Distribution of understory species in relation to maximum and minimum tree influence in the montane forest of the Central Oregon Cascades

Creator:: Robinson, Andrew Frederick, Jr.
Abstract:: Twenty sites of uniform topography and soil were select ed in the montane forest found on the East flank of the Central Oregon Cascades. These sites were located along a vegetational gradient composed of five plant communities: Abies/Pachistima, Pinus/Ceanothus, Pinus Arctostaphylos-Purshia, Pinus/Purshia/Festuca, and Juniperus Festuca. An attempt was made to...

Ground dwelling beetles in early and late successional forests in the western Cascades of Oregon

Creator:: Heyborne, William H.
Abstract:: The effects of forest cutting on forested systems and the biotic components of those systems has been at the forefront of scientific research. The inventory and monitoring of biodiversity is one technique used for measuring the effects of forest management. Because bioinventory studies are expensive, indicator species are often sought...

Structural and functional comparison of human-impacted and natural forest landscapes in the western Cascades of Oregon

Creator:: Pennington, Deana D.
Abstract:: This study compared effects of human and natural wildfire disturbance on age class distribution and associated ecosystem properties of forests in a 15,670 km2 area of the western Cascades of Oregon. The study site is characterized by three forest use types: low elevation, intensively harvested private industrial lands; mid elevation...

Mixed-conifer forests of central Oregon : structure, composition, history of establishment, and growth

Creator:: Merschel, Andrew G.
Abstract:: The structure and composition of mixed-conifer forest (MCF) in central Oregon has been altered by fire exclusion and logging. The resulting increased density, spatial contagion, and loss of fire resistant trees decrease the resiliency of this ecosystem to fire, drought, and insects. The historical and current composition and structure of...

Nutrient losses and nitrogen mineralization on forested watersheds in Oregon's Coast Range

Creator:: Miller, James H.
Abstract:: Nutrient losses of the biologically responsive anions, nitrate and bicarbonate together with the major cations, were monitored on 14 small watersheds in Oregon's Coast Range and evaluated in relation to management-induced disturbance. Mixed forests of Douglas-fir and red alder had dominated these high-nitrogen sites prior to treatment. A paired-watershed experimental...

Empirical modeling of windthrow occurrence in streamside buffer strips

Creator:: Drake, Timothy P.
Abstract:: Streamside buffer strips provide numerous benefits to stream ecosystems. The buffer strips create shade, provide shelter for wildlife, act as barriers to logging debris during and after timber harvest, and serve as a continued source of large woody debris. Quantifying woody inputs resulting from windthrow provides managers with estimates for...

Remote sensing of forest aboveground biomass using the Geoscience Laser Altimeter System

Creator:: Pflugmacher, Dirk
Abstract:: Accurate estimates of forest aboveground biomass are needed to reduce uncertainties in the terrestrial carbon flux. The Geoscience Laser Altimeter System (GLAS) onboard the Ice, Cloud and land Elevation Satellite is now the first spaceborne lidar sensor that will provide global estimates of vegetation height. This study investigated the utility...

Tradeoffs associated with managing forested landscapes for multiple-uses

Creator:: Lichtenstein, Mark E.
Abstract:: This study focuses on the tradeoffs that exist for managing forested landscapes for biodiversity and timber production. Tradeoff evaluation is important to natural resource managers so they can understand the benefits and costs of alternative management prescriptions. The study examines three watersheds in the Oregon Coast Range and 166 terrestrial...
