The study was conducted on the Ochoco National Forest in
central Oregon. Vegetation-soil relationships were evaluated for the
following objectives: 1. Develop a sound ecological foundation on
which total land management decisions may be based. 2. Evaluate
forest succession, stocking, and growth to improve management.
3. Develop accurate range condition...
Growth basal area (GBA) is that basal area at which dominant trees grow at 1.0 inch in diameter per decade at age 100. Diameter growth rate of 1.0 inch per decade is a constant used to compare sites; basal area is a variable used to express stockability. GBA is a...
Secondary plant succession and the accumulation of biomass and nutrients were
documented at seven ruminant exclosures in Abies and Pseudotsuga forests variously
disturbed by logging, burning, and grass seeding. Long-term (25 or more
years) foraging by Rocky Mountain mule deer (Odocolleus hemionus) and Rocky
Mountain elk (Genius elaphus) suppressed the...
