Response Statement - Northern Map Turtle
There have been no quantitative, long-term studies of this species in Canada and, therefore, there is limited evidence of recent declines, range contraction or local extirpation of the species. However, the species’ long-lived life history with delayed age of maturity and the potential threats to its habitat suggest that it is susceptible to population decline. Significant threats include direct mortality from collisions with motor boats and from commercial fisheries bycatch. Loss and degradation of shoreline habitat is another threat because this wary turtle is readily disturbed by human activity and boating, and shoreline developments interfere with the species’ basking and nesting behaviour. Unnaturally high predation of nests by mammalian predators, especially raccoons, is another threat. If not ameliorated, these threats combined with the species’ life history will cause the species to become Threatened in Canada.
