Why should we protect turtles?

As with any animal, turtles play an important ecological role in their preferred habitat … the sea. Removal of turtles, through over-exploitation or mismanagement of their environment (including nesting beaches), can have devastating consequences on both the marine ecosystem and all those who rely on it.

Take for example the Green Turtle (Chelonia mydas). Green Turtles are herbivorous and feed on seagrass beds throughout the tropics. This species of turtle is often targeted for its meat, but also caught accidentally in commercial fisheries. Its nesting sites are often destroyed through coastal developments. The species, as with other turtle species, is listed as Endangered on the IUCN’s red list and if we do not take care soon there will be no wild turtles left for our grand children to enjoy.

So why are turtles important?

Green Turtles are one of the few animals that eat sea grass and in are in fact considered keystone species in many areas, as they play a major role in determining the community structure essential in maintaining healthy seagrass beds. Like a normal grass lawn on land, seas grass beds need to be constantly cut short to keep healthy. Cropping by hungry Green turtles, allows the sea grass to spread across the sea floor rather than just getting longer and older grass blades. The fresh young leaves from cropped plants, have a high nutritional value and support a wide range of other smaller herbivorous animals, which are eaten by bigger carnivorous fish, which are in turn eaten by humans.

As seagrass beds are vital breeding and nursery grounds for many species of fish, shellfish and crustaceans (many of which are commercially exploited), if these animals cannot breed successfully, and their young are unable to develop an mature, their populations will eventually decline.

As the populations of commercial species decline, fishermen are unable to meet demand for fish, shellfish and crustaceans. People who rely on these as their staple diet either starve or may take to crime to make ends meet.

As many coastal areas also rely on tourism, when the crime rates go up, the tourist stay away leading to loss of jobs and even more hardship for coastal communities which eventually impact people living further inland.

Indeed the question really is, why shouldn’t we protect turtles?

Turtles have existed for over 100 million years, travelling unhindered throughout the world's oceans. Today, they are struggling to survive, mainly because of things people are doing to the oceans and beaches. It is possible that a world in which turtles continue to die in large numbers, may soon become a world in which humans struggle to survive.

If, however, we learn from our mistakes and begin changing our behavior, there is still time to save turtles from extinction. In the process, we will not only be saving one of the world’s most mysterious creatures, a survivor from the age of the dinosaurs, we might just be saving ourselves too!

Happy Anniversary Carol!!

December 20th is the one year anniversary of Carol receiving her satellite-relayed GPS tag which may not sound like a lot but in terms of satellite tracking this is a pretty impressive achievement!

Carol was tagged on one of the prime nesting beaches on the South of Mahe in a programme organised and implemented by MCSS in association with the Ministry of Environment and the Wildlife Clubs of Seychelles and funded by Barclays Bank Seychelles (See Post 2). This innovative programme was aimed at increasing public awareness of Seychelles turtles through a programme that integrated hi-tec turtle research into the activities of the schools and Wildlife Clubs as well as through several competitions including an art contest and a science-project contest. It was through one of these awareness competitions that Carol named by Jessica Marengo, the winner of the ‘name-the-turtle competition.

Since being tagged Carol has been tracked on-line through the facilities of and the track information was shared with teachers at local schools via the Wildlife Clubs who developed a number of science projects based on her track (See Post 13). The pupils and research staff watched in surprise as Carol moved away from Seychelles at the end of her nesting season and migrated away towards North West Madagascar arriving at her apparent chosen feeding ground on April 27th where she has remained, apparently quite contentedly, to this day (see the side bar for the latest tracking maps).

During her migration Carol has continued to surprise the research team with her impressive diving abilities with numerous dives made to depths of over 100 metres, not bad for an air-breathing turtle!

Today on her Anniversary Carol is still foraging off the Mitsio islands with her satellite tag sending us daily messages of where she is and what activities she has been up to. How long her tag’s batteries will last is now a sensitive question; originally the calculations indicated about three months as the fast-loc GPS is fairly power hungry, but having now achieved 12 months we can only keep our fingers crossed!

So a big thank you to all those involved in this tagging programme and our Best Wishes to Carol for the coming year!!

Meet the Turtle Officers from Banyan Tree Resort

In 2003, MCSS launched its Nesting Turtle Monitoring Programme in the South of Mahé with funding from the Banyan Tree Resort’s Green Imperative Fund. In November 2004, a training session which included a practical session on how to tag a nesting turtle was organised for Banyan Tree staff in collaboration with Dr Jeanne Mortimer, Turtle Consultant. After which, annual refresher courses where carried out by MCSS Research Officer, Elke Talma, at the beginning of the turtle nesting season in 2005, 2006, 2007 and more recently, on the 25th of September 2008.With the recent launch of the MCSS turtle blog, we have asked the 2008 Turtle Officers from Banyan Tree Resort to introduce themselves:

Hi, my name is Adam Abdulla from Maldives, and I have worked at Banyan Tree Resort, Seychelles at Intendance beach on Mah̩ island as a coconut tree climber for almost five years. In 2003, I began assisting with the MCSS РBanyan Tree Turtle Monitoring Programme and in 2004 was taught how to tag nesting turtles by Dr Jeanne Mortimer. I have also attended the annual refresher training sessions organised by Elke.

During the nesting season, I come to work early and walk the beach in search for nesting turtles. If I am lucky enough to see one, I sit with her until she finishes laying – usually surrounded by a group of exited tourists from the Resort. As she makes her way back down the beach, I will measure and tag her and pass all the information I have gathered on to Elke. Over the years, Elke and I have become good friends and I enjoy working with her – even when she gets a bit bossy!

While I enjoy seeing nesting turtles, I prefer releasing hatchlings because seeing them heading out into the wide open sea, makes me realise that I have done my bit to accomplished my personal mission towards environmental protection.

Hi, my name is Danny Bibi and I have been working at Banyan Tree Resort, Seychelles since 2001 as a gardener. In 2004, I began assisting with the MCSS – Banyan Tree Turtle Monitoring Programme. In 2005, I formally joined the Turtle Monitoring Team after attending training with Elke.

Over the years, I have seen turtles tagged by Adam and Elke return to Intendance beach to nest again. I am hoping that eventually, one of “my” turtles will return! I find this extremely satisfying, as its shows there is hope for the future. With any luck (… and a lot of dedication), my grandchildren can appreciate what many take for granted today.

Growing up in Seychelles, I use to eat turtle meat but since working with the Turtle programme I have stopped this bad habit. I like working with Elke as she is someone you can trust and always has a smile on her face.

Hi, my name is Paul Isaac and I am a Garden Supervisor at Banyan Tree Resort, Seychelles. I have worked at Banyan Tree for seven years now and in 2006 began assisting with the Turtle programme. I formally joined the Turtle Monitoring Team in 2008, after attending training with Elke.

I like being part of the Turtle Team as I want to protect turtles so that my kids will be able to see a nesting turtle someday. The information I collect, is important because it allows us to track turtle movements both during and between nesting seasons. So far, we know that most turtle come back to Banyan Tree to nest but every now and again one of our turtles is spotted by Elke, nesting on a neighbouring beach.

I am always thinking about the future, which is why I enjoy releasing turtle hatchlings. It is gratifying to see then crawling down the beach, determined to make their mark on the world.

Hi, my name is Christophe Belle. I am a Seychellois and began working at Banyan Tree Resort, Seychelles in June 2007 as a gardener. In September 2007, I joined the Turtle Team after attending training with Elke. In December, I also volunteered to manage the Wetlands at Banyan Tree and share my time between turtles and terrapins.

Whenever is see a nesting turtle, I make sure I report the sighting. While I am not authorised to tag turtles (Elke is very strict with her training and thinks I should spend more time on the beach and less time in the wetlands!), I know that the information I collect will help us better understand and therefore, protect our turtles.

Although it is important to protect turtles, it is just as important to protect their nesting sites because without the nesting beaches, turtles will eventually go extinct.

Legal harvest of turtles...

In times past, when Seychelles was a young nation and there was no fillet steak from Brazil, turkey from South Africa or leg of lamb from New Zealand, you ate fish which was in abundance. Most families kept some chickens, not so much to eat but for the eggs which were sold to supplement the family income. Life was hard then and to come across a turtle whilst fishing or on the beach was cause for celebration for it was red meat with a capitol M, a welcome addition to the diet.

The turtle season was anticipated, as we now anticipate Christmas, since there was money to be had. Green turtles were killed for eating and Hawksbill turtles for their shell, which was sold and made into trinkets like spectacle frames combs, guitar picks and cuff links.

On the outer islands fishermen were employed to catch fish for the workers and fish for salting. Occasionally a turtle would be killed and the meat divided, a portion going to each worker as part of his food ration. Sometimes they would upturn the carapace on the barbecue or fire, seasoning the meat inside with spices. Then when cooked, all would sit around the carapace with their bread and eating irons helping themselves to the feast.

Turtle were also harpooned, to be shipped to Mahe. Their wound would be plugged and they would be sent to the Old Pier where there was a turtle park….a pond where they were kept. On a Saturday a couple would be slaughtered and their meat sold in the market.

This happened not centuries ago, but in living memory.

Most of our older generation will have eaten and enjoyed turtle meat but that was in another time. It was a time when tigers were hunted for trophies and to go on a safari shoot meant you go with guns and not cameras, a time when fur coats were made of real fur and not fun fur. That time is gone. Now we are reaping the bitter harvest of our past excesses.Turtles are now so few in numbers that all of the turtle species are endangered or critically endangered.
