This study was carried out in TFL30 with the objectives to determine: 1) habitat use by a selected number of animal species (moose, furbearers & woodpeckers) along transects inhabited by American marten; and 2) species richness across successional stages. Eight transects were inventoried from 25 November 2006 to 12 February 2007. A total of 176 mammal tracks were recorded: 7 American marten, 28 fisher, 53 weasel, 8 coyote, 3 wolf, 38 squirrel, 37 snowshoe hare, and 2 moose tracks. Marten, fisher and squirrel tracks, woodpecker signs, observations of a late-successional bird complex (three-toed woodpecker, red crossbill, mountain chickadee, and red-breasted nuthatch), and wildlife trees were significantly (P < 0.05) more abundant than expected in excellent- and high- quality marten polygons, which corresponded to old-growth and mature forests, respectively. Moose tracks were significantly more abundant (P < 0.05) than expected in high-quality polygons. The species richness index was greater in excellentand high- quality polygons. The same conclusions were reached when pooling data from winters 2005-06 and 2006-07. Using marten as a late-successional species indicator allows one to identify sites that are significantly more valuable for late-successional biodiversity conservation. Knowing that martens exhibit great reluctance to cross openings or venture far from overhead cover, it is essential to properly manage landscapes inhabited by marten to maintain late-successional biodiversity in TFL30.
