Abstract

As the north warms approximately four times faster than the global average, northern biomes are experiencing changes at local and landscape scales. Increasing fire frequency and severity has been observed across boreal and tundra biomes as a response to this amplified warming. Understanding past, present, and future successional trajectories of change in the boreal and forest-tundra may be useful in addressing climate change in the north. This study uses remote sensing to explore the relative effects of fire severity and forest regeneration changes post-fire across the forest-tundra and boreal regions of Canada’s Northwest Territories. Preliminary results suggest similar burn severities among fires in the Boreal and Forest-Tundra regions, and quicker recovery in the Boreal.
