Species of Special Concern

A species of special concern is any species of fish or wildlife that does not meet the criteria of an endangered or threatened species but is particularly vulnerable, and could easily become, an endangered, threatened, or extirpated species due to restricted distribution, low or declining numbers, specialized habitat needs or limits, or other factors. Special concern species are established by policy, not by regulation, and are used for planning and informational purposes; they do not have the legal weight of endangered and threatened species. The Maine Department of Inland Fisheries and Wildlife reviews the list of special concern species at the beginning of each calendar year, and, based on criteria in the Maine Endangered and Threatened Species Listing Handbook (PDF), revises the list as appropriate.
