grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases, version 1.2.0

Greater sage-grouse (Centrocercus urophasianus; hereafter referred to as sage-grouse) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the West (Hanser & Knick, 2011; Rowland et al., 2006). They occupy the sagebrush biome in western North America, extending east of the Sierra Nevada/Cascade Mountain ranges to the western regions of the Great Plains of the United States (Figure 1). Sage-grouse are one of the most closely monitored wildlife in North America, which has resulted in one of the most extensive monitoring databases known. However, collectively managing sage-grouse data collected by eleven states within the United States since the 1950s is very challenging, and analyses of these data present hurdles due to its large volume and breadth of methods used to record field observations. We present software that aids in the compilation of these disparate databases that can support population analyses and management of sage-grouse by states. We provide additional information and results on applying the software to sage-grouse databases in the Larger Citation section.
