|
Prior to 1996, the only known concentrations of Blanding's turtle in Nova Scotia occurred in Kejimkujik National Park and National Historic Site (KNP). In 1996, a campaign based on information posters and surveys was initiated to enlist the public's help in locating turtles in unprotected landscapes. The successful campaign increased the known range of Blanding's turtle in Nova Scotia and helped to identify the first known population outside the Park, at McGowan Lake. Distribution, movements, morphology and reproduction in this population were studied from 1997–2001 by live-trapping, visual sampling and radiotelemetry. This population differs surprisingly from the KNP population: at McGowan Lake most nests occur inland, often on slate outcrops, rather than on lakeshore beaches; nesting effort is apparently increased, with females making a high number of unsuccessful nest attempts; home ranges are small, with dense seasonal aggregations in summer drought refuges and overwintering locations that probably increase vulnerability; adults are smaller and females lay smaller clutches. These differences illustrate that conservation and research must be at an appropriate scale to accommodate local variability of this species in Nova Scotia.
