SALT LAKE CITY -- The U.S. Forest Service wants to use a poison in southern Utah to kill hundreds of nonnative trout so that native fish can be restored.
Crews began that work last fall but local officials in the Boulder area raised concerns about the poison's effect on water quality and biodiversity.
In response, the Dixie National Forest is starting an environmental review of the proposal for about eight miles of the east fork of Boulder Creek. If approved, the poisoning could begin later this year. Once the brook trout and other nonnatives are killed, portions of the creek would be stocked with native Colorado River cutthroat trout.
State wildlife biologists say the chemical poison proposed for the project has been used for decades without adverse long-term effects.
