general
public joined together in a collaborative effort to
clean up some of Statia’s beaches. Zeelandia,
along with Turtle Beach, was made cleaner of plastic,
paper, Styrofoam, diapers, and washed-up tyres by Saturday
night. The motive was to offer a cleaner beach for both
residents as well as nesting sea turtles to enjoy. Zeelandia
Beach is the primary nesting beach where critically
endangered marine turtles come to nest. Leatherback,
Green and Hawksbill turtles have been seen nesting on
Zeelandia. Cleaner beaches provide nesting females and
hatchlings with a better chance of survival. Garbage
left in the sea or on the beach can obstruct nesting
grounds and trap emerging hatchlings. Plastics are also
a threat as they look like the leatherback’s favorite
food: jellyfish. Over half of the sea turtles found
dead have plastics lined in their intestines.
Over 30 people worked vigorously on Saturday afternoon
for almost two hours to make the Atlantic beaches a
nicer place. In total over three truckloads were hauled
away including a broken buoy and several tires. In addition
to STENAPA staff, interns and volunteers, over twenty
BroadReach members participated in the beach cleanup
and three members of the public, including a four month-old
baby.
Later this month, BroadReach groups will also be helping
to improve Couchar Mountain trail and to clear Corallita
from the Quill entrance trail and from the Botanical
Garden. The BroadReach group is comprised of mostly
US teenagers, ages 13-18, that sail around the Caribbean
and offer summer adventures for teenagers, including
scuba, sailing, marine biology, academic and wilderness
programs that span the globe. Furthermore, the BroadReach
group provides opportunities for these teenagers to
learn new skills while providing a valuable community
services such as beach cleanups, trail building, road
clearing and neighborhood cleanup beautification projects.
Foundations interested in having BroadReach students
to help on a project this month should contact the National
Park visitors centre with details. Further information
about future beach cleanups or other upcoming activities
of the St Eustatius Sea Turtle Conservation and Monitoring
Program are available at the visitors centre in Gallows
Bay (tel 318 2884). [go up]
Stenapa Summer Club
a huge success
|
Ranger Carlton
van Putten leading the Stenapa Summerclub |
St. Eustatius National Parks’ Summer Club for
kids started with a bang yesterday. A total of 24 children
aged eight to 13 have signed up for the month-long club
which includes hiking, snorkeling and turtle education
activities. The aim of the Summer Club is to encourage
local children to be more active, while at the same
time learning more about some of the fascinating plants,
animals and marine life that can be found on their island.
Participation in the club is higher than usual thanks
to financial support from John and Danielle Wiginton
from Vecenergy Resources, who felt the course was a
great incentive and agreed to sponsor up to 30 children.
The activities began with a visit to the Miriam C. Schmidt
Botanical Garden where the children were given a tour
by Ranger Carlton van Putten. They then played a game
in which they each were blindfolded and had to identify
certain plants or flowers from their smell. These included:
white cinnamon, frangipani, Curacao sage, lemongrass,
basil and jasmine. After the game the students walked
up the Bird Trail leading into the Quill National Park,
identifying flora along the way and learning more about
the Red Bellied Racer snake which lives in the park.
To end the morning session, students played a game called
“Who Am I?” in which they had to guess which
plant or animal they were by asking questions.
STENAPA’s Summer Club runs from 2 July to 2 August
every Monday, Wednesday and Thursday. The club is coordinated
by Stenapa staff and assisted by interns and volunteers.
Each child receives a free Stenapa t-shirt and use of
snorkeling equipment. Students can look forward to hikes
in the Quill National Park, boat rides to snorkel sites,
and learning more about the life of sea turtles that
live in Statia’s waters. Stenapa wishes to thank
Vecenergy for their support in helping make the club
a success. [go up]
First Baby Hatchling
Waves Hello To Statia!
On Friday, May 25th, the first baby hatchlings emerged
from Zeelandia beach. Leatherback hatchlings were found
at approximately 7:07 AM by Marine Turtle Program Coordinator,
Arturo Herrera, and STENAPA Intern, Lauren Maloney.
Mr. Herrera noticed a pair of Yellow-Crested Night Herons
congregating in an area where a leatherback had nested
at the end of March. The Turtle Coordinator chased off
the birds. Sadly a heron took off with a hatchling in
its mouth. It was not determined how many baby hatchlings
were eaten as there were numerous tracks of both birds
and baby hatchlings. When Mr. Herrera and Ms. Maloney
arrived, there was only one hatchling left and it was
upside down. Ms. Maloney assisted it by turning it right
side up and it made its way to the sea.
Around two in the afternoon 19 more hatchlings emerged
but unfortunately three of them succumbed to the heat
of the sun’s rays. Reactions were varied from
the group of onlookers present, from excitement to awe.
STENAPA intern Lawrence Cook was almost moved to tears
by the experience of seeing the little hatchlings. There
were over twenty present to witness the beginning of
a remarkable journey. In total, twenty hatchlings made
it from Zeelandia Beach to the Atlantic to begin their
amazing voyage. Four died, including at least one from
a bird.

Junior Ranger
with baby turtle |
Leaving the nest is a group activity that can take several
days. The first turtles to hatch wait until more are
freed. This creates a small air pocket that gives the
hatchlings room to move. The activity of one turtle
triggers the movement of others so they move as a group
towards the surface. Hatchlings usually emerge from
their nest at night in response to cooling surface temperatures.
The hatchlings probably started moving upwards the night
before and reached the surface early in the morning.
Almost nothing is known about the first years of a Leatherback's
life after they leave as hatchlings. The hatchlings
make it to the sea after emerging from the nest and
are not seen again until many years later when the adult
females, which have survived the countless predators,
find a beach on which to lay their first clutch of eggs.
The 'lost years' in between are a mystery. Only a few
hatchlings in 1000 will survive to maturity and lay
eggs of their own. Many are killed, especially by man,
before they reach this age. Sometimes we do not kill
them directly, but still they perish from our activities.
For example, can drown when they become entangled in
fishing nets. Also, turtles are very sensitive to light.
The hatchlings are attracted by these artificial lights
and crawl inland. These hatchlings never find the sea
and they often die in the morning sun. Finally, turtles
can mistake plastic bags for jellyfish and die when
their stomachs become packed with plastic.
As with all reptiles, it is the temperature of the eggs
during incubation which decides whether the hatchling
will be male or female. In the case of Leatherbacks,
the critical temperature seems to be just below 29o
Centigrade. Above that temperature there will be more
females and vice versa. For this reason, the hatchlings
from the top of the nest are more likely to be female
as it is hotter nearer the surface. Incubation can take
from 60 to 75 days, depending upon the temperature in
the nest. [go up]
Statians Gather
to See off Baby Leatherback Hatchlings and Greet New
Sea Turtle Intern
On the 19th of June, over 50 curious onlookers gathered
at Zeelandia Beach to witness the release of leatherback
hatchlings. The crowd was anxious to see the release
of baby leatherbacks that had been spotted at 7.15am
that day by Marine Turtle Program Coordinator, Arturo
Herrera, and newly-arrived Marine Turtle Intern, Shizu
Fukui. When Mr. Herrera had approached one of the nests,
he noticed four tracks and two tiny leatherback hatchlings
on the sand. One hatchling was on its back, the other
had succumbed to the heat of the early morning sun.
The two other tracks led to diverse endings - one to
the ocean, and the other tracks met directly with larger
bird tracks, possibly a tri-Colored Night Heron or a
Green Backed Heron.
Later that day at 4.15pm, the Marine Turtle Program
Coordinator went out to investigate the nest and found
that just below the surface were more hatchlings ready
to make their incredible journey to the ocean. Mr. Herrera
phoned interested members of the public who had stated
beforehand that they were interested in viewing the
release of these Critically Endangered animals. Over
50 people gathered to attend the occasion. Those who
came out included members of the Statia Police, Dwight
Barran who filmed the scene, local Divemaster and head
of the Fisherman’s Association, Renaldo Redan,
STENAPA’s Junior Ranger Graduates, members of
the St Eustatius Medical School and Dutch tourists.
Mr. Herrera had dug the nest to ensure that all the
hatchlings were taken out of the sand and gathered the
hatchlings in a 5-gallon bucket for safekeeping. After
digging and finding no more leatherback hatchlings,
Ms. Fukui directed the crowd on appropriate tips for
viewing the hatchlings and not obstructing their way
to the ocean. She, along with Junior Ranger graduates,
released 10 healthy hatchlings who all found their way
towards the ocean. It took a little over an hour for
all baby hatchlings to locate the Atlantic Ocean and
start their perilous journey.
After hatching, the baby turtles dig out of the nest
and scurry to the ocean, usually in a group. It is thought
that during incubation, or immediately following emergence
from the nest, the hatchlings’ directional sense
is imprinted on to the earth's magnetic field. This
“imprinting” helps guide them back to the
same site to lay their eggs when they reach breeding
age. Although the first two months of their lives are
on land, or just underneath the surface, marine turtles
spend most of their lives in the sea. Females come back
to the beach only for nesting while males never return
to land.
If you wish to learn more about viewing nesting turtles
or other research activities of the St Eustatius Marine
Turtle Conservation and Monitoring Program, information
is available at the National Park visitors centre in
Gallows Bay, or call 318-2884. Furthermore, souvenirs
such as T-shirts and jewelry can be purchased at the
National Park visitors centre to help support the Marine
Turtle Program. [go up]
Two Dead Turtles Found
During the Month of May
|
Drowned
turtle stuck in a net |
On the morning of 16th of May, STENAPA staff came across
a drowned Hawksbill on the City Harbor. The juvenile
hawksbill had been trapped in the net of a local fisherman
and could not free itself from the nets, subsequently
drowning. This has raised the tally of two turtles that
have been found dead in Statian waters since the beginning
of May. On the first of May, a Leatherback was found
washed ashore missing its head and front and back flippers.
The hawksbill that was found last Wednesday was commonly
seen in Statian waters and considered a resident of
the local waters. It had been measured at no more than
50 cm. It could not be determined how long the turtle
was trapped in the net, but STENAPA staff determined
that the turtle was dead before they reached it and
had an opportunity to free it. The fisherman had no
knowledge of its incidental capture. The hawksbill is
considered a critically endangered species by the World
Conservation Union (IUCN) losing over 80 percent of
its species in 50 years. Over-harvesting is one of the
major causes of the decline in hawksbill populations
worldwide. International trade in tortoiseshell is now
banned and many governments have passed legislation
against its sale in local markets.
The hawksbill is one of the smaller sea turtles, usually
found in the tropical and subtropical waters of the
Atlantic, Indian and Pacific Oceans. It can be easily
identified by its beak-like mouth adapted for picking
sponges from coral reefs and its beautifully patterned
brown and gold shell. The sponges that they eat contain
glass needles called "spicules". It is commonly
thought it takes 20 to 30 years of age to reach sexual
maturity. This particular hawksbill was thought to be
no more than aged ten years.
On the 1st of May, a dead leatherback turtle was encountered
by the Marine Park intern, Mirella Wognum, on Zeelandia
Beach during a morning track survey. The Programme Co-coordinator,
Arturo Herrera, assisted by Marine Park interns Liz
Hartel and Mirella Wognum, performed a rudimentary necropsy
to determine the cause of death.
On initial examination it was discovered that the turtle
had no plastron and most of the internal organs had
been eaten. On preliminary inspection very little remained
of the turtle except its carapace. It was realized that
this turtle nested on 19 April 2007 as she was identified
by a barnacle on her left side of her shell. It is speculated
that all bites occurred post-mortem. The Programme Coordinator
was able to conduct a very basic necropsy. The remaining
internal organs were examined; none showed signs of
disease or damage. The reproductive organs showed her
to be female and the ovaries were developed indicating
that she was breeding adult. Unfortunately no definitive
answer as to the cause of death was determined from
the necropsy.
The leatherback turtle has been classified world-wide
as Endangered since 1970. While adults are at sea, their
major threats are from humans. Ingesting plastic, rubber,
tar, oil, and other synthetic materials can kill an
adult leatherback or severely injure it. Many have been
injured by colliding with boats, especially in shallow
water. The equipment associated with commercial fishing,
including lines, nets, ropes, and cables can entangle
adult turtles and can cause drowning. [go

Large leatherback turtle
nests on Statia
|
Leatherback
turtle nesting on Zeelandia Beach |
On the night of 10 April, 2007, a female leatherback
returned to the beach she was born, Zeelandia Beach,
to nest. She was met by a small group of interested
people to watch her nest activities and she did not
disappoint. Around 1:15 AM, the female began laying
her eggs.
Among the onlookers were four interested members of
the public, five volunteers and three interns for St.
Eustatius National Parks, one STENAPA staff member and
the Marine Turtle Programme Coordinator, Arturo Herrera.
The nesting female was a leatherback that had never
been previously recorded. She was tagged on her rear
flippers so she can be identified when she returns or
is seen by another turtle project within the Caribbean
region.
“It was real interesting to look at” stated
Nadio Spanner. “That was the first time I saw
a leatherback. It was my first time. I didn’t
know they came to Statia. They get real big.”
The female took just over an hour to finish and most
of the onlookers got to see the majority of the egg-laying
process. This female recorded the second known nest
on Statia. “I believe that getting the public
interested is important because these are Statia’s
turtles and the public should be excited getting such
a unique animal on our beaches.” stated Mr. Herrera.
The process of this critically endangered animal is
a unique, yet arduous process. When a turtle has found
the right place, she will excavate a body-pit, using
all four flippers to throw out the sand. She makes a
shallow depression for herself in the sand. The hind
flippers alternate digging, excavating an egg chamber.
Once the egg chamber is completed, laying will commence.
Eggs drop into the chamber three or four at a time;
their soft-shells ensure that they don’t crack.
During the actual egg laying, the turtle goes into a
semi-trance. The turtle covers the eggs when finished
and fills the nest with sand, using her hind flippers
to firmly pack the sand down. With the chamber filled,
she disguises the nest by scattering sand with all four
flippers. As the turtle moves and turns, the sand is
scattered making it hard to locate to exact location
of the eggs. Shortly, it is impossible to tell where
the egg chamber is concealed. Eventually the turtle
will move towards the sea, leaving a large area of churned
up sand that hides the exact location of the egg chamber.
After approximately 60 days, the hatchlings emerge to
start the life cycle.
The Leatherback turtle’s carapace has a texture
similar to leather, which is the reason for its name.
Its shell is very different from all other turtle shells,
which are strong and hard. The Leatherback is the most
widely distributed of all sea turtles, ranging through
all the oceans from the sub-Arctic to the southern extremes
of all continents. The species can travel over 5,900
km (3,600 miles) in its search for food, but despite
traveling these large distances the females will always
return to the same area to nest.
Further information about viewing nesting turtles or
other research activities of the St Eustatius Sea Turtle
Conservation and Monitoring Program are available at
the National Park visitors centre in Gallows Bay, or

Transmitter turtles
making waves
Two turtles outfitted with satellite tracking transmitters
as part of a migration behaviour study have made waves
since leaving St Eustatius. A hawksbill turtle named
Lisa was fitted with a satellite transmitter on Zeelandia
beach on September 8th of this year and has happily
been making the uninhabited islands between St Barts
and St Maarten her home since the last third of October.
Grace, the green turtle, was fitted with a transmitter
this 18th of September at Zeelandia beach as well, and
currently has found sanctuary between St Kitts and Nevis.
|
Satellite
trajectory of sea turtle 'Lisa' |
The two turtles are part of an inter-island project
funded by the Dutch Caribbean Nature Alliance (DCNA),
involving St. Eustatius National Park (STENAPA) and
the Nature Foundation St Maarten. The aim of this study
is to have a better understanding of where the sea turtles
nesting on Statia and St Maarten travel to when they
leave. The migration habits of these species are not
fully understood and studies such as these are needed
to help identify possible threats turtles may face by
providing more information about their migration routes
between different habitats. Unfortunately, St Maarten
had very little nesting this season and no turtles from
St. Maarten were able to be equipped with satellite
tracking transmitters.
Lisa was the first hawksbill to be observed nesting
on St Eustatius for the 2006 season. She laid 143 eggs
on Zeelandia Beach, located on the Atlantic side of
the island. Lisa took off from Statia, and headed straight
to St Barts. She remained around the uninhabited islands
between St Barts and St Maarten for over 2 weeks before
moving to Anguilla for a few days. In late September
she started moving again, and traveled to the US Virgin
Islands where she stayed until approximately October
7th. Then Lisa started out for open water and appeared
to head back towards Anguilla but veered to the uninhabited
islands again between St Barts and St Maarten in mid-October
where she has been since.

Satellite trajectory of
sea turtle 'Grace' |
Grace was the first green turtle tracked from St Eustatius
in 2006. She laid 129 eggs on Zeelandia Beach. She was
never previously encountered during the four years of
monitoring on St Eustatius. Grace has not traveled as
far as Lisa. She initially started towards St Kitts,
but then looked as if she was heading back towards Statia.
On September 29th, 2006, the nightly turtle patrol saw
her as she finished nesting and returning to the ocean.
They checked the transmitter and everything appeared
to be in good order. Since then, Grace has headed south
and is presently between St Kitts and Nevis –
roughly 50km from her release site.
The turtles were named as part of an art and craft
competition, held in 2005 as part of the education programme
for the satellite tracking project. Lisa’s name
was chosen by Evan Hassel, a 4th grade student at the
Governor de Graaf School. Grace’s name was chosen
by Naomi Smith, aged 11.
Marine turtles survived the extinction of the dinosaurs
and many prehistoric animals but threats such as pollution,
fisheries by-catch, being hunted for their meat and
eggs and use of their shell in ornamental jewelry have
seen their numbers spiral. Currently, three of the seven
existing species are critically endangered while three
species are endangered. Green turtles are an endangered
species while hawksbill turtles are critically endangered.

Turtle Conservation and Monitoring Programme are available

September 2006 - The story
of Captain Scout of The Black Turtle
STENAPA St. Eustatius, Nature Foundation St Maarten
and the Saba Conservation Foundation will be diving
into the topic of WATER as their new educational school
project. The programme, sponsored by the Prince Bernard
Culture Fund, will run from September 2006 to July 2007.
The goal of this programme is to stimulate students’
interest in marine life.
The programme is suitable for students in cycle one
and the newly installed cycle 2 (former grades 3 and
4). As the title already implies, the WATER topic is
fitted into a pirate theme. The programme focuses on
marine life and the different characteristics of water.
In addition, a broader picture of the water cycle will
be discussed. The major awareness goals of this project
are that students learn about the importance of water,
our marine habitat and coastal vegetation. Hopefully
this awareness will result in the loss of fear of what
occurs in (at unknown depths of) the ocean and more
respect for underwater ecosystems.

Again the sea turtle mascot, Scout, is involved. Cursed
by the spell of greed, he becomes the wicked captain
of the pirate ship “The Black Turtle” and
he and his crew sail out to find a hidden treasure.
Each of their adventures during this journey is the
introduction to one new lesson on water. Topics that
will be discussed include: ‘scary underwater life
(or rather: defensive survival strategies that only
succeed by their chilling effects)’; ‘different
eating habits of underwater life’; ‘the
water cycle’; and ‘mangroves’. The
program ends with topics that discuss the physical characteristics
of water such as floating and surface tension. In the
end, Scout is freed from the curse of greed and returns
to the sea as the friendly turtle he always was.
All four primary schools are participating in this programme
with monthly class activities for each grade. If dive
schools or individual ocean visitors have nice stories
about our specific Windward underwater residents and
their habits or digital images which could help illustrate
the topic, they would be gratefully accepted and integrated
in this new educational program. Email dominique@naturefoundationsxm.org

September 2006: Survey of
new artificial reef for fishermen indicates increased
fish diversity

Terminal in February 2006. |
A recent survey of the latest artificial reef to be
created by St Eustatius National Marine Park indicates an increase
in the number of fish species in the area. The reef
project was initiated following a meeting with local
fisherman in February 2004; they requested that the
Marine Park create an artificial reef designated solely
for fishing, and not as a dive site. It was agreed at
that meeting to locate the new reef at a depth of 75
feet, west of the Southern Marine Reserve. Following
some equipment delays, the reef was finally completed
in February 2006 with the sinking of a pipe, concrete
mix barrel and the tug boat “Miss Cathy”.
The Marine Park wishes to acknowledge the assistance
provided by Statia Terminal in making this project possible.

Following a “settling-in” period of six
months since the sinking of the last reef structures,
a survey was conducted in August to assess the fish
population at the new reef. It was found that both diversity
and density of fish had increased when compared to the
results of the survey conducted prior to the creation
of the reef. Diversity increased from 14 to 18 species,
and more than twice as many fish were recorded than
in the initial survey. The new species were observed
in large numbers, in particular shoals of Bar Jack,
Blue Tang, Striped Grunts and Horse-eye Jacks, all drawn
to the area by the new reef structures. As had been
agreed upon in 2004 this site is only used for fishing;
there is no dive mooring attached, and the site is marked
for fishermen by a small brown buoy.
It seems that the new reef is also attracting other
marine life. Earlier this month local fisherman “Gordo”
caught the largest lobster ever recorded in the Statia
National Marine Park at this site; it weighed approximately seven
pounds.[go up]

This week saw the start of the next phase of the Corallita
Research Project being conducted by St Eustatius National
Parks Foundation (STENAPA) in conjunction with Dutch
botanists Dr Pieter Ketner and Joris Ernst. Following
a series of small-scale experiments at the Botanical
Garden that started in January and focused on different
herbicide application methods, larger scale trials are
now being planned. In a series of carefully controlled
experiments to be conducted for the next three months,
several plots will be treated with different concentrations
