Population Dynamics Early hunting records are sparse; however it is thought that high harvest in the early 1900s contributed to the decline of sage grouse. Department records indicate that the sage grouse season reopened in 1955 where 59 birds were harvested. Thereafter, the season was open and closed with little information available in respect to harvest. The season was again closed from 1980-1999, and re-opened in 2000. Since then, an average of 36 hunters per year take the field with an average of 18 sage grouse harvested annually. Hunters are interviewed in the field and biological data is ascertained to determine age and sex information, providing some insight to reproduction; although acquired from a limited sample size. Current Status Sage grouse are monitored by spring lek counts. Observers count the total number of males on each lek and this information is used as a reference point to compare current numbers to the previous year and historical numbers. In the spring of 2007, a total of 31 leks were surveyed, 24 were considered active and had displaying males, with a total of 560 males counted. Through data collected by spring lek counts and current research projects conducted by South Dakota State University, the estimated breeding population of sage grouse in the spring of 2007 was 1,500.
