DWB Forestry Services Ltd. Was retained by Canadian Forest Products Ltd -Vanderhoof Division to implement and assess proposed management strategies for riparian indicator species, and species indicators. Six sites were established in four different retention levels (harvested, partial, 10-meter reserve, and unharvested) along small wetlands within the Vanderhoof Defined Forest Area. We found that of the proposed indicator species (mink, longtailed weasel, beaver, moose, and eastern kingbird and guilds), moose and long-tailed weasel were the most abundant and suitable species for analysis. At the sample sites, habitat was poorly suited for mink and beaver due to a lack large of streams or waterbodies, resulting in no detections of these species. Among the 4 retention levels, no statistically significant difference was found for any of the proposed indicator species. Overall bird detection and overall mammal detection was greatest in partial retention areas. Shrub abundance and rooting depth was found to be the most suitable species indicator measurement, and was strongly positively correlated to overall bird, and combined overall bird and mammal abundance. The only species indicators that showed significant differences between retention type were minimum diameter, maximum diameter, rooting depth, woody debris volume, and forest edge length.
