Brook trout are a non-native trout introduced in the late 1800's to duplicate their popularity in the eastern United States. Like bull trout, brook trout are char and spawn in the fall. Brook trout hybridize with native bull trout, and may also be a threat to native cutthroat and rainbow trout because of their highly aggressive nature and slightly larger size as fry.

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.
