Title: Networking the spatial structure of boreal caribou populations in western Canada
Abstract: Delineating relevant local populations of widely distributed species is a common challenge in conservation ecology. In Canada, recovery actions for boreal caribou are stratified by local population units (LPUs), but evidence supporting their boundaries varies widely. We assembled GPS telemetry from 1,586 adult female caribou across the 19 northwesternmost LPUs, spanning northern SK, AB, NT, and northeast BC. We used a network analysis to identify candidate local populations and subpopulations. We detected local population boundaries that in some cases were consistent with accepted LPUs but in other cases were not. Several caribou “communities” at smaller spatial extents were consistent with expert and local knowledge of caribou movements and support recovery planning and actions “stepped down” from entire ranges. These results have important implications for forecasting the population resiliency of caribou.
