Evaluating The Effectiveness Of Restoration Treatments To Enhance Oregon White Oak Systems Within The Klickitat River Watershed, Kara Caselas
Environmental Science and Management Professional Master's Project Reports
Oregon white oak (Quercus garryanna) and associated plant communities provide key habitat to a number of plant and animal species, including Washington state listed threatened populations of Western grey squirrel. Over the past 150 years, human actions such as logging, fire suppression and grazing have altered stand structure and species composition of oak systems, reducing the extent and quality of historic Oregon white oak habitat. Oregon white oak and associated habitats are common in Klickitat County, which has one of the largest remaining acreages of Oregon white oak systems in the state of Washington. While most oak systems …
Effects Of Variable Density Thinning On Spatial Patterns Of Overstory Trees In Mt. Hood National Forest, Emma Huston
Effects Of Variable Density Thinning On Spatial Patterns Of Overstory Trees In Mt. Hood National Forest, Emma Huston
Environmental Science and Management Professional Master's Project Reports
Variable density thinning (VDT) is a method of restoration thinning that attempts to increase ecosystem resilience and spatial heterogeneity in forest stands to more closely resemble mosaic-like patterns characteristic of late-successional forests, which consist of clusters of multiple trees, individual trees, and gaps. This study examines the spatial patterning of overstory trees resulting from VDT of conifer forests in Mt. Hood National Forest in the western Cascade Mountains and compares these patterns with reference conditions. Stem maps were created from field surveys of study plots within one mature stand and six thinned stands designated as Late-Successional Reserve (LSR) with varying …
