Species at the Edge: The Case for Listing of "Peripheral" Species
... Peripheral taxa are those that are at the edge of their range, usually those that barely extend into a political jurisdiction. Since the late 1980s, British Columbia has risk-listed species of vertebrates, with Red-listed species being of the greatest conservation concern, followed by Blue-listed, a ...
