Abstract

A radio-telemetry study of a resident population of Fisher and an invading population of Marten was conducted from August 1978 to August 1980, in the boreal forest of southeastern Manitoba. Two juvenile, female Fisher had winter ranges of 15.0 and 20.5 km2, while other juvenile females and males dispersed from the study area after their release. One juvenile, male Marten had a range of 9.6 km2 in early winter, while another wandered at random in late fall and early winter, but had a range of 8.1 km2 by the following spring. A juvenile, female Marten had seasonal ranges varying from 6.0 to 8.4 km2. A fire that swept through the study area in May 1980 perhaps caused one male Marten to disperse 61 km, while a female Marten did not alter her range during the two months that radio contact was maintained.

Key Words: Martes pennanti, Marten, Martes americana radio-telemetry, invading population, juveniles.
