Status: Declining/Stable

Yellowstone cutthroat trout naturally occur in Montana, Wyoming, Utah, Nevada, and the upper Snake River drainage in Idaho and are considered one of the most abundant and broadly distributed cutthroat trout subspecies. Although researchers have estimated that more than 2 million Yellowstone cutthroat trout exist in the Idaho management units, distribution and abundance have been affected by habitat loss/degradation, non-native fish (i.e., rainbow trout, brook trout, and brown trout), and exploitation.
