The introduction of exotic species
Exotic species are those that are not native to a specific habitat but are introduced to it. The introduction of exotic plant species in the nesting areas can cause problems to the sea turtles. Exotic plant species that grow rapidly will outcompete the native plants and invade the nesting locations. Furthermore, the plant roots might also be a problem as they destroy the nests and cause high egg mortality.
The introduction of exotic marine species such as algae and animals poses another type of problem which can have devastating consequences in foraging grounds. These exotic marine species might prevent coral growth and reproduction, affecting the availability of food for some species of sea turtles as well as other animals which depend on this type of habitat. When algae invade fish burrows or the places where the turtles usually rest and take cover, this invasion leads to a decrease in the amount of food available.
