|This study was carried out from 2 February to 3 March, 2006 in Supply Block F of the Prince George TSA. It aimed to assess predictive winter habitat models for American marten (Martes americana), fisher (Martes pennanti) and wolverine (Gulo gulo), and to inventory species living in sympatry with these mustelid. A total of 14,955 m were inventoried across polygons of diverse quality, as determined by the different habitat models developed for the above-noted species. Seventeen marten tracks were recorded, all in excellent-quality polygons. The observed frequency of tracks per polygon type was significantly different (P < 0.001) from random. These polygons corresponded to late-successional, coniferous and coniferous-deciduous stands, with 40-65% canopy closure, tree dbh >29 cm, and basal area ranging from 30 to 40 m2/ha. Eleven fisher tracks were recorded in excellent- (10 tracks) and high- (2 tracks) quality polygons. Because of the small sample size, a significant difference could not be established between polygon types (P = 0.2). From a structural point of view, these polygons corresponded to young (6 tracks) and mature (6 tracks) stands. No wolverine tracks were found. A total of 706 tracks of furbearers and ungulates were also recorded in Supply Block F. Species diversity and richness were similar between polygon types, but excellent-quality polygons for marten distinguished themselves from other types by the exclusive presence of highly discriminate species such as marten, fisher and woodpeckers. Because marten is much more selective than fisher in the selection of its winter habitats, it is suggested that its model be used over that of fisher for the identification of leave areas in managed landscapes. In order to take into consideration annual variations in environmental conditions and species distributions, it is recommend that marten and fisher track inventories be repeated in winter 2007, in the eastern and northern portions of Supply Block F.|
