Human-eagle interactions on the lower Columbia River

Creator:: McGarigal, Kevin
Abstract:: During the past decade (1978-87), breeding success and productivity of bald eagles on the lower Columbia River (LCR) has been far below state and regional averages and well below levels required for delisting under the Endangered Species Act by the Pacific States Bald Eagle Recovery Plan. Human disturbance was suspected...

Bird-habitat relationships at multiple spatial resolutions in the Oregon Coast Range

Creator:: Brooks, Jonathan P.
Abstract:: I analyzed the relationship between avian abundance and landscape structure at five spatial resolutions for 30 subbasins in the central Oregon Coast Range using remotely sensed data and a geographic information system (GIS). I developed maps of forest successional stages from Landsat Thematic Mapper (TM) data at a spatial resolution...

Assessing alternatives for fuel reduction treatment and Pacific marten conservation in the southern Cascades and northern Sierra Nevada

Creator:: Credo, Kevin
Abstract:: Forest managers are challenged to restore resilience to forests with an elevated risk of stand-replacing fire by using mechanical thinning and prescribed fire. Implementation of these methods can be constrained by mandates to conserve sensitive wildlife species like the Pacific marten (Martes caurina). Martens avoid simplified forest stands created by...

American marten distributions over a 28 year period : relationships with landscape change in Sagehen Creek Experimental Forest, California, USA

Creator:: Moriarty, Katie M.
Abstract:: The distribution of American martens (Martes americana) within Sagehen Creek Experimental Forest (SCEF), Tahoe National Forest, California has been periodically documented from 1980–1993. This area has been the location of nine marten surveys, each involving a systematic detection/nondetection survey on the same grid. These data are an unprecedented time series...

A Multi-Spatial Scale Economic Analysis of the Impacts of Bear Damage to Douglas-fir on Private Timberlands in the Pacific Northwest

Creator:: Kline, Kristina N.
Abstract:: Black bears (Ursus americanus) in western Oregon and Washington peel bark from conifers in early spring to forage on the sugar-rich phloem and cambial tissues. This provides important energy at a time when similarly attractive forage is scarce. Bears often damage Douglas-fir (Pseudotsuga menziesii) trees in stands that are intensively...

Diel Rest Structure Selection and Multiscale Analysis of Pacific Marten Resting Habitat in Lassen National Forest, California

Creator:: Tweedy, Patrick J.
Abstract:: Forests in the western United States have changed drastically over the past 150 years given a long history of utilization (harvest and grazing) and associated fire exclusion. These actions have altered the composition and structure of these forests as well as affected ecosystem function. Current policies for federal land management...

Using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon, A 'bird's eye view' : using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon

Creator:: Halstead, Katherine E.
Abstract:: The combined effects of habitat loss, degradation, and fragmentation pose a serious threat to Earth's biodiversity, imperiling even relatively common species. 'Habitat' is necessarily a species-specific concept, and investigations of bird diversity relationships and subsequent efforts to prioritize conservation areas, are challenged by the difficulty of estimating complex habitat gradients...

Disturbance and landscape history as a reference for evaluating forest management effects at a regional scale : examples from the Coast Range of Oregon, USA

Creator:: Nonaka, Etsuko
Abstract:: History is an invaluable source of information to understand and evaluate management influences on contemporary ecosystems and landscapes. The first two chapters (Chapters 2 and 3) explored the concept of historical range of variability (HRV) in landscape structure and stand structure using a stochastic fire simulation model to simulate presettlement...

Historical disturbance regimes as a reference for forest policy

Creator:: Thompson, Jonathan R.
Abstract:: Using the historical range of forest conditions as a reference for managing landscapes has been proposed as a "coarse-filter" approach to biodiversity conservation. By emulating historical disturbance processes, it is thought that forest management can produce forest composition and structure similar to the conditions that once supported the native biota....

An ecological assessment of riparian land-use regulation, Lane County, Oregon

Creator:: Verret, Gregory Joseph
Abstract:: Riparian areas contribute to numerous ecological-maintenance functions and so are often the focus of protection efforts by land and resource management agencies. The riparian land-use regulations of one jurisdiction, Lane County, Oregon, are assessed for effectiveness in protecting ecological functions. Evaluation of the current condition of five elements of riparian...
