Assessment Summary – November 2008 Common name Snapping Turtle Scientific name Chelydra serpentina Status Special Concern Reason for designation Although this species is widespread and still somewhat abundant, its life history (late maturity, great longevity, low recruitment, lack of density-dependent responses) and its dependence on long warm summers to complete incubation successfully make it unusually susceptible to anthropogenic threats. When these threats cause even apparently minor increases in mortality of adults, populations are likely to decline as long as these mortality increases persist. There are several such threats and their impacts are additive. Aboriginal Traditional Knowledge generally supports the declining trend and population figures in the COSEWIC report. Occurrence Saskatchewan, Manitoba, Ontario, Quebec, New Brunswick, Nova Scotia Status history Designated Special Concern in November 2008. Assessment based on a new status report.
