Abstract

Home ranges and dispersal of American martens (Martes americana) were determined in northeastern Oregon between 1993 and 1997 to provide managers with information necessary for developing management options to maintain habitat for viable populations. The average home range for males (2717 ha; SD = 1092.9; n = 10) was about twice that of females (1416 ha; SD = 744.3; n = 9). Home ranges were largely mutually exclusive for same-sex martens. Correlation analyses showed no significant linear relationships between the percentage of unharvested forest and home range size. Three juvenile martens (2 males, 1 female) that established home ranges outside the study area dispersed a mean of 33.3 km (range = 28 to 43.2 km).
