Laura Bies Posted July 3 Share Posted July 3 The U.S. Fish and Wildlife Service has listed the Mount Rainier White-tailed Ptarmigan (Lagopus leucura rainierensis) as threatened under the Endangered Species Act. According to the agency, habitat loss and degradation due to climate change will endanger the bird in the foreseeable future. The species ranges from the Cascade Mountains of Washington State from Mount Adams northward into southern British Columbia, Canada. The species was proposed for listing in 2021, and this week's final rule was aopdted after considering public comments and peer review on the species status assessment. The listing is effective August 2, 2024.

Following a rigorous review of the best available science, the Service has finalized a listing of the Mount Rainier white-tailed ptarmigan as threatened under the Endangered Species Act (ESA). The Service has determined that the loss and degradation of its habitat resulting from climate change will endanger the bird in the foreseeable future. The ESA defines a threatened species as likely to become in danger of extinction within the foreseeable future throughout all or a significant portion of its range. The Mount Rainier white-tailed ptarmigan is a unique alpine bird in the grouse family and one of the few animals that live in high-elevation environments throughout their entire life. These birds are well-adapted to life above the tree line, with feathered, snowshoe-like feet and seasonally changing plumage. Mount Rainier white-tailed ptarmigan require a mix of specific moist alpine vegetation communities, rocks and nearby snow or water. The species’ range includes the Cascade Mountains of Washington State from Mount Adams northward into southern British Columbia, Canada. Climate change is expected to significantly diminish the alpine habitat upon which the Mount Rainier white-tailed ptarmigan depends, driven chiefly by decreases in meltwater from snowpack and glaciers and a rising tree line. As the climate warms and prompts changes in vegetation, the bird’s habitat is projected to disappear. Climate change is likely to result in the loss of up to 95% of the bird’s currently available alpine tundra habitat in coming decades. “We look forward to continuing to work with federal partners and other stakeholders to conserve and recover the Mount Rainier white-tailed ptarmigan,” said Hugh Morrison, Pacific Regional Director for the Service. “Our long-standing research and conservation partnerships will provide a firm foundation for working together to recover this species, as well as others under pressure from our changing climate.” This listing comes shortly after the 50th anniversary of the ESA in 2023. It reflects the growing extinction crisis and highlights the importance of the law and efforts to conserve species before population declines become irreversible. The growing impacts of climate change further exacerbate these threats and their interactions for many species and ecosystems. The listing of Mount Rainier white-tailed ptarmigan serves as an alarm bell but also as a call to action. The Service is also finalizing a 4(d) rule that provides measures for its conservation by prohibiting take, except as otherwise authorized or permitted. Critical habitat has been found non-determinable at this time. Quote Link to comment Share on other sites More sharing options...
