Marked Woodchucks were observed primarily at Pinecrest and Richmond for 5- to 160-min periods and/or "spotted" at single point locations during the afternoon and early evening. The Woodchucks used in the home range comparison analyses were observed an average of h with an average of five separate spottings. These observations were made over an average of 12 separate days per individual for a total of 117 h observation time and 129 spottings. To conform with ecological tradition, and thus permit comparisons with the existing literature, movement data are presented as home range sizes expressed as minimum home range areas. Data sufficient for statistical analysis were obtained only for the Woodchucks of the Richmond and Pinecrest interchanges because of sparse popula- tions at the other interchanges. Movements were quantified in two ways. The area of the home range, containing all locations at which a marked Woodchuck was observed over the season, was estimated using the minimum area method (Godfrey 1954). The area of a polygon formed by joining the outlying points (avoiding concave lines) at which an individual was observed was measured. "Range length", the straight-line distance between the two most distant observed locations of a Woodchuck, was also calculated because Godfrey (1954) found this value reached its maximum with fewer observed locations than did home range area. The data for home range area and home range length comparison included only those Woodchucks from Pinecrest and Richmond that had been observed on more than three separate occasions (a total of twenty-four individuals). To determine whether there were significant differences between male and female adults' and juveniles' home range sizes a Student-Newman- Kuels multiple r
