This project was developed to identify a set of risk indicators to predict the risk of summer-ground loss at the watershed level within the Vanderhoof Forest District (VFD) and others, subsequent to the mountain pine beetle (MPB) infestation of lodgepole pine stands. This report was done in relation to the VFD annual cut of stands, and the following difficultings that operators found in running their equipment in wet versus dry soils in harvest years. Risk indicators were selected from available GIS information, aerial photographs, and local knowledge. The most effective indicators for predicting the risk of wet-ground areas at the watershed level were found to be lodgepole pine content, understorey, drainage density, sensitive soils, and the topographic index, all of whose values are available from provincial databases. The work includes information on materials and methods, results and discussion, the authors' conclusions, as well as recommendations.--Includes text from document.

This publication supplements Wood & Bright's 1992 catalogue of the world's Scolytidae and Platypodidae (bark beetles), updating the taxonomy of these two families to nearly the end of 1995 and including all known literature references to the end of 1994 (plus references to articles missed in the earlier bibliography). References which provide new information on taxonomy, host plants, or biology of a species are also included. The format of the supplement closely follows that of the 1992 catalogue. Each genus & species is listed with its page number from that catalogue; additional information on figures, distribution, hosts, and references to other subject areas are given. The publication also includes lists of host plants, arranged by scientific name, and the beetles attacking them.

This paper presents the results of a project done to assess the potential for impacts and changes to the peak-flow regime throughout various sub-basins of the Fraser River Watershed. The vast size and the physical complexity of the Fraser River Basin make it extremely difficult to directly measure the hydrologic effects of beetle kill and salvage harvesting. As a result, a hydrology model has been used to assess the hydrologic consequences of the current outbreak. The project is part of a larger effort in quantifying the water resource impacts of the pine beetle and salvage harvesting across a range of watershed scales.--Includes text from document.

The current synthesis is a review of research examining the effects of large-scale mountain pine beetle (MPB)-related disturbance conducted predominantly over the past five years. The emphasis is on research that explicitly examines the impact of beetle kill (or biotic disturbance in general) and the cumulative effects of large scale salvage harvesting operations in response to beetle kill. In general, forest disturbance has been found to increase snow accumulation and melt, reduce interception loss and evaporation, and increase runoff and stream flow.--Document.
