The ecology of a population of snowshoe hares, Lepus
americanus washingtonii, was studied in western Oregon from 1960
to 1962. Objectives were to obtain information to control hares,
which frequently cause damage to coniferous reproduction in the
region, and to compare the life history of this little-studied subspecies
with others....

The ecological and silvicultural importance of snowbrush,
Ceanothus velutinus, in the areas west of the summit of the Oregon
Cascades was studied. Particular attention has been given its nitrogen-
fixing ability under both field and greenhouse conditions.
On west slopes of the Oregon Cascades snowbrush occurs above
2, 500 feet...
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...
The nonagricultural lands of the world are being called upon today to satisfy tremendous
demands from society at all levels of economic development. Until recently, costs of management
of many of these lands were too high to warrant appreciable management investment for
the relatively low yields. Society is beginning to...
Seed of Cougar and Newport Kentucky bluegrass (Poa pratensis L.)
was harvested at Pullman and Spokane at several stages of maturity.
Variations in seed attributes resulting from environmental and maturity
effects were evaluated through germination tests, tetrazolium staining,
seed moisture and seed weight determinations. Seedling vigor was
determined by .speed...
