Restoration of river otters into the Colorado River ecosystem in Grand Canyon: A Synopsis of background information and issues
Grand Canyon Wildlands Council, Inc.. 2004. Restoration of river otters into the Colorado River ecosystem in Grand Canyon: A Synopsis of background information and issues. Flagstaff, Ariz.
Large vertebrate predators shape their ecosystems, and are trophically important conservation targets. Despite the designation of the Grand Canyon region as a natural landscape park and a World Heritage Site, human activities have eliminated or seriously reduced many of its large vertebrate predator populations, including Colorado pikeminnow, wolves, black and possibly grizzly bears, mountain lions, jaguars, bobcats, and Southwest river otter (Hoffmeister 1986, Minckley 1991). Southwest river otter was restricted to the Colorado River drainage and is now probably extinct.
