Level IV: (9h) Fremont Pine/Fir Forest

Level IV: (9h) Fremont Pine/Fir Forest

The Fremont Pine/Fir Forest ecoregion contains steeply to moderately sloping mountains and high plateaus that rarely exceed timberline. Elevation varies from 5000 to 8000 feet (1524 to 2439 m).

Residual soils are common in the region, in contrast to the Pumice Plateau, where soils have been deeply buried by pumice and ash. Reservoirs, a few glacial rock-basin lakes, many springs, and high gradient intermittent and ephemeral streams occur.

The continental climate and diverse terrain support a range of vegetation types. Ponderosa pine and western juniper woodlands are common at lower elevations. White fir, sugar pine, whitebark pine, lodgepole pine, and California incense-cedar are found on north slopes and at higher elevations. Understory plants include snowberry, heartleaf arnica, Wheeler bluegrass, antelope bitterbrush, and longstolon sedge.

The region covers 1,672 square miles (4,330 km2) in Oregon, mainly on public land within the Fremont-Winema National Forest. Contiguous areas in California have not been mapped yet.
