Abstract
With permafrost distribution controlled largely by topography and climate, this study examines the influence of climate and permafrost conditions on standing tree biomass along a climatic gradient extending from the Mid-Boreal Ecoclimatic Region in the southern Northwest Territories to the High Subarctic environments near the arctic tree line at Inuvik. At each of 25 sites, plots were established in areas of permafrost-affected peatlands (peat plateaux), areas of permafrost thaw (collapse scars), and adjacent forest environments occurring on mineral soils (upland forests). Significant (alpha=0.05) changes in tree biomass were observed along both the climatic and topographic gradients examined with results demonstrating the complexities of permafrost environments.
