Abstract Ecosystem-based management (EBM) is a landscape-level and planning process that common across North America. A primary tenet of EBM the area intensity anthropogenic disturbance should mimic historical natural focal ecosystem. Biodiversity persist, at least coarse scale, where disturbance, such as forest harvesting, matches disturbance. However, failing some species, particularly those are dependent on old forest. Across many areas Canada, woodland caribou (Rangifer tarandus caribou) declining because direct indirect effects habitat loss fragmentation. This even though often follows principles EBM. We conducted qualitative comparison responses to wildfire considering broad range responses, including selection distribution, forage, movement patterns, population dynamics. found while harvesting both influence caribou, negative generally greater following harvesting. For example, result in habitat, but more likely shift, abandon or contract their response harvest. The literature also suggested stronger harvest when compared wildfire. difference could be residual structure associated with well extensive resource roads necessary for forestry operations.

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. Caribou will burns, such relationships are complicated by cumulative landscape change. It important recognise plasticity behaviour developing land-use strategies represent multi-year, seasonal requirements population.
