Grouse Mountain mild as the Lower Mainland. In December (the coldest month statistically), Grouse Mountain has an average high and low of and respectively. This freeze/thaw cycle can allow for large amounts of rain to fall on some occasions every winter. Nonetheless, heavy snow is more frequent in the winter, which allows for a deep snow-pack, lasting on average from mid-November until early May. Summer is warm and relatively dry. August is the warmest month, with an average high and low of and respectively. Grouse Mountain has built an observation deck (accessible by elevator) on a 1.5 megawatt wind turbine of Leitwind
Greater sage-grouse 20–50%. In another Montana study, sagebrush cover averaged 30% on a cock-use area, and no cocks were observed in areas of less than 10% canopy cover. Some females probably travel between leks. In Mono County, California, the home range of marked females during one month of the breeding season was , enough area to include several active leks. DNA from feathers dropped at leks showed that about 1% of grouse may travel long distances to explore breeding areas up to 120 miles away, a type of long-distance dispersal that can potentially boost populations and temper inbreeding.
