Île Plate in Focus: A Year of Progress with ICS

26/8/2025

0 Comments

 
On August 8th, a team from the Island Conservation Society’s Head Office at Pointe Larue, along with members of the Plate Foundation, visited Île Plate to launch a new conservation initiative. They were joined by the island’s first permanent conservation team, marking the beginning of a promising chapter for conservation on another island managed by the Islands Development Company (IDC). This effort was made possible through collaboration with key stakeholders, including the Waldorf Astoria Hotel and the Department of Environment in the Ministry of Agriculture, Climate Change and Environment.
One year later, the team has celebrated several conservation milestones and continues to build on its early successes.

Turtle Monitoring
A total of 438 Hawksbill turtle nests were recorded and of which 70 were tagged.  Ongoing monitoring of Green turtles has also been close to record-breaking, with 46 nests documented and 7 individuals tagged. The data collected so far has made Ile Plate one of the most important nesting areas for sea turtles in Seychelles.

Marine Monitoring
Monitoring of the lagoon around Ile Plate has been very interesting, with an abundance of marine life recorded, including five species of rays and two species of sharks. The team has expanded their monitoring into seagrass and other marine life, highlighting the ecological importance of the lagoon surrounding Île Plate.

Bird Observations
Before their arrival on Ile Plate, data on birds were sparse for Ile Plate. In the last year, the team has recorded 42 bird species frequenting the island. Amongst the most important discoveries was a Red-tailed tropicbird that nested successfully on the island, and a small colony of wedge-tailed shearwaters, which will now be part of continued monitoring and possible future conservation initiatives.

Challenges and the Way Forward
Marine Debris
Due to Île Plate’s proximity to Mahé and its extensive lagoon, marine debris remains a major concern. Through regular beach patrols, the team have collected an astounding 505.55 kilograms of debris over the past year, comprising mainly of plastic bottles and fishery-related waste.

Invasive Alien Species
The presence of invasive species poses a threat to the island’s ecosystem. The most prominent is the Castor oil plant, which contains the toxin Ricin which is poisonous to most animals including humans. The removal of this invasive species has been actively targeted. So far, 6,723 square meters have been cleared, and 4.72 kilograms of seeds have been collected to prevent regrowth.  Another challenge has been the presence of rats, feral cats, and chickens. ICS has added a dedicated eradicator to its conservation team to address this issue on Ile Plate. So far, 26 feral cats and over 212 chickens have been removed to reduce pressure on native wildlife.

Looking Ahead
Through their Centre on Ile Plate, ICS is offering visitors a rare opportunity to engage directly with conservation through hands-on participation. Expanding beyond marine and avian monitoring, ICS is now launching programs to explore lesser-studied aspects of the island’s biodiversity, such as conducting inventories of reptiles and native plant species. 
​
These projects may be small, but they are meaningful victories for conservation on Île Plate. Each new project contributes to a growing understanding of the island’s unique ecosystem and helps restore its natural balance. While many unknowns remain, the presence of a permanent conservation team offers hope for continued progress and the development of a comprehensive database of species and habitats that need protection.

Monitoring the Translocation Successes of Aride Island’s giant tortoises

26/8/2025

0 Comments

 
For three months, I lived on Aride Island, a haven for wildlife in the Indian Ocean, where seabirds rule the skies and giant tortoises slowly roam on the forest floor. Aride Island offered me a rare opportunity to immerse myself in nature and spend my days studying and living alongside the iconic Aldabra giant tortoise.
My Research
My project focused on understanding the feeding preferences and behaviour of Aldabra giant tortoises, both wild-raised and captive-raised. Aride has a small population of these gentle giants that had been roaming free on the islands for a few years, and a recent translocation of juvenile tortoises that had been raised in captivity to the island provided the ideal subjects for my research. For my project, I used a combination of observational surveys, dung analysis, and controlled feeding choice experiments to get a comprehensive picture of what these gentle herbivores were eating and how they were influencing the ecosystem.

Any potential differences in feeding preferences between the two groups would have important consequences for the seed dispersal of native plant species on the island (including the Indian-Almond and endemic Wright’s Gardenia). Therefore, the results of this study could inform future reintroduction efforts of the Aldabra giant tortoise on Aride and other islands.

Living on Aride
Living in such proximity to wildlife was one of the most rewarding—and sometimes surprising—parts of my time on Aride. I shared space with skinks in the kitchen, watched seabirds raise their chicks just metres from my bedroom, and frequently had to pause data collection for a stubborn tortoise refusing to approach any of the food items offered up during a feeding experiment. With no distractions from modern life, I learned to slow down, observe more deeply, and appreciate the complex dynamics of this fragile ecosystem.

Gazing into the ancient, weathered face of a giant tortoise felt like looking back in time. Their deeply wrinkled skin and deliberate, unhurried movements through the forest carried an unmistakable echo of the Jurassic era. Each tortoise had its distinct personality, some were shy whilst others were bold, and over my weeks on Aride, I came to know each of them individually.

The one tortoise that stood out from the very beginning was a remarkably spirited male known on the island as T-Rex. True to his name, T-Rex was the most fearless and charismatic of the group. While most tortoises would hiss and retreat into their shells at the sight of a human, T-Rex would march straight up to visitors, expectantly leaning in for scratches. His confidence and curiosity made him a constant presence, and by the time I left Aride, it felt like he had left just as much of a mark on me, as I had on him.

Aside from tortoises, as part of my research, I also had to learn to identify the flora found on Aride. This gave me a deep appreciation of the beautiful plant life found on Aride and across the Seychelles. I am especially going to miss wandering beneath the towering, crimson-leaved Indian-Almond trees on the coastal plateaux, and amongst the forests of endemic Wright’s Gardenia on the East hill. A highlight of the three months was being able to experience the Wright’s Gardenia in flower for the short few days that this occurs yearly.

Beyond my time on Aride, weekly shopping trips to Praslin gave me the chance to enjoy the delicious food from the reggae bar in Grande Anse every Friday. It was here that I developed a love for creole food, especially fish coconut curry, which may be the thing I miss most from the Seychelles!
However, it was the small community of people living on Aride that really made my time on the island. Whether it was one of the incredible fish BBQs Steve provided for us, or the support the island’s conservation officers, Emma and Maria, provided at the beginning of my data collection, I was made to feel welcome on the island and part of the community.

To Future Researchers
To future researchers and volunteers who are fortunate enough to spend time on Aride, my strongest recommendation would be to take the time to explore the island and fully embrace the stillness and peace that it offers. Aride is one of the rare places left on Earth where the natural world remains largely undisturbed, and thus where you can truly feel what it means to be immersed in the wild.

Unrecorded Hawk-Moth Appears on Desroches

4/8/2025

A previously unrecorded species of hawk-moth (family Sphingidae) has been spotted for the first time in recent months on Desroches Island.

​This hawk-moth is believed to belong to the genus Macroglossum, and its discovery may represent either a new species or one known from elsewhere, but that has until now gone unnoticed in Seychelles. Insects on Desroches have been recorded opportunistically since 2024, when a new team with an interest in entomology arrived on the island.
According to the ICS Conservation Officer, Lisa Wareing, the insect of their interest seemed to have been on the island for a while since a thriving population, with multiple females, has been identified and seen actively laying eggs. Interestingly, all sightings have so far been of females, with most found on the Noni plant (Morinda citrifolia), on which they lay their eggs. When and on which plant the adults feed on is as yet unknown, leaving more work for the team to do. 

“The caterpillars can vary in colour, with some being bright green while others are black. They also have or grow a long tail,” describes Wareing, referring to the horned larvae common to the species. The adults’ behaviour in feeding during the daytime is in contrast to most other moth species on the island, which is what made it first stand out. The adult is dark brown, with orange patches on the underwing. It only seems to fly in low light around dawn and dusk, which makes it difficult to find.

To help clarify its identity, the ICS team has reared caterpillars and documented every stage of the development. They have also collected specimens of those that hatch, which have been preserved and will be sent to international laboratories and other colleagues for identification.
​

This unexpected discovery has added a new dimension to the conservation efforts on Desroches Island, as well as other islands where ICS has a permanent presence. Desroches is known for its giant tortoises; however, the island’s smallest inhabitants also deserve attention. A new species of wasp for Seychelles has also been found by the team, which shows the potential for further research. Studying moths may not be every conservationist's interest, but this is a sure sign that there are many more things to be discovered by science, especially when it comes to insects. ​
