Population studies can contribute essential information to the management of rare and endangered species. Such studies have been critical for understanding special life histories and for planning appropriate conservation and management methods for the special needs of individual species. This is especially true for turtles, due to the fact that they are exceptionally long-lived. Diamondback terrapins (Malaclemys terrapin) are medium-sized turtles that occur in estuarine habitats along the North American east coast from Cape Cod, Massachusetts to the Gulf Coast of Texas (Butler et al. 2006). Information on the status of Diamondback terrapins is patchy throughout their range and many isolated populations may be suffering declines. This study examines the status of nesting diamondback terrapins (Malaclemys terrapin) in Jamaica Bay, New York, during the summer of 2009. Jamaica Bay is an estuary located on the eastern edge of the Hudson River Bight, where studies on terrapin nesting ecology have been ongoing since 1998. Between the months of June and July, data were collected on 383 female terrapins on the main nesting habitat on the island of Ruler’s Bar Hassock. Seventy three per cent of these terrapins had been captured before. All captured female terrapins were reproductively mature and the majority of females sampled ranged from170-180 mm SPL. Data collected during 2009 were compared with data from previous years. This is the first study of this kind for this population where demographic data were analyzed in order to understand the structure and status of M. terrapin in Jamaica Bay.
