| Abstract |
|
Poplar Island Environmental Restoration Project is a unique solution for the dredge material placement and restoring decreasing habitat in the Chesapeake Bay. Since 2002, a long-term terrapin monitoring program has been documenting diamondback terrapin, Malaclemys terrapin habitat use. Northern diamondback terrapins, hatchlings may either emerge from their nest in the fall and seek other overwintering hibernacula, or remain inside their natal nest to emerge the following spring, known as delayed emergence. Results from the 2007-08 nesting season found that compaction and the presence of ice nucleating agents (as a measure of crystallization temperature) affected nest emergence timing in hatchlings. Fall emerged nests had lower bulk density (less compacted) and had a higher potency of ice nucleating agents compared to spring emerging nests. With proper management, areas such as Poplar Island may become areas of concentration for terrapins and thus provide a source population for the terrapin recovery throughout the Bay.
