FWS R1 OFWO Franklin's bumble bee High Priority Zones

The High Priority Zones (HPZs) polygons for Franklin's bumble bee are a subset of geographic areas within the historic range of the species. The HPZs are areas where Franklin's bumble bee are more likely to occur, and within which actions (such as habitat management) and events (such as wildfire) are more likely to have affects on the species. The HPZs have been modelled based off of known historic Franklin's bumble bee occurrences, along with a reclassified National Land Cover Database (2019) layer. The High Priority Zones (HPZs) is fundamentally based on a cost distance analysis using historic Franklin's bumble bee observations as source points and a reclassified National Land Cover Database (2019) layer as the barrier surface. This method follows closely with that used for the rusty patched bumble bee.
