Fig. A2. Typical boreal forest habitats in our Yukon Flats study area from before and after the wildfire. (A) Burned boreal forest up to the edge of our study lake, with little standing vegetation remaining and peat forest floor removed. (B) Exposed mineral soils near our study lake, resulting from the fire’s consumption of the organic soil and peat forest floor. (C) Fire burning in the distance, 3–4 weeks before reaching the study area. Note the dense boreal forest that surrounded the study lakes prior to the fire. (D) Typical unburned boreal forest habitat in our study area. Note the stunted black spruce and peat deposits on the forest floor, both of which are common in permafrost areas.
