Sagebrush Sparrows are found in shrub-steppe habitat, particularly big sagebrush communities. They require high shrub cover and low grass and litter cover in relatively large patches.
Limiting factors
Loss of sagebrush to high-intensity, high-frequency wildfires because of invasive grasses has adversely affected Sagebrush Sparrows. They avoid densely-growing, annual invasive plants, such as cheatgrass. Sagebrush Sparrows are also sensitive to habitat fragmentation and grazing practices.
Data gaps
Determine area requirements and conditions needed to maintain 'source populations'. Evaluate the effects of Brown-headed Cowbird (Molothrus ater) parasitism on breeding success.
Conservation actions
Maintain large patches (>400 acres) of shrub-steppe habitat, with sagebrush cover at 10-25% and height >20 inches, with <10% invasive annual grasses and open ground cover >10%.
