In North Carolina, Avissar (2006) found that crabbers relocated their crab pots shoreward into shallow-water areas and tidal marsh creeks to avoid damage to the pots from sea turtles attempting to remove the bait, and Grant (6) noted that capture rates of diamondback terrapin
decreased with distance from shore.

species are also being exported to Asian markets, including Common snapping turtles (Chelydra serpentina), Alligator snapping turtles (Macrochelys temminckii), softshell turtles (Apalone spp.), sliders (Trachemys spp.), Diamondback terrapins
(Malaclemys terrapin), and others (Altherr & Freyer, 2000; Behler, 1997; Williams, 1999).
Wibbels said that the early research efforts showed a population on the brink, a view confirmed in the 2004 Alabama Department of Conservation and Natural Resource's book Alabama Wildlife, in which the Diamondback terrapin
was listed as a highest conservation concern.
Emeric's idea that the expensive amphibians [sic] could be made to flourish on this coast." Emeric apparently returned to California from a trip to the East Coast with five dozen small diamondback terrapins
. These he kept in a "pen of laths in the marsh near San Pablo," and they were eventually "turned loose to populate the marshes."

Although the diamondback terrapin
has not been listed as threatened or endangered in New Jersey, it is considered a species of special concern.
Other studies have concentrated on examining direct impacts of raccoons on prey species in marine coastal environments including eggs of diamondback terrapins
(Malaclemys terrapin Feinberg and Burke, 2003; Butler et al., 2004), spiny-tailed iguanas (Ctenosura similes) (Platt et al., 2000), American crocodiles (Crocodylus acutus) (Fleming et al., 1976; Platt et al., 2000) and sea turtles (Ratnaswamy et al., 1997).
Recent research has indicated that the diamondback terrapin
can represent a keystone predator in its salt marsh habitat (Silliman and Zieman, 2001; Silliman et al., 2005; Gustafson et al., 2006).
I was particularly impressed by Forsberg's 250 original photos of snapping, eastern spiny softshell, eastern mud, common musk, spotted, wood, bog, painted, box, Blanding's, red-bellied cooter, northern map, northern diamondback terrapin
and green sea turtles.
Seventy-eight diamondback terrapin
turtles, each weighing 2-3 pounds, were removed, said a spokesman for airport operator The Port Authority of New York and New Jersey, Reuters reported.
