Slocan Forest Products Ltd. (Plateau Division) expressed a need to identify potential forest-dwelling vertebrates that could be used as monitoring indicators to support Sustainable Forest Management Plan (SFMP) initiatives throughout the Prince George Timber Supply Area. The occurrence of forest-dwelling vertebrates was identified for the Prince George Timber Supply Area (PGTSA) and the distribution, relative abundance, seasonal use and habitat affinities were identified at the biogeoclimatic subzone level (SBSmc3, SBSdk, SBSdw3, SBSmc2 and ESSFmv1) within the Vanderhoof Forest District (VFD). Based on the initial literature review, a total of 234 vertebrate species potentially occur within the Prince George TSA, of which 184 are closely associated with at least one of the six identified primary structural elements associated with forests, and therefore considered forest-dwelling. Of the 184 forest-dwelling vertebrates potentially occurring in the PGTSA, 173 potentially occur in the VFD. Of these, 11 species were excluded from the ranking as they were considered very rare and/or had no confirmed reports of breeding or wintering in the area, which reduced the list to 162 potential candidate A screening procedure was used to select forest-dwelling vertebrates according to their utility as potential monitoring indicator species. A total of 107 species were considered to have a strong association with at least one of the six identified primary structural elements and a moderate (55 species), high (39 species) or very high (13 species) sensitivity to forest management practices. Most of these species were closely associated with late seral forests (65 species), dead and dying trees (40 species) as well as riparian habitats (79 species). An intermediate number of species (16-30) are closely associated with shrubs, early seral and deciduous trees and a small number (6) of species are closely A second screening was completed to eliminate species that were considered not to be cost effective for monitoring. Within the VFD a total of 89 species (out of 107) were retained based on their sensitivity to forest practices and relative cost-effectiveness. A third screening was then completed to eliminate species that would be difficult to measure and/or provide unreliable results. Species that were eliminated in the third screening include species present in low and/or variable numbers within the VFD, bats, species with confounding factors, and species with irregular distribution and local abundance in relation to conifer cone crops. This screening resulted in a total of 54 Most of the potential candidates are birds and represent many of the species identified in the cavity-nesting community in the Cariboo-Chilcotin. The rationale for species elimination or inclusion is briefly discussed including limitations of the proposed
