During the last couple of decades, the distribution of the woodchuck (Marmota monax) appeared to be expanding southward in Arkansas (Tumlison et al. 2001). An increase in the frequency of new sightings led us to re-evaluate the present status of this species of squirrel in the state. The woodchuck is not easily confused with other mammals, therefore we sought records of sightings to update information about its distribution. Recent range expansion had been documented in southwestern Arkansas, so we placed notices in stores and advertised in local newspapers in that region to intensively seek new records of sightings from the public. Results of that effort, coupled with information gathered from a statewide survey of personnel of the Arkansas Game and Fish Commission, indicated that woodchucks are most common in the western Interior Highlands, and that the species apparently continues to expand its range southward in Arkansas.
