This report analyzes and summarizes a 1988 inventory of western juniper (Juniperus occidentalis Hook.) in eastern Oregon. This inventory, conducted by the Pacific Northwest Research Station of the USDA Forest Service, was intensified to meet increased need for more information about the juniper resource than was available in previous inventories. A primary sample, using aerial photos, recorded crown cover and ownership on all juniper forest and savanna lands in eastern Oregon. The inventory sampled all private and public lands in eastern Oregon, except some lands classified as reserved and...

Drying tests and trials for western juniper (Juniperus occidentalis Hook.) were conducted between 1993 and 1996 to (1) test and refine existing dry kiln schedules; (2) develop moisture meter correction factors; (3) test dry western juniper in different types of kilns, both by itself and with ponderosa pine (Pinus ponderosa Dougl. ex Laws.); (4) explore alternative drying techniques to minimize splitting and warping caused by inherent growth stresses; and (5) test a "saw-dry-rip" program currently used in the hardwood industry to reduce splitting and cracking. Test results over a 3-year...

There are many parallels between the 1978 legislation to expand Redwood National Park and the Northwest Forest Plan, which together with the Northwest Economic Adjustment Initiative formed the 1993 Pacific Northwest Initiative. In both situations, the Federal Government sought to promote retraining for displaced workers, to undertake watershed assessment and restoration work, and to assist communities with economic planning, grants, and transitions. Both of these efforts point out the inherent conflicts between the economic and ecological objectives of watershed restoration. No one wants...

Periodic annual increments (PAI) for survivor diameters decreased curvilinearly with increasing stand density. Gross volume and basal areas PAIs increased linearly with increasing stand density. Growth of basal area and volume for the 20 largest trees per acre were reduced curvilinearly with increasing stand density. Bark beetles were the primary cause of mortality. No mortality occurred at the lowest density.

An assessment of the vegetation resources of southwest Alaska was made by using an inventory design developed by the Pacific Northwest Research Station. Satellite imagery (LANDSAT MSS), high-altitude aerial photography, and ground sampling were the major components of the design. Estimates of area for all land cover classes in the southwest region were produced. Additionally, more intensive sampling provided data for estimation of timber resources in the forest land component. Field data collection was conducted from 1991 to 1994, and data compilation progressed through 1995.

There are 234 fungal species listed in the record of decision (ROD) for amendments to Forest Service and Bureau of Land Management planning documents within the range of the northern spotted owl. There are four strategies to established guidelines for the survey and management of various organisms, including amphibians, mammals, bryophytes, mollusks, vascular plants, lichens, arthropods, and fungi. Strategy 1 (S1) entailed compiling all known distribution and ecological information on 147 fungus species. Other strategies convey protection or encourage the collecting of additional geographic...

Declines in timber harvests on public lands and new market opportunities have rekindled an interest in nontimber forest products. Such products as edible mushrooms, medicinal plants, and floral and holiday greens provide alternative sources of revenue and employment for rural communities. This paper describes and analyzes the contribution of the nontimber forest product industries in the Pacific Northwest from economic, social, and ecological perspectives. We conclude that promises of replacement for declining timber harvests has been largely unfulfilled: the nontimber forest product...

Stream temperatures were measured during summer months, 1978 to 1984, at 12 forested watersheds near John Day, Oregon, to determine temperature characteristics and assess effects of three range management strategies of increasing intensity. Maximum temperatures in streams of the 12 watersheds ranged from 12.5 to 27.8 oC. Maximum stream temperatures on four watersheds exceeded 24 oC, the recommended short-term maximum for rainbow trout (Oncorhynchus mykiss) and chinook salmon (O. tshawytscha ). Streams with greater than 75 percent stream shade maintained acceptable stream temperatures for...

This paper describes the process used to conduct the 16 risk assessment panels and a subsistence working group held during revision of the Tongass land management plan. It provides an overview of how results from the panels were used by forest managers in plan-related decisionmaking, discusses some reactions to the effort, and identifies some opportunities to improve the process. The panel results provided estimates of the relative risk that implementation of a range of alternative approaches to management of the Tongass National Forest would pose to the continued persistence across the...

Method is described for assessing the competing demands for forest resources in a forest management plan by addressing economics values, economic impacts, and perceptions of fairness around each demand. Economics trends and forces that shape the dynamic ecosystem-economy relation are developed. The method is demonstrated through an illustrative analysis of a forest-management decision in the southern Appalachian Mountains.
