- This annotated bibliography of published literature provides a comprehensive source of information on animal damage assessment and management for forest land managers and others in the Pacific Northwest. Citations and abstracts from more than 900 papers are indexed by subject and author. The publication complements and supplements A Silvicultural Approach to Animal Damage Management in Pacific Northwest Forests, a compendium focusing on interactions between silviculture and animal damage management. The bibliography compiles the current knowledge and experience about managing animal...AuthorsD.M. Loucks, H.C. Black, M.L. Roush, S.R. RadosevichSourceGen. Tech. Rep. PNW-GTR-262.

- A system for anchoring the guylines and skylines of cable yarding equipment is presented. A description of three types of tipping plate anchors is given. Descriptions of the installation equipment and methods specific to each type are given. Procedures for determining the correct number of anchors to install are included, as are guidelines for installing the anchors so that they will reliably withstand the forces imposed on them in this application. Charts for determining the number of anchors to install and bridle together are included. Information presented is based on field tests...AuthorsR.L. Copstead, D.D. StudierKeywordsSourceGen. Tech.

- Spotted owls (Strix occidentalis) were monitored on 11 National Forests in the Pacific Northwest Region of the USDA Forest Service between March and August of 1987. The basic intent of monitoring was to provide estimates of occupancy and reproduction rates for pairs of spotted owls. This paper documents the technical details of the statistical estimation procedures used to produce all the estimates resulting from that effort. All relevant formulae are presented as well as decisions made about collapsing strata to estimate variances. Some complicating aspects of the monitoring effort are...AuthorsTlmothy A.

- International 1/4-inch board-foot volume equations and tables were derived from fall, buck, and scale data for 374 trees at 78 locations in the Susitna River Basin, Alaska. Tree species included white and black spruce, paper birch, black cottonwood, and quaking aspen.AuthorsFrederic R. LarsonKeywordsSourceRes. Note PNW-RN-495.

- The fir decay equation for Oregon and Washington was used to predict stem decay in 12 grand fir (Abies grandis (Dougl. ex D. Don) Lindl.) stands in the Clearwater region of northern Idaho. These 12 stands represented a range in geographic and stand characteristic variation. All 12 observed decay percentages were within their associated 95-percent prediction intervals. We therefore concluded that the fir decay equation for Oregon and Washington can be used to estimate stem decay in 40- to 90-year-old grand fir stands in the Clearwater region. Information also is presented on decay biology,...AuthorsGregory M. Filip, John W. Schwandt, Susan K. HagleKeywordsSourceRes. Pap. PNW-RP-421.

- The true firs are important species in Oregon and Washington forests, but root diseases, stem decays, and dwarf mistletoes cause more mortality, growth loss, and cull in these species than in any other. This paper consolidates research, observations, and management techniques for diseases of true firs, especially the effects of silvicultural activities on root diseases, stem decays, and dwarf mistletoes.AuthorsG.M.

- Ten species and hybrids of spruce (Picea spp.) were planted and observed annually for 26 years at three coastal locations in Oregon and Washington to evaluate growth rates and susceptibility to the Sitka spruce weevil (= white pine weevil), Pissodes strobi The 10 spruce were: Sitka spruce, Norway spruce, Lutz spruce, black spruce, white spruce, Engelmann spruce, Yeddo spruce, Sakhalin spruce, an Engelmann x white spruce cross, and a Sitka x white x white backcross. Results showed Sitka and Norway spruce grew well but were badly damaged by severe weevil attack. Infestation levels peaked at...AuthorsRussel G. Mitchell, Kenneth H. Wright, Norman E.

- The adaptive environmental assessment method was used by an interdisciplinary team of forest specialists to gain an understanding of resource interactions and tradeoffs resulting from forest management activities in southeast Alaska. A forest multiresource projection model was developed in the process. The multiresource model, “SAMM,” is capable of characterizing and displaying interactions of four major resources over a 150-year rotation: timber, wildlife (Sitka black-tailed deer), hydrology (streams), and fisheries (anadromous). SAMM is in a prototype stage of development; final testing...AuthorsRoger D. Fight, Lawrence D. Garrett, Dale WeyermannKeywordsSourceGen. Tech. Rep. PNW-GTR-255.
