The objective of this cooperative research is to determine the diversity of wild bees in the Western U.S. and evaluate factors important to their preservation.
Wild bees will be studied in the Western U.S., especially the Great Basin and adjoining regions, sampling in and out of past wildfires on wildflower species targeted for use in restoration seeding projects. All bees will be identified for calculating their abundance and diversity. Geographical information systems will be used to evaluate bee populations as they are distributed in time and space. For bumble bees, historical records and DNA analysis will be used to evaluate whether populations are expanding or contracting in range, and whether any species are under threat of extinction. Their mortality factors, such as diseases and parasites, will also be evaluated.
