Denver, Co – Four conservation groups today sued the U-S Fish and Wildlife Service. They want the Yellowstone cutthroat trout listed as a threatened or endangered species.
Plaintiffs are the Center for Biological Diversity, Biodiversity Conservation Alliance, Ecology Center, and Pacific Rivers Council.
The lawsuit was filed in U-S District Court in Denver.
Plaintiffs say the Yellowstone cutthroat trout is beset by non-native trout, habitat degradation, fragmenting of the trout population and disease.
The federal agency rejected the listing in 2001. It said the number of Yellowstone cutthroat trout has declined from historic levels; but there are viable, self-sustaining populations, that are widely distributed throughout the fish's historic range.
Yellowstone cutthroat trout are found in about 47-hundred miles of stream in Montana, Wyoming and Idaho; and in about a thousand miles of stream in Yellowstone National Park.
