Executive Summary

The Bitterroot, Flathead and Lolo National Forests have conducted baseline bull trout risk assessments finding the majority of the sub-watersheds assessed are at risk from the effects of existing roads.

The Bitterroot found that, due to existing road densities and road locations, only 36% of the sub-watersheds assessed continue to Function Appropriately, while 64% are found to be either Functioning at Risk or Functioning at Unacceptable Risk.

The Flathead found that, due to existing road densities and road locations, only 30% of the sub-watersheds assessed continue to Function Appropriately, while 70% are found to be either Functioning at Risk or Functioning at Unacceptable Risk.

The Lolo found that, due to existing road densities and road locations, only 12% of the sub-watersheds assessed continue to Function Appropriately, while 88% are found to be either Functioning at Risk or Functioning at Unacceptable Risk.

Road reclamation is found necessary to restore appropriate function to watersheds damaged by roads.
