Abstract: In the interior of British Columbia forest harvesting is taking place in the 16.3 million hectares of lodgepole pine forest affected by the mountain pine beetle (Dendroctonus ponderosa) (MFML, 2008). In this paper I looked into the types and amount of work with associated hazards that are occurring in these stands. Hazards include whole and partial tree failure both of which can occur in any phase of the harvesting process. I then looked at how applicable the current wildlife/danger tree assessment method in stands comprised mainly of dead lodgepole pine. The assessment method was found to not be practical for use in these stands in its traditional form. I also looked at how hazards in these stands change over time. I found that checking and drying in the wood may be an important factor in partial tree failure. From my findings I came up with a few recommendations for forest companies with employees working in dead pine stands. One is a switch to a stand level risk assessment rather than single tree risk assessment for dead pine stands. Second the creation of a wind cut-off speed specific to stands of dead pine.
