Actually a char rather than a trout, the bull trout seeks
out cold streams with ample shelter and clean gravel in Washington,
Oregon, Montana, Idaho, Nevada, and parts of Canada. Since
its habitat requirements are more stringent than those of
many other fish, the bull trout is more sensitive to habitat
alteration. It was listed as a threatened species in 1998.
The greatest risks to bull trout come from logging, roadbuilding,
overharvest and destructive mines like the proposed Rock Creek
Mine in northwestern Montana. This copper and silver mine
would set a terrible precedent by tunneling underneath the
Cabinet Mountains Wilderness Area, degrading habitat for grizzly
bears and lynx as well as bull trout. Hydropower dams throughout
the greater Columbia River basin also have negative impacts
on bull trout.
