The Clark's Nutcracker is an uncommon resident in the mountains of southern British Columbia and Alberta. Breeding Bird Survey and Christmas Bird Count results suggest little overall change in the population since about 1970. Despite the stability in the population trend, there are concerns around serious declines in the two species of pine trees on which the nutcracker relies on for winter food (Tomback 1998). This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.

Conservation and management

The Clark's Nutcracker relies on the seeds of certain pine species for its fall and winter food; in Canada these are whitebark pine and ponderosa pine. Pine beetle epidemics have reduced the populations of both these species, and white pine blister rust is a continuing concern for whitebark pine populations (Tomback 1998). 

 

Bird Conservation Region Strategies

Environment Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified either because of conservation concerns (i.e., those species vulnerable due to population size, distribution, population trend, abundance, or threats) or because of stewardship responsibilities (i.e., those species that typify the regional avifauna or have a large proportion of their range or population in the sub-region). Select any of the sub-regions below to view the BCR strategy for that region.
