Fire and lichen dynamics in the Taiga Shield of the Northwest Territories and implications for barren‐ground caribou winter forage

Abstract: Questions:Fire is the main disturbance agent in boreal forests and has profound effects on vegetation composition and structure, including terrestrial lichens that provide critical winter forage for barren-ground caribou. What is the influence of fire on forest structure and the distribution and species assemblage of forage lichens? What is the current or potential effect of climate change on forage lichen in the boreal forest?Location: High Boreal, Low Subarctic, and High Subarctic ecoregions of the Taiga Shi… Show more

“…Biomass thresholds that fail to account for different timelines to recovery will neglect important regional variability. Forest structure and composition as well as soil moisture regime are important drivers of lichen cover (Lewis et al 2019). Our results suggest that drainage can influence lichen biomass accumulation in spruce-dominated stands.…”

“…Fire is a prominent landscape process in both of the Taiga ecozones and plays a dominant role in governing forest structure and composition. Describing a fire regime for the region is challenging as fire size and frequency vary considerably and fire events are often of mixed-severity (Lewis et al 2019). Nonetheless, over 50% of the treed area contained within the range of the Bathurst herd has burned at least once since fire mapping began in 1965 (Table 1).…”

“…Declines in available forage may also be associated with the changes we observed on the winter range. Lichens comprise between 50-75% of barren-ground caribou diet in winter (Lewis et al 2019). Yet recovery of lichen after fire can lag significantly behind other vegetation.…”
