Twenty-year Home-range Dynamics
of a White-tailed Deer Matriline



At the time of her death at 14.5 years old in 1988, D106 continued to migrate between the same winter and summer ranges she used when we first radio-tracked her as a 2-year-old in 1976 (Table 1).

A 10-year total of 154 locations of D106 on her summer range encompassed the space used by M112 during her tracking period (Table 1). The locations of the fawn-rearing sites used by D106 during the only 2 years when we determined them were centered 1 km apart. She raised her two fawns in the east part of her range during June-July 1979, while M112 raised her fawns in the north section (Fig. 3), the same area D106 had regularly occupied in 1976 (Fig. 2). After the death of M112, D106 used that area again, and as a primary area during fawning in 1988 (Fig. 4).
