Abstract

As part of the International Polar Year, a series of 69 permanent monitoring plots was established in forests and permafrost-affected peatlands in the Mackenzie Valley region of Canada’s Northwest Territories. Extending from the Mid-Boreal, through the High Boreal, Low Subarctic and High Subarctic Ecoclimatic Regions, this plot network provides opportunities to examine the effects of changing climatic conditions across both current climatic and local topographic gradients. This network, which incorporates lower productivity upland forests and peatland ecosystems, is a valuable resource within the sparsely sampled northern regions of Canada and is complementary to forest management datasets typically collected in more productive upland forest environments.This report, the second in a series of three, provides a summary and details about overstory tree vegetation at the sites. The first section of the report discusses field data collection and analysis methods. The second section presents plot level summaries of the stand characteristics including species-level basal area, stem density by height class, mean, median, and biomass-weighted mean tree height, as well as estimates of stand biomass. Tree-level measurements, including breast height diameter, height, and age for representative trees cored from the surrounding stand are also included. The accompanying database provides individual tree measurements collected at each plot, along with plot-level summary data presented in the report.
