grsg_lekdb: Compiling and standardizing greater sage-grouse lek databases (ver. 1.4.0)

Greater sage-grouse (Centrocercus urophasianus) are landscape-scale sagebrush obligate species and an important gamebird and iconic species of the western United States. 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. 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, sage-grouse data are collected by eleven states within the United States since the 1950s, and analyses of these data present hurdles due to its large volume and breadth of methods (defined by each state) used to record field observations. We present software that aids in compiling these disparate databases that can support population analyses and management of sage-grouse by states. The software and results reflect the most recent sage-grouse data.
