Knowledge of the survival of the Pileated Woodpecker (Dryocopus pileatus) is essential in managing viable populations of the species. In eight study areas in northeastern Oregon, survivorship of adult Pileated Woodpeckers was 0.60 after 6 mo, 0.47 after 12 me, and 0.35 after 18 mo. Of…

Western hemlock (Tsuga heterophylla) can be characterized by localized regions of high-moisture-content wood, often referred to as wet pockets, and uneven drying conditions may occur when lumber of higher and lower moisture content is mixed together in a dry kiln. The primary objective of…

Despite abundant forest resources in the state, the Alaska forest products industry declined throughout the 1990s and early 21st century. In a state with lots of trees, mills are going out of business and most finished lumber used in the state is imported from the lower 48 United States and Canada…

Arizona's natural ponderosa pine stands are characterized by open, mature groups and adjacent closed, dense thickets. The open structure of the mature groups permits a warm, dry environment, resulting in very low fuel moisture during much of the fire season and creating high ignition and fire…

Southwestern pinyon-juniper and juniper woodlands cover large areas of the western United States. The woodlands have been viewed as places of beauty and sources of valuable resource products or as weed-dominated landscapes that hinder the production of forage for livestock. They are special places…

Efficiency of harvest, overstory regrowth, and regeneration establishment are compared among 12 even- and uneven-aged regeneration cuttings installed in 1984 in subalpine Engelmann spruce and lodgepole pine forests on the Fraser Experimental Forest in central Colorado. Individual tree selection and…

In the early 1980s, silviculturists with the Northeastern Research Station and Monongahela National Forest envisioned that managing some Appalachian hardwood stands to promote two-age structures would be part of an effective strategy for managing multi-use forests. Two-age stands provided the light…
