The Colorado Division of Wildlife (CDOW) proposes to conduct a study of the Parachute/Piceance/Roan (PPR) population of greater sage-grouse during 2007 and 2008. The PPR is one of several small, spatially fragmented populations of sage-grouse in Colorado. The CDOW is interested in working with energy companies and other land owners and managers in the PPR area to sustain the PPR grouse population and plan for future management actions. The objectives of the study are to obtain current, baseline information on the genetic characteristics; measures of reproduction and survival rates; and patterns of habitat use and seasonal movements of sage-grouse in this population.
