Abstract

The main goal of this project was to assess provincial scale patterns and connectivity of mountain pine beetle (MPB)-susceptible stands across Alberta and Saskatchewan using graph-based connectivity methods. The approach applies spatial graphs to assess connectivity between high susceptibility stands, as well as proximity across space to known infestations. In areas with new or no current MPB attack, especially in areas within the expanding range, there is relatively high uncertainty of how the MPB may spread, such as in central-western Alberta. We developed graph-based connectivity methods to assess the spatial pattern of high susceptibility hosts across broad regions, under historic, existing or future climates. This information is aimed to help prioritize and rank stands for treatment in areas at risk of imminent or future infestation, and to identify areas for which treatment has no benefit.
