District 200, Montana

Steep, heavily timbered mountain terrain; elevation spans roughly 3,000 feet along the Clark Fork River corridor to approximately 7,500 feet at higher ridges. The district is bisected by I-90 and the Clark Fork River, which create both access corridors and wildlife barriers. South-facing slopes at lower elevations provide winter range for elk. Approximately 80% of the area has slopes at or below 30 degrees, with rugged drainages throughout.

Public land comprises approximately 91% of the district (approximately 84% USFS administered by the Lolo National Forest Superior Ranger District, 7% state land); private land (~9%) is concentrated in river bottoms and is primarily residential with some agricultural use. The legal boundary runs from the junction of US Highway 93 and US Highway 12 at Lolo, west along US Highway 12 to Lolo Pass and the Montana-Idaho border, then northwest along the state border crossing I-90 at Lookout Pass to the Mineral-Sanders County line (C-C Divide), then east and south along the C-C Divide to USFS Trail 404 near Combest Peak, east on Trail 404 to the Miller Creek Loop USFS Road 7592, east along Road 7592 to its junction with USFS Trail 1714, south on Trail 1714 to Cascade Campground on the Clark Fork River, then south across the Clark Fork via USFS Trail 242 to USFS Road 97. Primary vehicle access corridors include I-90 (Lookout Pass to the St. Regis area) and US Highway 12 along the Clark Fork. Hundreds of Forest Service roads provide road access throughout the district, though some are subject to seasonal closures or motorized/nonmotorized restrictions. Numerous USFS trails supplement road access into the interior. Approximately 940 acres of private land in the district have historically been enrolled in FWP's Block Management Program. No designated Wilderness areas are present within this district. I-90 presents a significant physical barrier to wildlife movement and creates wildlife-vehicle collision hazards at low-elevation crossing points.

Dominated by dense conifer forest — primarily lodgepole pine, Douglas-fir, and spruce-fir at higher elevations, with ponderosa pine on lower south-facing slopes and dry ridges. River bottoms along the Clark Fork and St. Regis River support riparian cottonwood and willow habitat. Some areas experienced severe stand-replacement fires leaving extensive blowdown, while other portions have seen very little disturbance since the 1910 fires. Mature timber interspersed with regenerating stands following past disturbances. Low-elevation riparian corridors (Boyd Mountain, Henderson Hill, Coal Creek, Dry Creek, Tarkio, Fish Creek, Ninemile areas) serve as migration corridors and winter habitat for elk.

Elk are the primary big game species; an average of approximately 300 elk have historically wintered at lower elevations on south-facing slopes in the mid to eastern portions of the district. Cow elk wintering in HD 200 migrate to higher-elevation summer range within the district and to some extent into HD 202 (confirmed by collar studies from the late 1980s). Elk security is generally good due to the steep, heavily forested terrain. White-tailed deer are present throughout, with good populations in the river bottoms and lower slopes. Mule deer are present but populations have declined from historical levels; larger bucks are increasingly difficult to find. Black bears inhabit the heavily timbered drainages. Mountain lions are present. Gray wolves have recolonized the Clark Fork corridor. The Clark Fork River and its tributaries support strong trout populations (cutthroat, bull trout, rainbow). Bald eagles are documented along the Clark Fork.
