This map was produced as part of a biophysical mapping pilot study carried out in the Watson Lake (NTS 105A/2) area in 2004. Biophysical mapping (also known as ecological land classification) is an integral system of mapping describing terrain conditions (surficial geology, slope, landscape position, drainage and permafrost conditions), as well as ecological values (vegetation community and structure, and soil moisture and nutrient regimes). At a local level (1:50 000) scale, biophysical maps are an essential tool for facilitating stewrdship and sustainable development of energy, mineral and land resources.
