Date Issued:

Summary:
In the Eastern United States, the Florida coastline provides 85% of all nesting sites for the green (Chelonia mydas), leatherback (Dermochelys coriacea), and loggerhead (Caretta caretta) sea turtles. Palm Beach County beaches experience some of the highest nesting frequencies, but recreational use of the beaches has increased threats like raccoon predation. The Gumbo Limbo Nature Center (GLNC) in Boca Raton (founded in 1984) keeps records of nests and predators to the nests. I analyzed 4554 GLNC nest records from 2002-2007 to examine whether raccoon predation of turtle nests was most prevalent in areas of high human impact. I found that raccoon predation occurred at significantly higher rates in areas with public access to the beach than in areas without such access (high access: 50.8%, low access: 14.4%, overall: 36.4%). This suggests the necessity of increased protection of nests in areas of high access for the preservation of nesting populations.
