Wellen JSC Just sit back, relax and enjoy this newsletter. For the first time in the history of this publication we are focussing largely on the sea. As you will see, marine biology research is heavily included in this issue. And with reason. Carmabi has been host to a large number of international scientists researching the many facets of coral reefs and other marine ecosystems, providing the island with extensive knowledge about these issues. Our main objective is to make Carmabi, once again, one of the top research laboratories in the Caribbean. And of course we will keep you informed about the breakthroughs in the research department. We started out in this issue by inviting Miss. Chantal Huijbers to write an article about the research work on migration of tropical fish, she and her undergraduates have been doing on the island for the last couple of years. Also, Carmabi was present at the 11th International Coral reef Symposium in Ft. Lauderdale (U.S.A.) in the person of Dr. Mark Vermeij. Much information about the state of coral reefs all over the world was shared during this symposium and we share some of this information with you in the article regarding the symposium. Other features include information of coral spawning and two new studies which were published recently on subjects such as fish distribution throughout the Caribbean and the dynamics of invasive algae. The new Clear Water Challenge of this year is featured on the next 13 page. We will be keeping nature protection on everyone’s radar with 13 the fun events we planned for October 25th and November 2nd. 16 Also in this issue the second part on the history of the Christoffelpark 16 as we promised in our last newsletter. All in all we think there is ample information in this issue that you should not miss. Feel free to contact us if you have any questions or suggestions by mailing us at info@carmabi.org. Enjoy!

Ryan kayaked around Curacao in 2007 to put nature and its protection on everyone’s radar. Now its your turn to help him and let nature remain on the radar. The Clear Water Challenge 2008 is one way to do that. Clear Water Challenge 2008 Together with Amigu di Tera and Jeugd Sport Centrale, Carmabi will organize challenges for kids and adults in the months of October and November. Kids Clear Water Challenge Jeugd Sport Centrale, well known for its annual “vijfkamp” for schools, exists 35 years this year. It starts its celebrations on October 25th with a personal challenge for nature for almost 3000 kids in the Christoffelpark. Together with a large number of volunteers and of course Ryan de Jongh himself, they will hike the northern route in the park to give nature a voice and show everyone how important conservation is. Amigu di Tera’s “A”-(Antartica) Team will be joining the group of children and by doing so, make the voice a stronger one. The north side of the park will be closed for the entire day, which means that on October 25th the north side of the park will be closed for the general public. Stay tuned for more information about this powerful happening. Clear Water Challenge 2008 Several important things resulted from last year’s Challenge: it influenced the installment of the Green Team with Ryan de Jongh as godfather by commissioner Eugene Ruggenaath, preparations for the Marine Protection Ordinance (which at this moment has not been installed), and several other nature protection rules and guidelines. It is important to keep nature and the need for its protection on the radar of everyone. Something Ryan wants more than anything is to make sure that natural areas stay protected and that the coastline remains accessible to the public. The Christoffelpark is one of his favorite locations on the island and he is often seen there while climbing the mountain several times as part of his training. In addition, 2008 is a year of many celebrations: the Christoffelpark exists 30-years, the Curacao Marine Park exists 25 years and it’s the international year of the reef. Amigu di Tera, a non-profit organization having basically the same goals that Ryan has, joined 3 Carmabi Clear Water Challenge 2008 Let’s show that we care, stand up and give nature a Voice! the Challenge and together we decided to organize a social event on November 2nd in which Ryan makes another statement for nature. And everyone can join! “Boka Grandi, point of entrance of the Christoffelpark during Ryans Challenge and Christoffel Mountain, the last part of the route..” 100 km Challenge On November 2nd at 03.00 AM in the morning, Ryan de Jongh and Leon Pors will start kayaking from the Marine Park Visitor Center at Carmabi Piscadera and will paddle to Playa Piskado at Westpoint (40 km). From here Ryan will continue his Challenge on a mountain bike and bike from Playa Piskadó to the main entrance of the Christoffelpark. This bike ride will take him past Shete Boka, Boka Grandi and the northern car route in the Christoffelpark (20 km). At the main entrance he will leave his bike and hike all routes in the southern part of the park, including the green route, the orchid- and Zevenbergen trail and last but not least: climbing the mountain to collect a flag to celebrate the completion of the challenge (all hiking routes: 40 km). Everyone is invited to make this challenge a personal one and give nature a voice. Bike with us, hike certain parts, or the entire hike with Ryan and give us a hand keeping nature on the agenda! How to participate? Everyone interested in participating can join us. Fill in your form at Carmabi on October 15th from 12.00-18.00 PM or from the 20th to the 24th of October at our Challenge booth in 4 the FATUM building from 18.0021.00 hrs. Participation to one section (biking or hiking) costs Nafl.10 per person. For two or more sections of the Challenge the fee is Nafl.20 per person. Take a look at our website www.carmabi. org for more information about the routes and procedures. Or email us at info@carmabi.org. Let’s show Curacao that we care, stand up and give nature a Voice! Challenge goals The most important goal for Amigu di Tera and Carmabi is for nature and its protection to stay on everyone’s mind, including our politicians who are responsible for the drafting of essential laws and other protective measures. By showing them that we care about this issue, we can give nature a voice in matters that are often forgotten or set aside as not important. We are not specifically aiming for a monetary goal with this Challenge. All revenues from inscriptions and additional sponsoring will go to educational projects focusing on the sea. But if you feel the need to assist us financially, do not hesitate to contact us! Of course we will take all measures to limit the impact on the park to an absolute minimum. Our rangers and volunteers will make sure that the children stay on the paved route, and groups and schools have to stay together to limit mingling and hence uncontrollable situations. CARMABI news!/ Education ENNIA sponsors Christoffelpark Outdoor Center with 30.000 guilders! ENNIA Insurance Company sponsored Christoffelpark with a total of 30.000 guilders to be paid in a period of three years in amounts of 10.000 guilders a year for the establishment of the Christoffelpark Outdoor Center. This Center will be the central point of sales for tours and hikes as well as mountain bike rentals and other nature-related activities. With this sponsoring we are able to restart the mountain bike rental in the park and upgrade the existing camping facilities to accommodate larger groups. When the complete make-over of the Savonet plantation house and other buildings are complete, the Outdoor Center will move into its own location in the central visitor area around the museum. We thank ENNIA very much for their generous support! Scarlet Ibis still around! We mentioned the presence of the first Scarlet Ibis youngster on the island last year. Since that moment it has been spotted several times in the neighborhood of “Klein Hofje”, Malpais and “Vaarsenbaai”, both places near Piscadera. Now however, the bird has transformed into its phenomenal scarlet plumage and can no longer be overlooked or confused for any other species. There is still only one confirmed individual on the island. The animal often roosts with small groups of Cattle egret (Bubulcus ibis) and Snowy egret (Egretta thula) in mangrove clusters in the Piscaderabay. “Scarlet Ibis at Vaarsenbaai.” Photo by: Gerhardus Wellen Educational programs started! Our educational officers visited the local primary schools to subscribe all schools for the environmental education programs for the school year 2008-2009. We are starting two new programs this year, that take place at the Carmabi/ Marine Park Visitor Center at Piscadera. These programs are designed for the old 3rd grade of primary school (or 5th group in the FoundationBased Education system). One of these programs is about the coral reefs of the island, providing students with basic information about these marine ecosystems and provide them with the opportunity to observe several reef creatures themselves. The second program focusses on the bats on the island and their importance to the terrestrial ecology. Students come to Carmabi with their teachers and will be given a full morning program by one of our educational officers. 5 Scientific Research Coral Spawning 2008 “Brittle star releasing red eggs” “Sea urchin releasing sperm” This year Carmabi once again organized several lectures on the biology behind the annual coral spawning. During a period of three days, multiple invertebrate species such as corals, gorgonians, sea urchins and sea stars reproduce during the night. This amazing phenomenon is often mentioned as one of nature’s greatest miracles. Together with several dive schools around the island, lectures were held during which those interested could learn about what happens with the eggs after the corals released them in the water, how larvae are formed and how these find their way back to the reef to start building a coral colony themselves. Approximately a hundred people attended the presentations. Researchers from Carmabi, in cooperation with scientists from the SCRIPPS Institution of Oceanography (San Diego, U.S.A.) then set out to study this year’s coral spawning at several locations around the island. At night, large plastic tents were placed over coral species expected to spawn, i.e. release their reproductive material (gametes), and when they did the floating eggs and sperm released by the corals was collected using a specially designed collector at the top of the net. All gametes were then mixed so fertilization could occur after which the embryo’s were brought back to the laboratory at Piscaderabaai. Here the embryos are presently reared in filtered seawater so they can develop in larvae. This will take approximately take one week after which the coral larvae will be used in various scientific experiments. The main goal of these experiments is to determine whether water pollution leads to higher abundance of bacteria that then cause coral larvae to die. Some of this work was already conducted at Carmabi during last year’s coral spawning and the results were presented during the International Coral Reef Symposium that was held in July of this year in Ft. Lauderdale (FL, U.S.A.). The main event of this year’s coral spawning, i.e. the release of gametes by mountainous star coral (Montastraea faveolata) the major reef- building coral species on Curacao, occurred on September 21st , resulting in a spectacular “upside-down snow storm” on the reef consisting of coral gametes floating to the water surface. Many other species that spawned were observed as well, including gorgonians, sea urchins and several other coral species. Migrations of tropical coral reef fish: where do they go and how do they get there? “Chantal Huijbers @ work.” The island of Curaçao is surrounded by a beautiful coral reef, with which hundreds of fish and invertebrate species are associated. For years, the Animal Ecology group from the Radboud University in Nijmegen has been conducting research at Carmabi, 6 led by Dr. Ivan Nagelkerken. Currently, Chantal Huijbers is conducting her dissertation research, which is focused on the use of mangroves and sea grass beds by coral reef fish. Most coral reef fish species have a pelagic larval stage during which they float around in the ocean, before they change into larvae with strong swimming and orientation abilities and then settle on the reef. Besides fish species that spend their entire life on the coral reef, some species are known to use back reef habitats, like sea grass beds and mangroves, during their juvenile life stage. These species include, among others, the French grunt, Yellowtail snapper, Schoolmaster, Barracuda, Gray snapper and Striped parrotfish. On Curaçao, we find mangroves and sea grass beds in bays like Spanish Water Bay, Piscadera Bay, St Joris Bay etc. It is believed that these bays provide more shelter against predators, and as such they may favor growth and survival of the fishes. In the absence of sea grass beds or mangroves, the abundance of some coral reef fish species is significantly lower on adjacent reefs, which stresses the importance of the conservation of these habitats. One part of Chantal’s research focuses on the existence of migrations of fishes from bays with mangroves and sea grass beds to adjacent coral reefs. In order to do this, different methods are being used. One of these methods is to tag fishes in the bay with so-called coded wire tags. Each tag has a unique code, which makes it possible to identify individual fishes. On the coral reef, fish are caught and then scanned for presence of a tag. If a tag is recovered this will prove direct migrations from the bay to the reef, and besides that it will give information on the growth patterns of the fish. Another method to study Scientific Research migrations is by use of stable isotope analysis in muscle tissue and ear bones of fish. Concentrations of stable isotopes, like carbon, of juveniles will be compared to those of adults on the reef. This will reflect if adults have spent some time in the mangroves or sea grass beds during their juvenile life stage. Another objective of the research project is to reveal the mechanisms which are used by these fish species to detect certain habitats. Recognition of suitable settling sites has been hypothesized to be based on acoustic, chemical, solar direction, magnetic, visual, wave motion or thermal cues. By use of choice experiments, Chantal will try to determine the importance of smell, sound and vision in tropical reef fishes. Fish from different size classes (pre- and post-settlement, juvenile and adult stages) are tested on their ability to detect sea grass beds, mangroves, coral and rocky reef habitats by visual, chemical and sound cues. The study is set up to reveal the mechanisms on how fish larvae find mangroves and sea grass habitat when settling from the open ocean, and how subadult fish find the coral reef after having grown up in the bays. By revealing migration patterns and mechanisms of coral reef fish species which are associated with mangroves and sea grass beds during their juvenile life stage, the connectivity between these habitats can be determined. Connectivity is a crucial parameter in models of marine population dynamics, and therefore most important for the management of the marine environment. 7 “ French Grunt.” “Mangroves.” “Barracuda.” Scientific Research Two new Carmabi studies published in international scientific magazines This month two studies conducted at Carmabi have been published in the “Journal of Biogeography” and “Biological Invasions”. The first reports on the distribution of fish species throughout the Caribbean and was conducted in cooperation with the SCRIPPS Institution of Oceanography (U.S.A.) and the National Center for Ecological Analysis and Synthesis (U.S.A.). The goal of the study was to test fundamental predictions of biogeographical theories in tropical reef fish assemblages, in particular relationships between fish species richness and island area, isolation and oceanographic variables (temperature and productivity) in the insular Caribbean. These analyses complement an analogous and more voluminous body of work from the tropical Indo-Pacific. The Caribbean is more limited in area with smaller inter-island distances than the Indo-Pacific, providing a unique context to consider fundamental processes likely to affect richness patterns of reef fish. It was found that diversity of reef-associated fishes increases strongly with increasing island area and with decreasing isolation. Richness also increases with increasing near shore productivity. Within the relatively small and densely packed Caribbean basin, fish species richness fits the classical species– area relationship. Richness also was related negatively to isolation, suggesting direct effects of dispersal limitation in community assembly. These results highlight fundamental 8 mechanisms that underlie spatial patterns of biodiversity among Caribbean coral reefs, and which are probably also are functioning in the more widespread and heterogeneous reefs of the IndoPacific. The second publication looked at the dynamics of invasive algae of species that are native in the Caribbean, but were accidentally introduced in Hawaii. This study was conducted in cooperation with the University of Hawaii (U.S.A.) and the University of the Virgin Islands (USVI). Humanmediated introductions of nonnative marine species have broken down the historic biogeographical separation between floras and faunas in various parts of the world. An interconnected global economy now allows for unnatural long-distance transport of marine organisms beyond their natural dispersal boundaries. The intake and release of ballast water by ships, ‘‘hitchhiking’’ on floating debris and ships, the aquarium trade and intentional introductions for aquaculture and fisheries enhancement represent the most common routes by which such transport takes place. While many introductions are unsuccessful, some introduced organisms become extremely abundant which can negatively impact native flora and fauna. Such introduced species are often referred to as ‘‘invasive species’’. Because invasive species presently cause major economic losses and local and global reductions in biodiversity, understanding the factors that allow species to become abundant after they are introduced, is a critical step towards future prevention and management of marine invasions. Macroalgae represent roughly 20% of the world’s marine invasive species that cause significant local ecological and economic damage by altering the structure and functioning of ecosystems they invade. For invasive macroalgae and invasive species in general, regulatory processes that control their abundance in their native range often no longer exist or have changed at their new location. A commonly proposed mechanism that builds on this premise is the Enemy Release Hypothesis (ERH). The ERH states that introduced plant species increase in distribution and abundance because coevolved herbivores or other natural enemies are generally not transported with them to the invaded location. The effects of the ERH become enhanced when introduced plants face ample supply of resources at their new location that can be allocated to growth and reproduction. The study aimed to quantify the difference in herbivore pressure experienced by two native and two invasive macroalgal species in their native (Caribbean) and invasive range (Hawaii). Secondly, the same species were provided with additional nutrients to see whether invasive species respond differently to higher resource availability than their native congeners. This information will aid in determining if (1) the negative impact of local herbivores on plant growth differs between Scientific Research a species’ native and invasive range, thus providing a species with ‘‘enemy release’ sensu the ERH, and if (2) invasive species respond differently to increased nutrient availability compared to native species, suggesting that biogeographic differences in nutrient availability could drive invasive success. Herbivorous fish suppressed growth of invasive algae in their native (Caribbean) and invaded range (Hawaii), but despite similar levels of herbivore biomass, the intensity of herbivory was lower in Hawaii. Algal species with a circumtropical distribution did not show a similar effect of herbivores on their growth. Nutrient enrichment did not enhance growth of any algal species in either region. The reduction in herbivore intensity experienced by invasive algae in Hawaii rather than an escape from (native) herbivores provided invasive macroalgae with ‘‘enemy escape” sensu the Enemy Release Hypothesis (ERH). Since native, Hawaiian herbivores still feed and even prefer invasive algae over native species, invasion scenario’s that involve predation (e.g. the ERH) could be falsely dismissed when invasive species are only studied in their invasive range. We therefore argue that escape from herbivores (i.e. enemy release) can only effectively be determined with additional information on the intensity of predation experienced by an invasive species in its native range. “Algae on a beach.” Picture by: Dr. Mark Vermeij 9 Scientific Research Carmabi present at 11th International Coral Reef Symposium in Ft. Lauderdale (FL, U.S.A.) Every four years all coral reef scientists and marine park managers from all over the world come to gather to discuss the latest scientific and management information for coral reefs during the International Coral Reef Symposium (ICRS). In July this year the symposium was held in Ft. Lauderdale (FL). 3500 people from 75 countries attended the symposium and Carmabi was represented by the new science director, Dr. M. Vermeij. A special poster was designed to advertise Carmabi as a venue for research by those attending the symposium and so far 20 research groups have shown interest to conduct future research project in Curaçao. In addition, presentations of research findings of work conducted at Carmabi were presented to the large international audience Coral reefs continue to suffer fever-high temperatures. A defining theme of the 11th International Coral Reef Symposium is that the news for coral reef ecosystems is far from encouraging. Climate change is now much faster than in an iceage transition, and coral reefs continue to suffer fever-high temperatures as well as sour ocean conditions. Corals may be falling behind, and there appears to be no special silver bullet remedy. Nevertheless, there are hopeful signs that we should not despair. Reef ecosystems respond vigorously to protective measures and alleviation of stress. For concerned scientists, managers, conservationists, stakeholders, students, and citizens, there is a great role to play in continuing to report on the extreme threat 10 that climate change represents to earth’s natural systems. Urgent action is needed to reduce CO2 emissions. In the interim, we can and must buy time for coral reefs through increased protection from sewage, sediment, pollutants, overfishing, development, and other stressors, all of which we know can damage coral health. In short, the time to act is now. Over a third of the world’s coral species are at elevated risk of extinction. Reefs of the Western Atlantic have generally decreased in living corals since the 1970s, and although reefs of the Great Barrier Reef were resilient until 1996, they are now beginning to struggle. It is good news that reefs far from continents and direct human pressures, including Bermuda in the Atlantic; the Flower Garden Banks in the Gulf of Mexico; American Samoa, Fiji, Palau, and French Polynesia are still resilient and able to recover from damage. We still have some time! The degradation and ponderous recovery of many reefs are due to combination of the global stresses of climate change coupled with regional and local stressors including runoff from agriculture, other land-based sources of pollution, over-fishing, and habitat destruction associated with coastal development. Many studies have laid down stepping stones to understand ongoing changes in coral and fish community dynamics. A prime driving factor is climate change. NOAA satellites reveal tropical oceans have warmed at a significantly faster rate over the past decade. Coral cover in many locations remains low and is not recovering. This is especially true in areas that have experienced severe bleaching, a phenomenon on the increase with increasing ocean warming. Such changes are not restricted to corals. Coral loss clearly leads to loss of associated organisms; decreasing fish abundance and diversity, for example, go hand in hand with loss of corals and decreasing coral cover. The time to act is now! Ocean acidification and ocean warming can be thought of as the ‘evil twins’ of climate change. The same carbon dioxide that causes ocean warming is entering the oceans and causing chemical changes (i.e., lowered pH, lowered carbonate ion concentration) that affect marine life. Coral reefs are threatened because carbonate ions, essential for building their calcium carbonate skeletons, become less available. Reef structures are further endangered because lowered pH is likely to reduce resistance to erosion. There is mounting evidence that acidification can cause a slowdown in the growth of corals and in coralline algae, both vital to the reef structure. Results presented at the Symposium show that calcification rates in many corals are already declining from a combination of factors including increasing temperature, decreasing water quality, and ocean acidification. In addition, ocean acidification is now shown to reduce the ability of coral larvae and coralline algae to successfully settle and grow new colonies, which will affect the ability of degraded reefs to recover through reseeding with larvae. The Symposium witnessed many new science advances Scientific Research that increase our understanding about coral reef ecosystems. Several scientists used new genetic techniques to show that reefs are connected primarily at a scale of tens of kilometers (km). In contrast with previous thoughts that reefs were highly interconnected at scales of thousands of km, these studies show that only occasional pulses of propagules leave the reef ‘village’. Coral larvae settle in close proximity to their parents, and some fish are homing in to local coral heads after tens of km of travel. Such local connectivity suggests that local protection and management will lead to local benefits. Action and protection also buys time for adaptation. Simultaneously we must not lose sight that important ecological connections and stressors (e.g., migration, larval transport, upwelling, pollution, pathogens, climate change) also exist at the larger ecosystem scale. Molecular tools are revealing a diverse array of microorganisms living around and in association with reefs and able to adapt subtle environmental shifts. The microorganisms have vital roles in reef health, but if perturbed, these roles can break down in a variety of detrimental ways and lead to infection and disease. Researchers are reporting a link between coral disease and environmental change, and even viruses are now implicated in coral disease and associated coral tumors. Yet, there is also some evidence of developing immunity, whereby Vibrio and other bacteria that once caused harm to corals are no longer found in association with the coral-disease. By 2015, half the world’s population will live along a 11 Scientific Research narrow band of coast, putting unsustainable pressures on coastal resources. There will be coral reefs in our future only to the extent that they are valued by people. Understanding the value of reef ecosystem goods and services can help to promote protection and thwart degradation. Economic benefits, incentives, and cultural values need to align with conservation efforts. Social scientists have much to contribute to this aspect as well as towards environmental use planning within local and regional areas. Likewise, managing reefs must include managing people’s behavior toward reefs. Social science can help us understand the root causes of people’s behavior, including poverty, global demand for fish products, and tourism. Rising food and fuel prices can put greater fishing pressure on near-shore reefs. Fisheries catches from many islands are vastly underreported, and fish populations severely depleted and in critical condition. Local action is one key method to achieving management success, and communities and government can be effective stewards of coral reefs once it is understood that it is in the interest of the public and individual good to do so. Linking coral reef conservation to human welfare: ‘Healthy Reefs for Healthy People’, is a useful theme to be repeated with ties to tourism, livelihoods, food security, as well as cultural and spiritual well being. Marine Protected Areas are multiple-use areas, in which various tools, particularly zoning, are used to protected marine resources (marine reserves or no-take areas), define and confine human uses, separate conflicting 12 activities, and consolidate administration to eliminate duplication and overlap. Studies in the Philippines and Guam, for example, show that corals inside MPAs have less disease than fished areas which have large gaps in diversity affecting affect disease transmission. MPAs represent effective management tools and work best when providing interim benefits as well as longer conservation benefits. Scientists reiterated that MPAs are necessary but not sufficient. Protection of as much reef territory as possible recognizes that local efforts can build to regional ones which in turn can build into global ones. Organizational and scientific capacity is needed to establish and maintain marine management areas. In some cases, hybrid designs of no-take and periodically closed areas may better address economic needs of the community and conservation objectives. Healthy Reefs for Healthy People. The Symposium concluded that changes needed to protect the word’s coral reefs include: 1) convincing communities that reefs are at risk, 2) enlisting multiple levels of public, industry and government support, 3) providing necessary legislative and regulatory powers, and 4) conducting needed science with sufficient information transfer. In this way effective management rooted in broad interdisciplinary science and stakeholder buy-in, working at local, regional, and international scales, coupled with global efforts to reduce atmospheric CO2, will give reefs a chance. Christoffelpark Corner The history of the Christoffelpark (2) Christoffelpark is in a festive mood this year. The largest nature park of Curaçao celebrates its 30year anniversary. Time of course to take a look at the history of those 30 years in which nature protection and management were core issues. In our last newsletter we wrote about the period before the park was officially opened and the first years after its opening. In this article we take you along the development of Environmental Education in the park, the many attractions and activities which were developed during the years, the unique flora and fauna, Museum Savonet and of course the future. Environmental education in Christoffelpark From the very beginning, the park was a popular destination for schools wanting to do outdoor activities. The Christoffel Mountain was a popular climb, which was done by schools themselves and guided by park rangers. Other hikes were popular as well. However, efficient educational programs for school were nonexistent. This changed in the second half of the 80’s. The government appointed one employee to work for STINAPA with the sole purpose to develop Environmental Education programs for schools. This employee organized several workshops for teachers consisting of a wide variety of themes and for the different levels in the educational system. These workshops consisted of theoretical material and many excursions all over the island. Educational material was produced which was used by teachers for presentations. STINAPA produced and distributed audiovisual materials, organized presentations and took many initiatives so that Environmental Education became included in the curriculum of schools. In the 90’s these initiatives developed into packages so schools not only received educational materials to be used in the classroom, but also participated in excursions in which a trained educational guide accompanied the students. Thanks to government subsidies, sponsoring from the private sector and the appointment of an extra educational employee by the government, it became possible for all children between 4 and 12 years old to get acquainted with several natural areas during their school period. Christoffelpark was the focal area of these excursions. Even now, in the 21st century, you can come to the park on any given day and encounter groups of students during a daytrip to the park, accompanied by an educational guide, while discovering its ecological and cultural attractions. Attractions and activities From the very beginning, the Christoffel Mountain and the caves in the park were the most popular attractions for visitors. Several attractions and activities were developed to maximize the visitors’ experience of the park. Trails were made to see orchids and other special plants for visitors who were not so mountain and cave oriented. In 1989, the number of visitors increased to 20.235 paying visitors a year. In the same year a wooden deer observation tower was built next to the deer reserve. 13 Christoffelpark Corner “White-tailed hawk ” “Yellow Oriole ” “Common Emerald ” This reserve was part of a research project focused on the Curaçao white-tailed deer (Odocoileus virginianus curassavicus) that started a couple of years earlier. The tower gave visitors the possibility to observe deer without being noticed, under supervision of a trained ranger. After the research project was finished, the tower was used for special deer spotting tours, held in jeeps starting at the main entrance of the park. These tours are still part of the regular activities of the park, and the tower is still used during the tours. Several popular “open houses” were organized and expositions in the former Mangasina were often changed and adapted. Jay Haviser and Leon Pors reconstructed the skeleton of a whale in 1991. In 1992 Mr. Pors installed an expo about de geological history of the island, which formed a part of the attractions for many years there after. A few years later the nature exposition by Peter van der Wolf was installed, containing many materials and pictures of the park’s flora and fauna. In 2006 the nature exposition was removed and the skeleton of an 11-meter long Sperm whale was installed as part of an exposition about whales and dolphins, that had washed ashore on the island. This whale expo is the last one before the mangasina will be transformed into the natural history section of the Savonet Museum, expected to open for public around the end of December 2009. An other attraction in the park was the center for birds of prey, developed for educational purposes and with the intention to start breeding programs for endangered species on the long run. Unfortunately the project did 14 not go as planned and does not exist anymore. Horseback riding and mountain biking became possible, a cactus garden was developed, and animal presentations with iguanas, snakes and birds of prey became daily activities. Full moon excursions, deer spotting and jeep tours were added to the list of activities. At this moment, all these activities are once again part of today’s park’s programme, except for the bird of prey presentations and horseback riding. Unique flora and fauna The flora and fauna in Christoffelpark represent the island’s nature, represented by animals and plants composed of animals and plants that have adapted to dry and hot climate, where water and food are scarce during large parts of the year. Natural water wells, as well as the water supply from the cultural and historical heritage like water holes and man made wells provide animals with additional sources of water in dry times. Almost all species of flora and fauna on the island live in the park. Mammals like the white-tailed deer, the cottontail (Sylvilagus floridanus nigronuchalis), and several species of bats; birds like the rare white-tailed hawk (Buteo albicaudatus), the endemic subspecies of Barn Owl (Tyto alba bargei), hummingbirds like the Common Emerald (Chlorostilbon mellisugus) and the Ruby-topaz Hummingbird (Chrysolampis mosquitus), the endemic Yellow Oriole (Icterus nigronuchalis curacoensis) and even the Caribbean flamingo (Phoenicopterus ruber ruber) when the salt plains at Boka Grandi are filled with water. Reptiles and insects are also well represented. Orchids like the Lady of the Night (Brassavola nodosa) and Humboldt’s Schomburgkia (Myrmecophila humboldtia), the 3 pillar cacti species occurring on the island: the datu (Lemaireocereus griseus), the Kadushi (Cereus repandus), and the Kadushi di pushi (Cephalocereus lanuginosus). Some plants only occur in the Christoffelpark area, like the rare Myrcia curassavica, an endemic species for Curaçao, and the Maytenus versluysii, endemic for Curaçao and Bonaire. Museum Savonet Finally the many attempts to transform the Savonet plantation complex and its historical structures into a museum have met fertile ground. With the assistance of Dutch Development Funds by USONA, work has started to restore the buildings to their former glory and to establish space for a museum collection. The main theme of the museum will be interdependence between nature and culture during the long history of human beings on Curaçao. Starting at the beginning of the human occupation of the island, about 5000 years ago. Christoffelpark Corner Christoffelpark now and in the future A new age will start for the park, when the Savonet Museum opens its doors to public for the first time, in December 2009. This “new” Christoffelpark offers a great variety of regular and special activities and events, well maintained attractions, regular and special expos and of course many nature and culture related events. Combined these attractions will transform the park into a mustsee location for recreation and education for locals and visitors, for the young and the old. The museum will be well accessible for visitors in wheelchairs or using rollators. The educational program will be expanded. The outdoor center provides visitors with the chance to explore the park by guided hikes, safari trips, hiking trails, mountain bike trips, mountain climbs, team building programs and much more. And of course the management and protection of the natural assets will remain the most important core business. All will be done to expand the protected area and to offer facilities for researchers. The coming years many challenges will cross our way. Carmabi is more than ready to confront these challenges and to keep this beautiful area in the best of care. Opening Hours CHRISTOFFELPARK Monday- Saturday 7.30 AM -16.00 PM (no admittance after 14.30 PM) Sunday 6.00 AM - 15.00 PM (no admittance after 13.30 PM) Interested in camping, team building, company celebrations and/or other nature activities for groups: Call Cyrill Kooistra or Woti Samboe at 864-0363 15 “ Kadushi di pushi” “ Humboldt’s Schomburgkia” Savonet Museum Museum update As we were silently hoping for, the restoration process brings interesting details to life. Apart from architectural details and insight in the evolution of the color scheme (the main house of Savonet used to be white originally!), an old coin turned up! When one of the sliding windows in the central room of the main house was disassembled, a copper coin from 1828 was found in the space between the window and sill. Clearly someone lost this coin in the past, for us to find it. The next step will be to contact the coin museum for an official description and classification. We seriously doubt that the museum has been transformed into a museum in possession of a highly prized artifact, but who knows? Felix de Rooy was on the island again, to participate in an expert meeting on the heritage of slavery, and to continue his planning activities for the museum. The existing concept has been finetuned and some additional gaps have been filled during his stay. One of the working class jobs that we failed to high-light in the planning was the making of strawhats. We now have an exhibit on this part of history in the works as well. One area of concern is the need for a stable and dependable supply of electricity. The experiences of the last few weeks, with lots of black-outs caused by lightning, were not very comforting. Therefore, steps are taken to organize some sort of power back-up. The most wonderful solution would be to implement a sustainable ‘off the grid’ solution for the museum, using wind and solar energy. Soon we will contact the local power company in order to see if together we can come up with a solution. Gabri Christa, a local dancer but living in the USA, has finished editing her wonderful dancemovie she recorded in January on the Savonet premises, as part of a series on historical buildings (she already brought out a movie recorded in the quarantine building at Caracasbaai). The movie will be premiered in November. This production will become part of the museum’s collection, and will be shown in the section on the architecture of the plantation complex: a very cool and artistic way of showing the ‘before and after’ situation. Well, that’s it for now. We will keep you posted on future developments. 16
