Dune vegetation would miss a significant source of nutrients if sea turtles go extinct and would not be as stable and not large enough to support the dunes, resulting in increased erosion.

While their range is wide, due to extensive egg collecting and bycatch fisheries, the numbers of leatherback turtles have decreased dramatically over the past century.

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
