A key to the literature on forest growth and yield in the Pacific Northwest, 1910-1981

Creator:: Hann, David W., Riitters, K. H. (Kurt H.), and Oregon State University. Forest Research Laboratory
Abstract:: Tables are presented that summarize 108 published articles on forest growth and yield in the Pacific Northwest. Each table describes the form of the information presented, the species to which the information is applicable, the data sources used to develop the information, the data needed to predict growth and yield,...

Equations for predicting height-to-crown-base, 5-year diameter-growth rate, 5-year height-growth rate, 5-year mortality rate, and maximum size-density trajectory for Douglas-fir and western hemlock in the coastal region of the Pacific Northwest

Creator:: Hann, David W., Marshall, David D., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Using existing permanent research plot data, we developed equations for predicting height-to-crown-base (HCB), 5-yr diametergrowth rate (delta D), 5-yr height-growth rate (delta H), 5-yr mortality rate (PM), and the maximum size-density trajectory for Douglasfir and western hemlock in the coastal region of the Pacific Northwest. With the exception of the...

Habitat use by snag-associated species : a bibliography for species occurring in Oregon and Washington

Creator:: Weikel, Jennifer M., Hayes, John P. (John Parker), and Oregon State University. Forest Research Laboratory
Abstract:: Fifty-seven species of wildlife rely on or frequently use snags for breeding, roosting, or denning in Oregon and Washington. Several publications offer information on use of snags by wildlife, influence of management activities on snags and snag users, and approaches to managing snags to benefit wildlife. Because of the diverse...

Diameter growth equations for fourteen tree species in Southwest Oregon

Creator:: Hann, David W., Larsen, David R., and Oregon State University. Forest Research Laboratory
Abstract:: Equations are presented that predict individual-tree 5-year diameter growth, outside bark, for 14 tree species in southwest Oregon. The data used to develop the equations came from 19,245 trees sampled from 391 stands in the study area. These equations express diameter growth as a function of diameter at breast height,...

A key to the literature presenting tree volume and taper equations for species in the Pacific Northwest and California

Creator:: Hann, David W. and Oregon State University. Forest Research Laboratory
Abstract:: Summaries from 49 published articles on tree volume and taper equations are presented for 39 tree species found in California, Oregon, Washington, British Columbia, southeast Alaska, Idaho, and western Montana. The summaries are organized by species and then by type of equation (volume or taper). Each summary describes the types...

Mortality equations for individual trees in the mixed-conifer zone of southwest Oregon

Creator:: Hann, David W., Wang, Chao-huan, and Oregon State University. Forest Research Laboratory
Abstract:: Models of stand growth and yield must include an estimate of mortality. For individual-tree/distance-independent growth-and-yield models. it is necessary (1) to predict the probability of death of individual trees and (2) to keep stand projections within reasonable biological limits (e.g., the maximum basal area that the stand can achieve). In...

Timber harvest projections for private land in western Oregon

Creator:: Adams, Darius Mainard, 1944-, Schillinger, Randall R., Latta, Gregory S., Van Nalts, Adrienne, and Oregon State University. Forest Research Laboratory
Abstract:: In this analysis, volume-flow and market-based models of the western Oregon timber sector are developed. The volume-flow model finds the maximum, long-term, even-flow level of cut for each ownership (industry and non-industrial private forest). The market model simulates the interaction of log demand and timber owner supply to find the...

The effects of silvicultural activities on wildlife and fish populations in Oregon and the Pacific Northwest : an annotated bibliography from 1960-1999

Creator:: Maas-Hebner, Kathleen G. (Kathleen George), Schrader, Barbara A., and Oregon State University. Forest Research Laboratory
Abstract:: This annotated bibliography was compiled to provide forest managers with a comprehensive list of sources on the potential effects of silvicultural activities on wildlife and fish populations in Pacific Northwest forests. The bibliography emphasizes publications directly examining silvicultural activities and responses by these populations. Abstracts from 296 publications are indexed...

Regenerating coastal forests in Oregon : an annotated bibliography of selected ecological literature

Creator:: Loucks, Donna M., Knowe, Steven A. (Steven Alan), 1954-, Shainsky, Lauri J., Pancheco, Alex A., and Oregon State University. Forest Research Laboratory
Abstract:: This annotated bibliography was compiled to provide a comprehensive list of sources on the ecological factors that affect forest regeneration. Abstracts from 494 publications are indexed by author, species, and subject, and are arranged into 4 major sections. Topics include the effects of biotic factors, abiotic factors, and stand and...
