Malaclemys terrapin The Poplar Island Environmental Restoration Project (PIERP) is a 475 hectare reconstruction of Poplar Island which had eroded into Chesapeake Bay. The goal of the PIERP is to use dredged material to rebuild the island and provide suitable wildlife habitat for both wetland and upland species. After the completion of the perimeter dike in 2002, diamondback terrapins (Malaclemys terrapin) began nesting on the PIERP and I initiated monitoring of terrapin nesting and nest success. Nesting activity and recruitment has increased from 69 nests in 2002 to a peak of 282 in 2005. Nest success on the PIERP is high compared to mainland nesting areas because the primary nest predators, raccoons and foxes, are removed. The high nest success on the PIERP has resulted in a better understanding of the proportion of nests over-wintering in the Chesapeake region allowing us to compare nest survivorship and hatchling energetics of fall and spring emerging hatchlings. Furthermore, we have marked over 3000 hatchlings and released them into the PIERP wetlands in anticipation of determining younger age class survivorship. I will summarize our monitoring trends and discuss how the PIERP may serve as a model for future restoration of turtle habitat.
