Seagrass beds around the island have decreased drastically, probably ripped off by the strong current or covered by sediment, it could be a potential problem for sea turtles and other marine life which depend on it as a food source. Mainly the invasive midrib seagrass (Halophila stipulacea) disappeared; native seagrass species survived the storm more often, such as turtle grass (Thalassia testudinum) and manatee grass (Syringodium filiforme), probably due to their larger growth form and strong roots.
Fortunately several marine species were found in good health on our reefs, including sharks, stingrays, sea turtles, reef fish, octopus and morays. The Nature Foundation is very pleased to have recorded quite a lot of sea turtles surviving the hurricane. Interesting is the occurrence of sharks on our reefs, three weeks after the storm no sharks were recorded yet, however four weeks after the storm sharks were back to normal abundance. This shows that sharks are most likely looking for hurricane shelter in the deeper waters and after return to their normal habitat.
Despite the reef and coral damage, St Maarten dive sites are still great for scuba diving because of the remarkable marine life and surroundings. The Foundation still highly recommends St Maarten as a dive destination and encourages visitors to return to scuba dive. The Nature Foundation is aware of three dive boats surviving the storm and dive schools are encouraged to start operating in the near future.
