National forests, national parks and other federally-owned forests in the Pacific Northwest and Southeast Alaska hold extraordinary amounts of carbon and therefore play an important role in defending against climate change. According to United States Forest Service data, the ten national forests in the United States that store the most carbon per forested acre are all located in western Oregon, western Washington and southeast Alaska. Moist late-successional forests west of the Cascade Range mountains are among the Earth's greatest carbon storing ecosystems.
