Climate directly affects the time of year, the length of the home range, and the use of the home range by the deer. In mild mid-west or southern climates whitetails may have home ranges no longer than two miles, and they often have traditional core areas. Deer in colder northern open prairie or foothill habitat may have larger home ranges (up to 120+ miles in South Dakota), and are less likely to have traditional core areas.
The climate and the number of bucks and does in the area affect the size of the home ranges of the buck, especially during the rut. Buck home ranges are generally larger than doe home ranges; often two or more times the size of local doe ranges; and the bucks’ use of their home ranges varies by the season. Bucks in mixed woodland/agricultural habitat in the mid-west may have home ranges of less than a thousand acres, to five or more square miles in size. During the summer adult bucks may use only a small portion of their home range. But, during the rut, adult buck home ranges often expand to include portions of several nearby doe and other buck home ranges.
Annual Home Range
The annual home range of each deer consists of the area used by the individual throughout the year. Non-migratory deer may spend both the summer and winter on the same home range. However, migratory deer in the northern states or mountainous regions may have two or more widely separated home ranges used during different times of the year. Dr.’s Larry Marchinton, Karl Miller and other researchers have found that the home ranges of whitetails are generally elongated, from two to four times longer than they are wide. However, deer in open coniferous or agricultural habitat may have irregular or circular home ranges.
