Peripheral species are those that are at the edge of their range, often barely crossing the line into a political jurisdiction. Formerly, the process for listing species in British Columbia prevented peripheral species from becoming candidates for threatened and endangered status. Reasons for changing this policy include patterns of species collapse, historical importance of peripheral species in recovery planning, and genetic, evolutionary, and biodiversity considerations.
