Abstract

The Columbian sharp-tailed grouse was once the most abundant game bird in the Inland Northwest area. The main reason for their loss was the conversion of their habitat into agricultural lands and timber forests. Several variables were incorporated into a weighted sum tool in ArcGIS using public raster layers for each of three seasons. The results layers were analyzed using the same tool to find the most suitable habitat. Six locations in the county had 50% or better suitability. One location showed 80% or better. The grouse historic range appears to coincide with Palouse prairielands in Benewah County. Further research should be conducted to fine tune the weights of the variables and more refined data layers would yield better results.
