Protect habitat: Sea turtles
A before-and-after study in 1988–2004 on three beaches in Costa Rica (Santidrián Tomillo et al. 2007) found that six years after a national park was created, numbers of nesting female leatherback turtles Dermochelys coriacea tended to be lower and hatchling numbers tended to be higher than before the park was created. Results were not statistically tested. In the six nesting seasons after a national park was created, 68–1,000 female leatherback turtles nested/year and 15,734–153,547 hatchlings/year were produced, compared to 732–1,504 nesting female leatherback turtles and 30,180–30,788 hatchlings/year in the three years before the park’s creation. The park was declared in 1991 and comprises three beaches. An unspecified number of nests were relocated due to threat of tidal inundation. Nesting female numbers were based on counting depressions left in the sand by nesting turtles.
