- Abstract
Artemisia L. [Asteraceae] (sagebrush) is one of the most common shrubs in North America ([15]) and is a vital habitat component for many at-risk grassland species including the Greater Sage Grouse (Centrocercus urophasianus; hereafter sage grouse). As new methods of estimating sagebrush cover are developed, understanding the limitations and advantages of each method will be essential for agencies and individuals who use these techniques to manage and restore sagebrush habitat. We found that crown diameter could be used to determine sagebrush crown area with a high degree of confidence (r SP 2 sp = 0.96), and we were able to model sagebrush landscape cover as a function of density using sagebrush individual crown area estimates. In this research note, we revisit the data collected by [21] to quantify discrepancies in sagebrush cover estimates determined by line-intercept and crown area measurements and discuss implications for sagebrush habitat management and restoration.
