Save Ocean Turtle is a wildlife and conservation photography project, carried out in the state of Sarawak, Borneo, Malaysia.
Sarawak,s first marine national park, Talang Satang was established with the primary aim of conserving Sarawak,s marine turtle population. The park comprises the coastline and sea surrounding four inlands of the southwest coast of Sarawak: Pulau Talang Besar { Greater Taland Island } and Pulau Talang Kecil { Lesser Taland Island } off Sematan, and Pulau Satang Besar { Greater Satang Island } and Pulau Satang Kecil { Lesser Satang Island } off Santubong, near Kuching { Sarawak capital }. These four " turtle Islands " are responsible for 95% of all the turtle landings in Sarawak. The park also includes the Pulau Tukong Ara-Banun Wildlife Sanctuary, two tiny islets which are important nesting sites for colonies of Bridled Terns and Black-Naped Terns.
Talang Satang National Park was gazetted in 1999, and covers a total area of approximately 19.400 hectares { 19.4 sg km }, and comprises all lands below the high tide marks on the respective islands, and the surrounding seas for a radius of 4.8 km from the highest point on each island. Beautiful shallow reef areas surround all the " four islands ". The reefs generally consist of several species of hard coral and colonies of soft coral. They provide shelter and resting grounds for sea turtles, and are also important fish breeding areas.
The islands that make up the Talang Satang National Park are privately owned, the government of Sarawak rents them by paying an economic rent to their owners, to use them as a conservation center for sea turtle.
Pulau Talang Besar is the island where the highest concentration of turtles come to lay their eggs, and it is where I made this photographic report. Located 30 minutes offshore from Sematan in southwest Sarawak. This little island serve as sanctuarie for Green and Hawksbill turtles. Over 90% of turtle landing are from Green Turtles { Chelonia Mydas }. The island are Sarawak,s most important turtle conservation site.
Owing to their small size and fragile environment, the Talang islands have not been developed for tourism. Instead the government,s emphasis has been on turtle conservation.
Sarawak is a pioneer of turtle conservation with Talang Besar being the first site in the world to be the focus of turtle research and management activities. The now common turtle conservation strategies of tagging adult turtles and relocating eggs to hatcheries were first tried out on the small island of Talang Besar.
Conservation work on the Talang islands began in the 1940,s when the Sarawak Museum started a long-tern research project. Data on turtle landings and nests at Talang dates back to 1946. Conservation efforts were accelerated in the 1950,s when turtle eggs were collected from various sites and transferred to a natural beach hatchery on Pulau Taland Besar.
In 1953 a new method of tagging marine turtles was pioneered in the Talang islands when American zoologist John R. Hendrickson came up with the idea of using self-piercing, self clinching cow ear tags. Prior to this it was common for researchers to drill a hole in the turtle and attach a tag with wire. These tags were not very durable and often subject to corrosion. Hendrickson ordered a batch of custom made cow ear tags from a supplier in Kentucky. He then set about tagging as many turtles as possible with the new tags attached to the turtle,s foreflipper. Tom Harrison, the head of the Sarawak Museum, was skeptical of the new approach. In 1956 the first flipper-tagged green turtle landed on Talang Besar to the amazement of Tom Harrison and his wife Barbara who happened to be staying on the island.
Conservation work continues today. Park rangers monitor the beaches, record turtles landings, nests, number of eggs and hatchlings.
Whilst turtles land on the island,s beaches throughout the year, the main turtle nesting season is from April to October. June, July and August are the busiest months with 20 or more turtle landings per night. 2.000-2.500 nests and 150.000-200.000 eggs are recorded on Pulau Talang Besar each year. On average 65% of eggs hatch.
A turtle volunteer programme on Pulau Talang Besar offers visitors the chance to participate in Saawak,s turtle conservation efforts.
Marine turtles are amongst the world,s longest-live creatures, which many reaching a lifespan of more than 100 years. Adult Green turtles grow to 1.5 meters long. The average weight of mature individuals is 68-190 kg, and the average carapace length is 78-112 cm. Exceptional specimens can weigh more than 300 kg. Graceful swimmers that spend most of their time underwater, they have survived almost unchanged since the Triassic period, some 200 million years ago. However the breeding habits that have served them so well for so long are now contributing to their extinction. International Status: Chelonia Mydas { Green Sea Turtle } are listed as Endangered { facing a very high risk of extinction in the wild in the near future } by the International Union for Conservation of Nature Resources in 1982.
Marine turtles mature slowly, only starting to breed between 30 and 50 years of age, and once they commence breeding, females usually only produce eggs once every four of five years. They do not lay their eggs on just any beach, but migrate back to their beach of birth, sometimes across distances of more than 3.000 km. How they find their way back to that particular beach is one of nature,s great unsolved mysteries. It is also a major factor in the decline of turtle population, because as beaches around the world are developed for various purposes, the turtles are unable to move to undisturbed nesting sites.
Other factors that contribute to turtle mortality are deliberate poaching of turtles for meat and tortoiseshell; uncontrolled collecting of turtle eggs { a sea turtle egg is sold in the illegal trade for 3 Malaysian ringgit { about US$0.65 }; entrapment in fishing nets; destruction of feeding grounds such coral reef or sea grass beds; and ingestion of plastic bags which some species mistake for jellyfish, part of their natural diet. Even under perfect conditions, survival rates are very low. A female turtle may lay as many as 10.000 eggs in her lifetime, but because of nesting losses due to natural land predators { on the island of Talang Satang the only predator on land is the Water Monitor Lizard { Varanus Salvator }, which daily comes down to the beach from the edge of the jungle where they live, to detect turtle nests with its excellent olfactory tongue, and dig to eat the eggs }, and predation by fish once they reach the sea, as few as 10 hatchling will survive to reach maturity.
Because of the threat to marine turtles, a conservation programme is under way on Talang Satang,s three larger islands, and also in Tanjung Datu and Similajau National Parks on the Sarawak mainland. Eggs are either removed from nests and placed in guarded hatcheries by Sarawak Forestry rangers. After 40 to 60 days incubation, depending on the temperature of the sand { at higher temperatures it produces more females, and at lower temperatures more males }, young hatchlings are released at nightfall to reduce losses from predators. The programme appears to be working well, as the number of landings has stabilized at between 1.500 to 3.000 per year over a 10 year period, after sinking to an all time low of under 1.000 in the early 1980s.
The conservation programme has been carefully planned to involve local communities. The traditional rights and practices of the local landowners, villagers, and fishermen are recognized, and Sarawak Forestry works in close co-operation with them to ensure sustainable usage of the resources they are entitled to.
Like most protected areas in Sarawak { TPAs } " Totally Protected Areas ". Talang Satang National Park is managed by Sarawak Forestry Corporation { SFC }, what is a statutory body of the Sarawak Government formed under Sarawak Forestry Corporation Ordinance 1995. Which in turn is monitored by the turtle management board { LPP } by its acronym in Malay " Lembaga Pengurusan Penyu ", section belonging to the Sarawak Museum.
