The western spruce budworm, Choristoneura occidentalis Freeman, is a native defoliator of interior Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) forests in British Columbia. Repeated budworm defo...
Inspired by collaborative work among researchers from the two jurisdictions, we explore the commercial mushroom industry in the Republic of Korea and British Columbia, Canada, searching for similariti...
This study examined birds and their association with forest structure and elevation in 1992 and 1993. The research sites were located in old-growth forest stands (251+ years) distributed between 400 a...
Water quality data from a synoptic survey of low-order streams (n = 581) were investigated as a function of the biogeoclimatic zone and moisture subzone groupings of the biogeoclimatic ecological clas...
A growing literature considers how the forest management community will have to adapt to future climate change impacts. Recently in this journal, Spittlehouse and Stewart presented a framework for pla...
Bald eagle (Haliaeetus leucocephalus) nest site and nest tree characteristics were studied in the Sub-Boreal Spruce (SBS), Interior Cedar–Hemlock (ICH), Sub-Boreal Pine–Spruce (SBPS), and interior Do...
Ectomycorrhizae are fungus-root associations that comprise the feeder roots of most commercially important conifers in British Columbia. A large body of research has been conducted on ectomycorrhizae ...
Ecosystem management is an approach to natural resource planning that theoretically places environmental issues on an equal footing with the economic concerns that dominate resource use. This approac...
Four commonly held beliefs about litter decomposition rates were tested in a suite of field experiments in British Columbia forests: (1) decomposition is slower in cold (northern and high-elevation) f...
This extension note summarizes the biology, traditional use, harvest method, and habitat of pine mushrooms in British Columbia and briefly discusses how information on habitat can be used to integrate...
Generally, studies on biodiversity conservation have focused on topics within the natural sciences, such as species and ecosystem concerns. However, an understanding of the human dimensions of biodive...
This paper outlines a method of developing indicators of well-being in small, forest-based communities. It also describes some specific measures of well-being in a particular forest-based community in...
Forest grazing occurs on replanted or naturally regenerated cutblocks, giving temporary grazing opportunities for British Columbias beef industry. However, grazing on forest cutblocks sometimes resu...
This preliminary study examined the impact of mountain pine beetle (Dendroctonus ponderosae) infestation and subsequent canopy mortality on ground snow accumulation and ablation in lodgepole pine (Pin...
The H60 contour elevation (i.e., elevation above which 60% of the watershed lies) is commonly used in hydrologic impact assessments of snowmelt-dominated watersheds in the interior of British Columbia...
