Malaclemys terrapin Throughout the diamondback terrapin’s range, Louisiana likely holds the most available habitat of any other state for the species (approximately 6500 km2 of brackish/saline marshes), yet little is known about terrapin distribution and abundance throughout coastal Louisiana. Most terrapin records have come from the southeastern coastal marshes, while few are known from southwestern Louisiana; for the latter, the most recent specimen or published records date back to the 1970s. Therefore, we wanted to determine if (1) terrapin populations persist in historical collection localities and (2) determine if terrapin populations are present in new coastal marsh localities of southwestern Louisiana. We sampled for diamondback terrapins during 2011-2013 and targeted marshes near historical collection localities, as well as other apparently suitable brackish and saline marshes. We used unbaited fyke nets with 7.6 and 15.2 m leads to capture terrapins, as well as manually searching tidal ponds by airboat. Terrapins were captured at almost all sites, with terrapin abundance varying considerably across sites. Several sample sites would be classified as having “locally abundant” and demographically stable terrapin populations; at other sites we collected a smaller number of individuals with unknown population viability. In summation, all sites with terrapin captures represent either (1) a new locality for terrapins or (2) the first record in over 40 years for that locality. Terrapin sampling in southwestern Louisiana will continue in these locations to further delineate population densities and terrapin life history.
