The sagebrush bees project is investigating the response of wild bee communities to the spread of invasive annual grasses in sagebrush-steppe ecosystems. Based in eastern Oregon's Steens Mountain, the objectives of this project will provide supporting information of how pollinator communities are shifting as the wildfire-invasive grass cycle grows across much of the western US. In quantifying the bee communities across Steens Mountain and across the invasive grass gradient, sampling must include lethal take in order to record presence at a species-level scale.
