This report documents initial findings on the response of vegetation to different intensities of slashburning on fire-sensitive sites. The study sites were 3-year-old clearcuts at mid-elevation on Vancouver Island, British Columbia. Two fire intensities plus an unburned comparison were replicated in a balanced, incomplete block design. Ocular estimates of percent cover of all ground forage were conducted prior to treatment and 1 and 2 years after burning. The unburned treatment showed increases in virtually all species over the three sampling periods. Most species that survived the burn also increased in ground coverage by the 2nd year after burning. Post-burn abundance of shrubs and conifer seedlings was significantly lower than before the burn, although mean treatment differences were significant only for red huckleberry (Vaccinium Darvifolium). Both burn intensities, however, eliminated all amabilis fir and western hemlock seedlings. Post-burn shrub cover values were consistently higher on a light impact b
