Historically, between 40-60% of the Coast Range of Oregon was comprised of
structurally diverse, old forests initiated by disturbances of various spatial scales
ranging from thousands of acres (large fires) to the size of a single tree (windthrow).
The predominant regeneration method of the past several decades, however, has been...
In the interest of meeting multiple forest management goals that include maintenance of wildlife, particularly cavity-nesting birds, uneven-aged silvicultural treatments are used increasingly in the Pacific Northwest. However, questions remain regarding the responses of cavity-nesting birds and residual green trees to different harvest intensities and patterns. To study these issues,...
Unpaved roads are a critical form of infrastructure in forested landscapes but also a potential source of fine sediment that can degrade sensitive ecosystems nearby. Improved management of aggregate road surfacing can reduce sediment generation, lengthen its useful life span, reduce maintenance costs, and more importantly, mitigate the impacts of...
In the Pacific Northwest, a transition has begun that is shifting many practices in forest management. Traditionally, harvesting and regeneration has been done through clearcutting which removes all trees in the area being cut and plants an entirely new stand. Clearcutting is often the most efficient method for harvesting forests...
Strategic planning for forests subjected to multiple uses is important for management that sustains and balances these many uses. In the wildland urban interface where forests are in the backyards of members of the public who avidly recreate in them, it is also important to include the community in the...
The objectives for the use of the Oregon State
University college forest include providing both facilities
for research and teaching, and providing funding through
timber harvest. The older age-classes of the forest are
valuable for attaining both objectives. The opportunities
and costs of removing acreage in the older age classes...
This study compares the requirements of three forest certification systems, the Sustainable Forestry Institute (SFI), the Forest Stewardship Council (FSC), and the International Organization for Standardization (ISO), with the 2005 McDonald-Dunn Forest Plan Revision. The analysis was done with a series of matrices comparing the requirements of SFI and FSC...
Forest landowners are interested in practicing alternative silviculture methods on their property without having to clearcut. This publication describes a case study on the group selection method, a management style that mimics the natural gap creation that takes place in old-growth forest stands as a result of wind throw, landslides,...
The purpose of this study was to develop a plant
association classification for the mature coniferous
forests of the McDonald and Paul M. Dunn Research Forests.
A secondary objective was to quantify diversity within the
plant associations. This Forest is approximately 11,000
acres and is located 6 miles to the...
