Stratigraphy and genesis of soils from volcanic ash in the Blue Mountains of Eastern Oregon

Creator:: Rai, Dhanpat, 1943-
Abstract:: Investigations were conducted to (1) determine the original pattern of deposition and thickness of ash in the Ochoco and Blue Mountain areas of Oregon, (2) determine if discontinuities exist in the parent material of these soils, (3) determine the degree of mixing of ash with other materials and evaluate reworking...

Petrography of pre-Tertiary rocks of the Blue Mountains, Umatilla County, northeast Oregon

Creator:: Trauba, William Charles
Abstract:: Nine small Mesozoic plutons in TJmatilla County, northeast Oregon, crop out within an area of 58 sq km in the Blue Mountains. The plutons are divided into an earlier series of probable Permian-Triassic age and a later intrusive series of probable Late Jurassic to Middle Cretaceous age. The earlier rocks...

Effects of Douglas-fir tussock moth infestation on outdoor recreationists in the Blue Mountains, Oregon

Creator:: Delucchi, Philip B.
Abstract:: The purpose of this study was to examine the effects of the Douglas-fir tussock moth, spray control program and salvage operations have had on outdoor recreationists in the Blue Mountains in northeastern Oregon during the 1972-1974 outbreak.

Lodgepole pine development after early spacing in the Blue Mountains of Oregon

Creator:: Cochran, P.H. and Dahms, Walter G.
Abstract:: Seedlings were thinned to spacings of 5, 9, 12, 15, and 18 feet and measured periodically. Twenty-seven years after treatment, quadratic mean diameters increased curvilinearity (p < or = 0.05) as spacing increased, but total height did not differ significantly (p < or = 0.05) with spacing. Corresponding basal areas...

Growth and yield of western larch under controlled levels of stocking in the Blue Mountains of Oregon

Creator:: Cochran, P.H.
Abstract:: Repeated thinning to five growing-stock levels resulted in widely differing tree sizes and volumes per acre after 30 years. Largest trees but the least cubic-volume yield per acre were produced in the heaviest thinning level, whereas highest board-foot yields were found in intermediate thinning levels. partial defoliation by larch casebearer...

Fire Refugia Function and Composition in Dry Mixed-Conifer Forests of Oregon’s Blue Mountains

Creator:: Downing, William M.
Abstract:: Contemporary fire effects are raising concerns about the resistance and resilience of dry mixed-conifer forests to large wildfires. Fire refugia – unburned or low-severity patches within fire perimeters – are understudied components of post-fire mosaics that may be key drivers of forest recovery following high-severity fire. Little is known about...

Effects of forest management on fish habitat and macroinvertebrates in northeast Oregon streams

Creator:: Carlson, Joan Y.
Abstract:: This study describes streams in the Blue Mountains and Wallowa Mountains of Northeastern Oregon in order to characterize the interactions between the terrestrial and aquatic ecosystems and to determine how logging affects those relationships. Five stream reach pairs, each consisting of an undisturbed reach and a similar reach flowing through...
