Applegate, Oregon

The unit spans roughly 1,324 square miles with elevations from about 1,200 feet in the valley lowlands to approximately 7,532 feet at Mount Ashland near the eastern unit boundary. Lowland terrain between 1,200 and 1,700 feet consists of broad flat valleys, including the Illinois Valley and the Applegate River corridor; foothills rise to about 2,500 feet; and the higher Siskiyou Mountains ridgelines sit at 4,000–5,000 feet with isolated peaks above 7,000 feet. The Red Buttes in the southern wilderness area reach 6,739 feet at the eastern summit. Much of the unit is steep and rugged.

Primary highway access is via Interstate 5 along the eastern boundary through Grants Pass, US Highway 199 (Redwood Highway) along the western edge through Cave Junction and the Illinois Valley, and Oregon Highway 238 southwest from Medford through Ruch into the Applegate Valley. Upper Applegate Road (Forest Road 10) runs south from Ruch past the Star Ranger Station to Applegate Lake and into the southern National Forest interior. The Rogue River-Siskiyou National Forest (Siskiyou Mountains Ranger District, 6941 Upper Applegate Road, Jacksonville, OR 97530; 541-899-3800) administers the majority of public forest land in the southern two-thirds of the unit. The Medford BLM district covers portions of the northern unit mixed with private land. Much of the National Forest is accessible via an extensive system of paved and gravel forest roads; four-wheel-drive or high-clearance vehicles are recommended for backcountry forest roads. The Red Buttes Wilderness (straddling the Siskiyou crest on the Oregon-California border) is accessible from trailheads including Boundary, Fir Glade, Cameron Meadows, Shoofly, Steve's Fork, Sucker Creek-Illinois Valley, and Tannen Lakes; motorized equipment is prohibited in the Wilderness. Motor Vehicle Use Maps (MVUM) for the Siskiyou Mountains Ranger District designate which roads are open to public motorized travel; hunters should consult the MVUM before off-road vehicle use. The northern portion of the unit has significant private timberland and agricultural land intermixed with BLM parcels; access to these areas requires landowner permission or confirmation of BLM parcel locations.

Lower elevations and north-facing slopes support dense coniferous forest dominated by Douglas-fir, with alder, ash, and bigleaf maple along stream bottoms. Foothills and mid-elevation slopes carry a mixed-conifer matrix of Douglas-fir, ponderosa pine, sugar pine, and incense cedar, interspersed with large clearcuts and grassy openings that provide browse and forage. Higher ridges and peaks support spruce, cedar, and subalpine fir. The unit is botanically diverse due to the Siskiyou floristic region; brushy patches with oaks and forbs create transitional habitat between dense forest and meadows. The southern high country around Red Buttes Wilderness includes subalpine meadows and rocky terrain.

Columbian Black-tailed deer are the primary big game species and the unit is recognized for producing mature bucks. Roosevelt elk are present throughout the unit but bulls are typically scattered and difficult to locate; elk tend to use meadows surrounded by timber on ridges and steep slopes. American black bear are common throughout the forested portions of the unit; the southwest Oregon region produces the highest bear harvest in the state. Cougar are present year-round across the unit. Wild turkey are present in parts of the unit. The Applegate River and its tributaries support salmon and steelhead runs that influence riparian wildlife dynamics. The Siskiyou Mountains' exceptional botanical diversity supports a variety of non-game wildlife including gray squirrel and numerous raptor species.
