Pecos Pupfish (Cyprinodon pecosensis) Listing Proposal Withdrawn

In 1998, the Service proposed to list the Pecos pupfish, a small fish
native to the Pecos River, its tributaries, and nearby waters in New Mexico
and Texas, as an endangered species. The threats cited in the proposal
were 1) habitat alteration resulting from dams, water diversions, and
excessive groundwater pumping, and 2) hybridization with a non-native fish
species, the sheepshead minnow (Cyprinodon variegatus), which anglers
introduced into the pupfish's habitat in the 1980s as a baitfish. Since
publication of the listing proposal, the Service and other federal and
state resource management agencies have executed a Conservation Agreement
that addresses the threats to the pupfish and establishes a plan to
restore the species to a viable status. For that reason, the Service
published a notice in the March 17, 2000, Federal Register withdrawing the
listing proposal.
