Recovery Plan: Watercress Darter ('Etheostoma nuchale'). (Second Revision).

摘要

The watercress darter is an endangered species known to occur naturally in habitat associated with three springs in Jefferson County, Alabama. The watercress darter also occurs in Tapawingo Springs, Jefferson County, Alabama, where it was successfully transplanted in January 1988. Although not conclusive, limited population survey results indicate an apparent downward trend for all of the naturally occurring populations.
