US: Weasel-like mammal endangered in southern Sierra Nevada

FILE - In this Dec. 2, 2016 file photo, a Pacific fisher takes off running after being released into a forest at Mount Rainier National Park, Wash. The Pacific fisher, a weasel-like carnivore native to Oregon's southern old growth forests, has been denied endangered species protection in the state, the latest twist in a legal back-and-forth that has continued for 20 years. In the decision issued last week, the U.S. Fish and Wildlife Service declined to grant the fisher threatened status in southern Oregon and northern California, citing voluntary conservation measures as effective in protecting the woodland creatures. Today, biologists estimate anywhere from a few hundred to a couple thousand fishers live in Oregon, most near the California border.
