Canopy epiphyte studies in the central Oregon Cascades : implications for the management of Douglas-fir forests

Creator:: Sillett, Stephen Charles
Abstract:: This thesis includes four separate studies. The first two studies assessed edge effects in a 700-year-old forest. After 20 years of exposure, epiphyte assemblages on the clearcut edge were similar to those of the forest interior, but there were some differences in vertical distribution patterns. Several species restricted to the...

Patterns of hillslope and channel recovery following disturbances in steep, forested basins

Creator:: Madej, Mary Ann
Abstract:: Geomorphic response to watershed disturbances commonly results in alterations of landforms. Subsequent geomorphic recovery is dependent on the ability of flows to entrain, transport, and organize inorganic and organic material on hillslopes and in channels. This research analyzed changes in sediment production, channel structure, and channel organization following disturbances in...

An evaluation of the economic impacts of reducing soil erosion and groundwater pollution in non-irrigated farming systems of northeastern Oregon

Creator:: Akinsanmi, Josiah Akinlayo
Abstract:: Increases in food demand, favorable commodity markets and drive towards increasing productivity at a greater economic efficiency have accelerated negative agricultural externalities, particularly erosion and water quality. The potential impact of these externalities on environmental quality and human health prompted an examination of current and potential production strategies on four...

Nutritional and managerial considerations for wintering beef cattle in the northern Great Basin

Creator:: Brandyberry, Steven D.
Abstract:: A study was conducted to determine effects of year and season on diet quality of beef cattle grazing northern Great Basin rangelands from 1990 to 1993. Forage quality was high early in the growing season, then declined as seasons progressed (P<.05). Plant chemical composition was higher early in the growing...

Spatial and temporal patterns of fire in the forests of the central Oregon Coast Range

Creator:: Impara, Peter C.
Abstract:: Fire history and fire regime were interpreted from tree ring analysis of 4320 stumps at 178 sites in a 25 by 55 km area in the central Oregon Coast Range. A total of 27 fire episodes were identified in a 516 year period, with sizes estimated at 18 to 544...
