Due to coastal development and sea level rise, sandy beaches in Florida, USA are disappearing due to coastal squeeze. This is a cause for concern for wildlife such as sea turtles, which use the habitat for nesting. Solutions include beach nourishment (sand placement) and beach armoring (stabilization structures), both of which have the potential to impact sea turtle nesting and long-term beach stability. As an alternative to the more traditional hardening structures (such as seawalls), a third option, a geotextile tube (geocore) system can be buried to promote a “natural” dune system. However, research on how these structures may impact sea turtles is scarce. Loggerhead sea turtles (Caretta caretta) emerge at night to lay their eggs on the sandy beach. A nesting female can abandon her nesting attempt (i.e., false crawl) due to a variety of factors such as the beach slope, sand quality, or disturbance by human presence, lighting, or obstacles. False crawls can waste precious energy reserves that could be used for reproduction. Once eggs are deposited in the sand, they are at the mercy of the local microhabitat for the duration of their incubation. Thus, beach quality is crucial for the development of successful hatchlings. The goal of this study was to investigate how the presence of stabilization structures installed on Casey Key, Florida impacts loggerhead nesting. We aim to compare the nesting success (ratio of nests to false crawls) at a natural control site, a geocore site, and site with a seawall. Furthermore, we will investigate loggerhead hatching and emergence success at each site.
