Another lawsuit (PDF) has been filed to force the Fish and Wildlife Service to act on a listing petition – this time for the whitebark pine tree, which is distributed across high-elevation areas in California, Oregon, Washington, Nevada, Wyoming, Montana, and Idaho, and southwestern Canada.  The Natural Resources Defense Council petitioned (PDF) the Service to list the whitebark pine in December 2008 claiming that climate change "poses one of the most significant threats to whitebark pine." 

The whitebark pine listing petition is one of several recent petitions seeking protection under the ESA due to the threat that climate change poses to the species.  The Service recently declined to list the American pika as endangered or threatened due to climate change.  But last month the National Marine Fisheries Service determined that a petition to list 83 species of coral due to climate change presented substantial information indicating that listing might be warranted for 82 of the species.
