Project the future probability of occupancy of WBB in the continental U.S. based on changing temperature and precipitation for 2055 and 2085, across scenarios representing levels of the other most important stressors to Western bumblebees (e.g., status quo pesticide use, reduced pesticide use; status quo habitat, reduced habitat based on future development projections). Based on occupancy predictions and a bootstrap approach, enumerate the number and location of populations (defined based on grid cells as in prior bumble bee SSAs) across the distribution in the continental U.S. under the above scenarios. Identify areas where management of stressors are most likely to lead to conservation of populations versus local extirpation.
