Several small mammals were identified as useful target species to monitor herbicide impacts in the Coastal Western Hemlock Biogeoclimatic Zone on Vancouver Island and the coastal mainland, and in the Sub-Boreal Spruce Biogeoclimatic Zone. Target biogeoclimatic subzones were also identified. Because of the variability within small mammal populations, intensive monitoring is the only objective and rigorous method to assess potential impacts from habitat alteration. A method for vegetation monitoring is also presented. Further research is required on vegetation response to herbicides, small mammal use of herbicide-treated vegetation, and furbearer response to habitat alteration and changes in small mammal populations.
