Sage-Grouse Genetic Structure

Determining genetic variability in fragmented populations is a necessary part of endangered species conservation since the decline and extinction of populations has been linked to the loss of genetic diversity. Sage-Grouse are endangered at both the provincial and national levels in Canada. Historically, they inhabited three Canadian provinces (Alberta, Saskatchewan, and British Columbia) and 16 U.S. states, but presently occurs only in southeastern Alberta, southwestern Saskatchewan, and 11 states. The current Canadian population is estimated at approximately 450 individuals (based on 2007 lek counts) and has decreased by 66%-92% since the 1970s . Considerable habitat fragmentation occurs in both provinces and continues to be the most significant threat to Sage-Grouse. Genetic information is essential for the conservation of Sage-Grouse since it can assess the impact of the decline on the species and can provide information necessary for the recovery process.
