Sea turtles are considered a keystone species, meaning their presence can have a significant impact on the health and balance of their environment. Here are five ways they contribute:
1. They help keep marine ecosystems in balance.
Different species help control the animals and plants they feed on. Hawksbill turtles eat sponges that can compete with corals for space, while leatherbacks help keep jellyfish populations in check.
2. Nesting turtles help nourish our beaches.
Not every egg will hatch, and not every hatchling will make it to the ocean. The eggs, shells and other organic material left behind provide nutrients that can benefit coastal vegetation and the beach ecosystem.
3. Hatchlings are part of the food web.
Although we want every hatchling to reach the water, they are also an important natural food source for birds, fish and other wildlife. That’s part of the complex coastal food web—and one reason nesting season is so important to so many species.
4. Sea turtles benefit people, too.
Sea turtle conservation supports coastal communities through ecotourism, research, education and wildlife viewing. For many of us, simply seeing a sea turtle in the wild creates a lasting connection to our coast.
5. Green turtles help maintain healthy seagrass beds.
Green sea turtles graze on seagrass, helping maintain healthy seagrass ecosystems that provide habitat and food for many other marine species. Healthy seagrass beds also play an important role in storing carbon.
Here in Nassau County, our nesting beaches are part of this larger coastal ecosystem. Every nest, hatchling and adult turtle contributes to the health and diversity of our coastline.
So the next time you see a sea turtle, or simply see a protected nest on the beach, remember that you’re looking at an important part of a much bigger ecosystem.
