Prairie chicken and grouse numbers are down sharply from the numbers of 2012, a wildlife biologist who monitors those populations on the Fort Pierre National Grassland says. Wildlife biologist Ruben Mares of the U.S. Forest Service said this year’s survey on the grassland’s Cedar Creek Monitoring Unit from April 29 through May 16 showed that the number of male prairie grouse sighted had declined significantly from the 2012 survey. Greater prairie chicken (Tympanuchus cupido) were down 37 percent, from 393 males in 2012 to 246 in 2013. Sharp-tailed grouse (Tympanuchus phasianellus, previously Tetrao phasianellus), were down by 57 percent, from 82 males in 2012 to 35 in 2013.
