Reports a two-year study initiated to examine the diversity of bird communities in different seral stages of the aspen ecosystem at the western end of the dry cool subzone of the sub-boreal spruce zone of the Prince Rupert Forest Region, British Columbia. Breeding birds were chosen for the study since they tend to stay within a relatively confined area once in their territories and are hence easier to count. The study also had the objective of identifying management indicator species that could represent the diversity of most birds likely to be affected by aspen management. Birds were counted by a modified point count method for clearcuts, sapling aspen stands, mature aspen stands, old aspen stands with century-old trees, and mixed aspen-conifer stands. Data were analyzed using a detrended correspondence analysis ordination procedure, and habitat relationships of the 16 most abundant species were analyzed by multiple regression.

This report examines evidence of forest fire history at the Pothole Creek Research Site near Merritt, British Columbia, as a part of a larger project investigating stand development, growth, and yield. A master chronology, constructed using samples taken from climatically sensitive trees, was used to cross-date samples collected from fire-scarred wood. The resulting pattern of past fire intervals was then employed to speculate about the historical fire regime at Pothole Creek. Results are discussed with regard to seasonality of fire, extent of fire, and fire frequency and intensity.
