Stratigraphy, structure, and Early Paleozoic Gastropoda of the Callahan Area, Klamath Mountains, California

Creator:: Rohr, David Malcolm, 1947-
Abstract:: The sedimentary, metamorphic, and igneous rocks of the Callahan, California area formed on, or adjacent to, a Lower Paleozoic island arc complex which has since been tectonically disrupted. Sandstone, shale, lithic wacke, chert, banded quartzite, siliceous mudstone, conglomerate, and limestone of the eastern Klamath belt were deposited from the Middle...

Impacts of ponderosa pine forest restoration treatments on the ectomycorrhizal fungal community and fine root biomass in the Blue Mountains of Oregon

Creator:: Smith, Jane E. (Jane Elizabeth)
Abstract:: Before the arrival of Euro-Americans, the inland Pacific Northwest was settled by native people whose frequent intentional burning of the landscape promoted open stands dominated by large fire-resistant ponderosa pine. Fire suppression for nearly a century, livestock grazing, and logging of the largest trees has resulted in forests characterized by...

Thinning with prescribed fire and timber harvesting mechanization for fuels reduction and forest restoration

Creator:: Matzka, Peter J.
Abstract:: In the Blue Mountains of northeastern Oregon, prescribed fire and mechanical harvesting economics were investigated for fuels reduction and forest restoration. Using a cut-to-length harvesting system, three single-grip harvesters and three forwarders produced significantly different production rates. For the harvesters, significant variables that affected production rates were found to be:...

Ecology and distribution of riparian vegetation in the Trout Creek Mountains of southeastern Oregon

Creator:: Evenden, Angela G.
Resource Type:: Dissertation
Full Text:: representation in the seedling or smaller classes. Typical recruitment sites for many of the woody species are

Remote sensing of forest biomass dynamics using Landsat-derived disturbance and recovery history and lidar data

Creator:: Pflugmacher, Dirk
Abstract:: Improved monitoring of forest biomass is needed to quantify natural and anthropogenic effects on the terrestrial carbon cycle. Landsat's temporal and spatial coverage, fine spatial grain, and long history of earth observations provide a unique opportunity for measuring biophysical properties of vegetation across large areas and long time scales. However,...

Influences of high severity fire and postfire logging on avian and small mammal communities of the Siskiyou Mountains, Oregon, USA

Creator:: Fontaine, Joseph B.
Abstract:: High severity fire is a historical and integral disturbance process in coniferous forest types. Compounded disturbances such as multiple fires or post-disturbance management activities are increasingly common, but ecological responses are not well understood and may represent novel types of disturbances. I studied bird and small mammal communities in the...

Forest Successional and Disturbance Dynamics in the Southern Blue Mountains of Eastern Oregon

Creator:: Johnston, James D.
Abstract:: The application of modern land management practices beginning at the turn of the 20th century is widely believed to have dramatically transformed forest landscapes of the inland Pacific Northwest. Restoring historical conditions to make forests resilient to future climate and disturbance regimes is a major goal of federal forest managers....
Resource Type:: Dissertation
Full Text:: productive mixed conifer sites have generally experienced the same or greater successional change as drier

Stratigraphy and selected Ordovician brachiopods from the Horseshoe Gulch and Gregg Ranch areas, eastern Klamath Mountains, northern California

Creator:: Potter, A. W.
