Prairie chickens use the same leks each year.
Another term for leks is "booming grounds." The male emits a "booming" sound while strutting around his territory. On a calm day, this characteristic booming may be heard a mile away.
Since 1900, the total number of lesser prairie-chickens has decreased by an estimated 97 percent. Conversion of habitat to cropland was the primary culprit, though market hunting, brush control and overgrazing were contributing factors. Attempts to establish new populations have failed.
The CMP was created by the U.S. Congress. The original purpose was to provide civilians an opportunity to learn and practice marksmanship skills so they would be skilled marksmen if later called on to serve the U.S. military.
The Civilian Marksmanship Program (CMP) promotes firearms safety training and rifle practice for all qualified U.S. citizens with special emphasis on youth.
The CMP is authorized to provide support and encouragement to clubs and state associations with emphasis on strong junior programs.
