1Principal Entomologist and Project Leader (retired), Forestry Sciences Laboratory, USDA Forest Service, Moscow, ID; 2Forest Entomologist, USDA Forest Service, Forest Health Protection, Northern Region, Coeur d’Alene, ID. Douglas-fir beetle galleries are distinctive, having eggs laid individually in niches alternating on opposite sides of the gallery. The Douglas-fir beetle (Dendroctonus pseudo...
متن کاملManaging the Dry Douglas-fir Forests
Uneven-aged interior Douglas-fir stand structure and dynamics are complexas a result of irregular fire history, insect and disease outbreaks, and variousforms of partial harvesting and range use. Stocking, crown closure, canopylayering, size-age relationships, and spatial distribution are highly variablefrom one stand to another and within any one stand. Many different factors<l...
متن کاملForest Restoration Using Variable Density Thinning: Lessons from Douglas-Fir Stands in Western Oregon
A large research effort was initiated in the 1990s in western United States and Canada to investigate how the development of old-growth structures can be accelerated in young even-aged stands that regenerated following clearcut harvests, while also providing income and ecosystem services. Large-scale experiments were established to compare effects of thinning arrangements (e.g., spatial variabi...
متن کاملSoil and Douglas-fir (Pseudotsuga menziesii) foliar nitrogen responses to variable logging-debris retention and competing vegetation control in the Pacific Northwest
Experimental treatments of logging-debris retention (0%, 40%, or 80% surface coverage) and competing vegetation control (initial or annual applications) were installed at two sites in the Pacific Northwest following clearcutting Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) stands to assess short-term effects on tree N acquisition, soil N supply, and total soil N. Vegetation...
متن کاملFluorescence microscopy of Douglas fir foliage epiflora.
BERNSTEIN, M. E. H. M. HOWARD. and G. C. CARROLL. 1973. Fluorescence microscopy of Douglas fir foliage epifloia. Can. J. Microbiol. 19: 1129-1130. Douglas fir needles stained with the fluorescent dye, primulin, were observed microscopically using epiillumination with a mercury arc light source. Microorganisms fell into three categories: algae, which exhibited primary fluorescence; actinomycetes...
