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
Sharp-tailed grouse been documented by many other researchers. Goddard et al. (2009) found that sharp-tailed grouse hens in Alberta, Canada selected more for shrub steppe habitats in their first nest attempts because of increased concealment provided by the shrubs than the residual grass earlier in the breeding season. Roersma (2001) also found that grouse in southern Alberta selected taller, woody vegetation compared to all other habitats assessed, and grouse used this area in greater proportions to available woody habitat. These findings contradict Prose et al. (2002), who states that residual vegetation is critical to sharp-tailed grouse nest success due to the early
