Agricultural and residential development, as well as recreational activity, has altered the wildlife community of the Monument. Mule deer are common. Red foxes, coyotes, badgers, cottontail rabbits, and yellow-bellied marmots are upland residents. River otter, beaver, muskrat, mink, and other furbearers are found in and around Hagerman’s ponds, marshes, and waterways.
