Status & Trends by Species

Westslope Cutthroat


WDFW

Westslope Cutthroat is a resident fish species, and has been named as a focal species by subbasin planners in 9 subbasins. Status and trends data are available for this species in 2 subbasins. Snapshot data are available in 1 subbasin. 6 subbasins have no data available. Westslope Cutthroat is not a Federally protected species, though it is listed as a "species of concern" in 9 subbasins. No biological objectives have been set for this focal species in the Columbia River Basin.

Westslope Cutthroat Trout are native to both sides of the continental divide in Montana, Idaho, and Canada, with a few scattered populations in Wyoming, Washington and Oregon. Spawning and rearing streams tend to be cold and nutrient poor. Westslope cutthroat trout primarily eat insects and zooplankton and do not grow very large, usually just between 6 and 12 inches.

Focal species represent the fish species that the subbasin planners have identified as focal species for the respective subbasin. The biological objectives associated with a focal species were either described in the subbasin plan or were included in state, tribal, or federal recovery/management plans. Biological objectives and current status are linked to their respective reference information; if the reference exists on-line, a link is provided to the original data.

The status and trend information represents the most current data that is available. Data were collected through interviews with biologists and reviews of reports and websites. Each chart is linked to a table of the data, and each datapoint in that table is linked to reference information. The focal species data presented have been reviewed and approved by the respective collectors.
