Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Restore or maintain beaches (‘beach nourishment’) Three studies evaluated the effects of restoring or maintaining beaches on reptile populations. All three studies were in the USA. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (3 STUDIES) Abundance (1 study): One replicated, site comparison study in the USA found that gopher tortoise densities were higher and numbers occupying burrows similar on constructed sand dunes compared to natural dunes. Reproductive success (2 studies): Two controlled, before-and-after studies in the USA found that one year after adding sand to beaches, nesting activity decreased more for loggerhead turtles, and loggerhead and green turtles compared to on unmodified beaches. Two years after nourishment, both studies found that loggerhead nesting activity had increased, and in one study nesting had returned to pre-nourishment levels. BEHAVIOUR (2 STUDIES) Use (1 study): One replicated, site comparison study in the USA found that burrows on a constructed dune were discovered by gopher tortoises after three months. Behaviour change (1 study): One controlled, before-and-after study in the USA found that one year after adding sand to beaches, loggerhead turtles made more non-nesting crawls than on unmodified beaches, but the difference was smaller two years after nourishment.

Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts.
