Accurate land cover maps are critical to our understanding of how water moves across the landscape and necessary to predict impacts of climate change on water resources. Wilfrid Laurier University researchers created and tested a new method to map land cover types – such as forests, bogs and fens – in the headwaters of the Scotty Creek basin, located in the southern Taiga Plains ecozone approximately 55 kilometres south of Fort Simpson, Northwest Territories (NWT).
