Bumblebee community surveys used occupancy survey designs primarily across lands managed by the Bureau of Land Management (BLM) and Glacier National Park (GNP). They also include a few surveys in Nevada. These records represent timed surveys that were both successful and unsuccessful in detecting western bumblebees.

Relieving the Sting: Spatial Prioritization for Pollinator Conservation Under a Changing Climate
Project Overview The Rusty Patched Bumble Bee, and other native bees and pollinators, are declining due to climate change, habitat loss, and other stressors like pathogens and pesticide-use. Researchers supported by this Midwest CASC project will study how certain stressors interact to affect the geographic distribution of Rusty Patched Bumble Bees, using mapping techniques and future climate data to identify vulnerable populations and future strongholds. A resulting model and web application will enable resource managers and conservation practitioners to improve pollinator recovery efforts by identifying and prioritizing future locations for conservation action, including potential species reintroductions.

Bee Atlas
Bumble bee populations have decreased rapidly in the past 25 years resulting in the IUCN Red List identifying 12 species, more than 25% of all species in America north of Mexico, as species of conservation concern. The Great Plains is the mixing pot for eastern and western species, with historic records for 22 bumble bee species (nearly 50% of the North American fauna), including eight species identified as threatened by the IUCN Red List and four species currently listed as threatened, endangered, or petitioned for T&E status and at least two more that may be petitioned in the near future. The FWS relies on the best available science to make listing and conservation decisions, yet existing data sets are outdated...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
