region now in abundance. South Selkirk mountain caribou The southern end of the Selkirk Mountains was the home of the last naturally occurring caribou herd in the contiguous United States, the South Selkirk mountain caribou. The herd was cross boundary, spending some time in extreme northern Idaho, eastern Washington, and British Columbia, Canada. The South Selkirk mountain caribou is a woodland mountain caribou, an ecotype of the boreal woodland caribou, one of the most critically endangered mammals. In 2009 the herd of 50 animals was declining, by April 2018, only three remained, and in January 2019, the American Association for the Advancement of Science (AAAS) announced in its scientific journal, Science, that British Columbia's provincial biologists captured the female caribou in Canada and moved her to a captive rearing pen near Revelstoke in the hopes of "preserving highly endangered herds". According to the AAAS, it is believed that this female caribou is the "last member of the last herd to regularly cross into the lower 48 states from Canada".
