Watercress Darter National Wildlife Refuge
Watercress Darter National Wildlife Refuge is a 23 acre National Wildlife Refuge around Thomas Spring, which is within the city limits of Bessemer, created exclusively to protect the endangered watercress darter. It is the smallest National Wildlife Refuge in the United States. The facility is unstaffed, but is administered by the Mountain Longleaf National Wildlife Refuge in Anniston and monitored by volunteers. Sarah Clardy is manager of both those refuges.
The refuge is open to the public and offers limited opportunities for hiking and wildlife photography. Fishing is not permitted on the refuge for the protection of the watercress darter.
Watercress darters were first found in Thomas Spring in 1976, which was then private property. It was the first population found since the species' discovery in Glenn Spring in 1964. Thomas Spring had been dammed approximately 20 years earlier, producing a pond that was an ideal habitat for the fish. In 1977 the land owner introduced grass carp to clear the spring of vegetation, which they had mostly done by October. During this time, sampling collected only one darter.
On October 1, 1980, the U.S. Fish & Wildlife Service purchased 7 acres of property around Thomas Spring exclusively to protect the watercress darter. The main feature of the refuge is a quarter-acre pond along the spring which is essential to the survival of the fish. After establishment, the grass carp were removed and, in early 1981, the spring was re-vegetated. Shortly thereafter, the refuge was restocked with darters from Glenn Springs.
