Worldwide Species Action Plans

White-tailed Ptarmigan action planThe greatest threat to the long-term survival of ptarmigan populations in Region 2 is global climate change, which may lead to a gradual loss of alpine habitats as the treeline moves upward in response to large-scale atmospheric temperature changes. More immediate and localized threats include grazing, mining, water development, and recreation. While alpine ecosystems are hardy and resilient to natural environmental factors, they are particularly vulnerable to human-related disturbances and may require decades, if not centuries, to recover from such disturbances. Although substantial progress has been achieved in developing techniques to restore damaged alpine landscapes, this technology is still not capable of restoring alpine plant communities to their pre-disturbance condition. The single most important feature of habitats used by ptarmigan in Region 2 is the presence of willow (Salix spp.), which is their primary food source from late fall through spring. Any activity that reduces the distribution and abundance of willow will likely have negative consequences to ptarmigan. The primary information needed for effective conservation of white-tailed ptarmigan in Region 2 is a clearer understanding of how the species responds to alterations in habitat and changes in environmental conditions. The natural processes that perpetuate alpine ecosystems are still intact. Consequently, human intervention is not necessary other than to insure that these natural processes are not disrupted.
