The study described in this report is part of a larger project intended to address concerns about the effects of clear-cut harvesting on high-elevation forests in southern interior British Columbia. The study investigated microclimatic conditions in mature forest and in clear-cuts of 0.1 to 10 hectares. Parameters measured include solar radiation, ultraviolet-B radiation, energy balance (fluxes of net radiation, soil heat, sensible heat, & water vapour), wind speed, precipitation & snow melt, and air & soil temperature. Results compare measurements made in forests with those made in the openings. Implications of the findings for plants & for forest hydrology are discussed.

Microclimate has a significant influence on the survival and growth of seedlings. Presents examples of how site preparation can modify microclimate.
