Field estimates of the abundance of two trout species (bull trout and westslope cutthroat trout) in Montana and rainbow trout in Washington and British Columbia were collected in concert with environmental DNA samples (eDNA) to evaluate if eDNA copy numbers correlated with abundance of trout. In addition, stream habitat data including channel units (pools, riffles), substrate, large woody debris, among others, were collected at sites.
The dataset includes measurements of stream habitat, fish abundance of westslope cutthroat trout and bull trout, and species-specific measures of environmental DNA (eDNA) from within the water. The data covers multiple streams in western Montana.
Officially designated as Montana's state fish, the Westslope Cutthroat's historical range included all of Montana west of the Continental Divide, as well as the upper Missouri River drainage. The average size of these fish is 6 to 16 inches, depending on habitat. It is often difficult to distinguish the westslope from other cutthroat species, but it tends to have more small spots by the tail and none by the pectoral fin. Also, the Westslope Cutthroat Trout is more of a silvery or greenish color than other cutthroats.
