Summary of Methods: Aldridge and Brigham looked at the change in sage grouse population numbers in central Canada over the past 50-60 years. They mentioned a number of limiting factors that are having an affect on reducing bird numbers mainly through habitat alteration, and looked at agriculture practices and overgrazing as the two main problems. Grazing reduces the vegetation cover, which can expose the birds to predators or to severe weather as well as decreasing forage for the birds themselves. The authors urged for cooperative management within the area to try and keep in tact the little sage grouse habitat that still exists.
