We flew aerial line transect surveys between March 30 and May 3, 2012, to estimate the abundance of lesser prairie-chickens (Tympanuchus pallidicinctus) and lesser prairie-chicken leks in four habitat regions in the Great Plains U.S. Estimates were supplemented with data from surveys conducted by Texas Tech University in two regions in the Texas Panhandle and surveys conducted by the Oklahoma Department of Wildlife Conservation in Oklahoma. We also estimated the number of mixed species leks which contained both lesser and greater prairie-chickens (Tympanuchus cupido) and the number of hybrid lesser-greater prairie-chickens. The study area for 2012 included four regions containing the 2011 estimated occupied lesser...

Final Report,
Trends in greater sage-grouse breeding populations are typically indexed by determining the peak number of males attending a lek in a lekking season. Numerous studies have estimated negative trends in sage-grouse breeding populations over time via data collected for the last 50 years. However, the inherent bias in data collection and unknown relationship between lek counts and population size limits the utility of using counts to evaluate range-wide population trends. This study estimated trends in the male segment of greater sage-grouse breeding populations within core and periphery areas in seven habitat management zones during two time periods, 1965-2015 and 2005-2015. In addition, we compared analysis methods...
