Implementation of voluntary conservation efforts by the Utah Division of Wildlife Resources and other partners has been crucial to the conservation of the Bonneville cutthroat trout, a fish found primarily in Utah and southwestern Wyoming.

Back in the mid-1990s, Utah, Wyoming, Idaho and Nevada — with assistance from conservation partners — developed several conservation agreements and strategies regarding the Bonneville cutthroat.

Their purpose was to ensure the long-term conservation of Bonneville cutthroat trout by providing guidance on how to eliminate threats and to encourage further conservation actions through interagency coordination.

Since then, the partners who signed the agreements have worked cooperatively to restore, expand and protect Bonneville cutthroat trout in various types of habitat, including multiple-size streams, lakes and reservoirs.

The DWR chairs the rangewide Bonneville Cutthroat Trout Conservation team. Members of the team have undertaken a broad array of conservation activities over the past six years. The team has surveyed and monitored Bonneville cutthroat trout populations; restored, acquired and protected habitat for the trout; removed and controlled nonnative fish; developed brood stock; and worked with federal partners to ensure federal land is managed in a way that protects Bonneville cutthroat trout.

"The restoration of Bonneville cutthroat trout into unoccupied portions of their historic range is one of the most important things the team has accomplished," said Roger Wilson, UDWR sport fisheries coordinator and chairman of the Bonneville Cutthroat Trout Conservation team.

"In the 1950s, Bonneville cutthroat trout were thought to be extinct. Today, through our restoration efforts, Bonneville cutthroat trout now occupy about 35 percent of their historic range in Utah.

"The team's conservation efforts will accelerate over the next several years as we develop additional brood sources and expand our conservation activities."

As a result of these efforts, a federal judge dismissed a lawsuit filed in an effort to list the Bonneville cutthroat on the endangered species list. In dismissing the suit the judge praised the work done by Utah's biologist toward saving the native fish.

Based on voluntary efforts, in 2001 the U.S. Fish and Wildlife Service decided it was not necessary to list the Bonneville cutthroat trout under the Endangered Species Act. A review found that viable, self-sustaining populations of Bonneville cutthroat trout were widely distributed throughout its range and were being restored or protected rangewide.

After the 2001 finding, the Center for Biological Diversity, the Pacific Rivers Council and the Biodiversity Conservation Alliance filed a lawsuit challenging the USFWS's decision.
