During winter, woodland caribou ( Rangifer tarandus caribou) may avoid burned forest for up to 60 years. Typically, that is the time required lichens recover following fire. We examined response of Klaza population (west-central Yukon, Canada) recent burns (≤50 years) during winter. quantified resource selection individual across winter range and use habitats were adjacent or within burns. selected used areas with greater density terrestrial lichen. There was considerable inter-animal variability, but in some season-years habitat stronger relatively small Approximately 6.2% GPS-collar locations located outside 500 m boundary a burn 5.6% occurred burn. late when snow deeper, demonstrated avoidance Our results suggest relationship between dynamic.
