BACKGROUND
The Gallatin National Forest (GNF) is located in southwestern Montana within the Northern Region (R1)
of the U.S. Forest Service (USFS) and is part of the Greater Yellowstone Ecosystem, the largest intact
ecosystem in the continental United States (Figure 1). The 1.8 million acre Forest contains more than
1,900 miles of fish-bearing streams and 700 high mountain lakes, and supports important, high-profile
recreational fisheries.
