Abstract A questionnaire was sent to each Ranger District in the Pacific North-west Region of the USDA Forest Service to get information on present snag-management programs. Ninety-five percent of the responding Ranger Districts left snags at levels that ranged from 0.15 snags/ha (0 06/ac) to 12-15 snags/ha (5-6/ac) on all forested lands. Live trees were intentionally left as future snags on 93% of the Ranger Districts. Live trees were killed to create snags on 41% of the Ranger Districts. Management recommendations are made as to the kind of snags to leave and methods of maintaining them. West. J. Appl. For. 1:41-43, April 1986

Abstract The success of emergency wildfire rehabilitation treatments applied on USDA Forest Service land is rarely documented. Though based partially on economic efficiency criteria, treatments are often applied with little consideration of the risks involved. A decision-tree approach incorporates such risks in the rehabilitation decision process through the calculation of an expected value. This approach was applied to documented rehabilitation projects conducted on Forest Service land in the Pacific Northwest and northern Rocky Mountains from 1976 to 1981. The evaluation of past projects showed that a number of inefficient projects have been applied even without considering risk. When the risks of applying treatments are included, the efficiency of nearly all of the rehabilitation efforts becomes suspect. West. J. Appl. For. 2(2):58-61, April, 1987.

Abstract Propagation information developed at the USDA Forest Service Wind River Nursery in Carson, WA, is provided for 9 hardwood tree and 30 shrub species native to the Pacific Northwest. This includes information on: seed collection, extraction, stratification, and storage; timing of collection and propagation techniques for cuttings; and a summary of propagation experience (planting media and container used, specialized methods, and type of stock produced). Most species were propagated from seed, some from stem or root cuttings, and some from both seed and cuttings. Some species were very difficult or impossible to propagate at the nursery. West. J. Appl. For. 14(2):61-64.
