The recent outbreak of mountain pine beetle (MPB) (Dendroctonus ponderosae) in British Columbia provided an opportunity to examine genetic variation of differential attack and resistance in a 20-year old lodgepole pine open-pollinated (OP) family trial. Approximately 2,500 individuals from 180 OP…

Cytochromes P450 family genes (P450s) are found in a diverse array of organisms ranging from bacteria to mammals to plants to arthropods. Although there are exceptions to this rule, organisms generally contain a fairly large number of P450 genes and pseudogenes in their genomes. For instance, among…

Major wildland/urban interface fire losses, principally residences, continue to occur. Although the problem is not new, the specific mechanisms are not well known on how structures ignite in association with wildland fires. In response to the need for a better understanding of wildland/urban…

Mountain meadows in the Pacific Northwest are patches of remarkable biological diversity. Lush, forb-, grass-, and shrub-dominated communities attract rich assemblages of arthropods, support diverse communities of birds, and provide habitat for small mammals and other wildlife. Recent encroachment…

Description, classification and delineation of visual landscape character are initial steps in developing visual resource management plans. Landscape characteristics identified as key factors in visual landscape analysis include land cover/land use and landform. Landscape types, which are…

Whitebark pine (Pinus albicaulis) is a major tree species of upper subalpine forests of the northern Rocky Mountains (Schmidt and McDonald 1990). It is an important nutritional and structural component of wildlife habitat (Arno and Hoff 1990; Schmidt and McDonald 1990). Its large, nutlike seeds are…

The Oregon Coast Range supports some of the most dense and productive forests in North America. In the pre-harvesting period these forests arose as a result of large fires-the largest covering 330,000 ha (Teensma and others 1991). These fires occurred mostly at intervals of 150 to 300 years. The…

Snags (standing dead trees) are important components of forested habitats that contribute to ecological decay and recycling processes as well as providing habitat for many life forms. As such, snags are of special interest to land managers, but information on dynamics of snag populations is lacking…

We monitored the nest densities and nest survival of seven cavity-nesting bird species, including four open-space foragers (American Kestrel [Falco sparverius], Lewis's Woodpecker [Melanerpes lewis], Western Bluebird [Sialia mexicana], and Mountain Bluebird [S. currucoides]) and three wood-foragers…
