“…Our region-specific marten habitat suitability models showed a positive relationship between habitat and trapper harvest of martens, despite the use of overstory tree age as a surrogate for the structural characteristics that are considered key components of marten habitat (Ruggiero et al 1998, Payer and Harrison 2003, Bowman and Robitaille 2005. Both region-specific marten habitat suitability models identify several classes of habitat, ranked according to perceived quality for martens.…”

“…On a small scale, it appears that martens select forest stands that provide ample large downed wood and large dead and declining trees, in combination with adequate canopy closure , Bowman and Robitaille 1997, Payer and Harrison 2003, Mowat 2006. These structural features provide habitat for prey species, greater foraging efficiency, protective thermal microenvironments, and cover from predators (Corn and Raphael 1992, Thompson and Curran 1995, Wilbert et al 2000, Andruskiw et al 2008.…”

We investigated the relationship between trapper harvest of martens (Martes americana) and the quantity and spatial configuration of marten habitat on traplines in the eastern and western boreal forests of Ontario. We used region-specific habitat models to estimate the total amount of suitable marten habitat on each trapline, and the proportion of each trapline identified as suitable habitat in various patch size classes. To control for variability in trapper success not associated with habitat, we included an index of trapper effort, as well as variables related to access, temperature, and precipitation as covariates in our regression analyses. Region-specific habitat models identified a positive relationship between the proportion of suitable marten habitat on traplines (irrespective of patch size) and trapper success. Although there did not appear to be an effect of patch size on trapper success in the eastern study region, we observed an effect in the western region. Results from the western study region suggest that traplines with suitable habitat in patches ≥500 ha will have higher trapper success than traplines with similar proportions of suitable habitat but distributed in smaller patches. Our study was conducted in a forested landscape (80% of trapline area was forested). Therefore, our findings should not be applied to areas where suitable marten habitat lies in a matrix comprised of a significant amount of non-forested area.Key words: American marten, boreal forest, fragmentation, marten habitat, Martes americana, patch size, spatial configuration, trapper harvest, trapping RÉSUMÉ Nous avons étudié la relation entre le nombre de martres (Martes americana) piégées et le nombre d'habitats de la martre ainsi que leur configuration spatiale le long de lignes de trappage dans les forêts boréales l' est et de l' ouest de l'Ontario. Nous avons utilisé des modèles d'habitat spécifiques aux régions afin d' estimer le nombre total d'habitats adéquats de la martre le long de chaque ligne de trappage, ainsi que la proportion de chaque ligne de trappage identifiée comme étant adéquate selon différentes classes de dimension des parcelles. Afin de prendre en considération la variabilité du succès du trappage non associée à l'habitat, nous avons inclus un indice de l' effort du trappeur, ainsi que des variables reliées à l'accessibilité, la température et les précipitations en tant que covariables dans les analyses de régression. Les modèles d'habitat spécifique aux régions ont relevé une relation positive entre la proportion d'habitat adéquat de la martre le long des lignes de trappage (sans relation avec la dimension des parcelles) et le succès du trappeur. Même s'il ne semble pas y avoir d' effet de la dimension de la parcelle au niveau du succès du trappeur dans la région orientale sous étude, nous avons observé un effet dans la région occidentale. Les résultats de la région occidentale sous étude indiquent que les lignes de trappage dans les habitats adéquats constitués de parcelles ≥500 ha afficheront u...

“…American toads appeared to be unaffected by changes in habitat structure and composition resulting from basic silviculture by 20 years post-harvest. Marten responded somewhat positively to "basic 1" treatments within the context of the managed portion of the landscape, suggesting that silviculture provided habitat attributes, notably a higher conifer content, favourable to marten (e.g., Colgan 1987, Payer andHarrison 2003). Although marten used these more intensively managed stands, such evidence does not imply that marten populations can be sustained at high levels over the long term, if large areas of the boreal forest were managed intensively.…”

Much of the southern boreal forest is composed of second-growth stands that have been subjected to a variety of silvicultural treatments ranging from cut and leave to scarification, planting, and tending with herbicides. We have limited understanding of the effects that these treatments may have on wildlife species, as a result of changes to forest structures and species composition. Forest amphibians, generally, and the American marten (Martes americana) are species for which there has been long-standing concern about the effects of forest management. We examined the long-term effects at stand and landscape scales of a range of silviculture intensities on these species by comparing the relative abundances of some amphibians and habitat use by marten in forests that were about 32 to 50 years old. American toads (Bufo americanus) appeared to be unaffected by long-term changes in habitat structure and composition owing to silvicultural techniques. We observed lower relative abundance of wood frogs (Rana sylvatica) in treated stands 20 to 30 years old than in all other stands including uncut old forests. However, abundance in treated stands more than 32 years old did not differ from untreated or uncut stands. This effect may have resulted from lower moisture levels in treated young stands. Marten seemed to positively respond to post-harvest planting and tending treatments, suggesting that basic silviculture provided habitat attributes, notably a higher conifer content, which was favourable to marten.Key words: post-harvest silviculture, marten, wood frog, American toad, herbicide, boreal, woody debris, Ontario RÉSUMÉLa majeure partie du sud de la forêt boréale est composée de peuplements de seconde venue qui ont connu plusieurs traitements sylvicoles allant de la coupe à blanc au scarifiage, suivi de plantation et entretien au moyen d'herbicides. Nous comprenons en partie les effets que ces traitements pourraient entraîner sur les espèces fauniques, suite à des modifications de la structure et de la composition des peuplements. Les amphibiens du milieu forestier, de façon générale, et la martre d' Amérique (Martes americana) constituent des espèces pour lesquelles des études ont été entreprises depuis longtemps sur les effets de l'aménagement forestier. Nous avons étudié les effets à long terme au niveau du peuplement et de l' écosystème de l'intensité des travaux sylvicoles sur ces espèces en comparant l'abondance relative de certains amphibiens et de l'habitat utilisé par la martre dans des peuplements âgés de 32 à 50 ans. Le crapaud d' Amérique (Bufo americanus) a semblé ne pas être affecté par les changements à long terme de la structure et de la composition de l'habitat suite aux travaux sylvicoles. Nous avons observé une abondance relative plus faible chez la grenouille des bois dans les peuplements traités de 20 à 30 ans par rapport aux autres peuplements incluant les vieilles forêts non exploitées. Cependant, l'abondance dans les peuplements de plus de 32 ans n' était pas différente de celle des peu...

“…American marten (Martes americana) and fisher (Pekania pennanti), for example, are often associated with intact, late-successional forests (Thompson and Colgan 1994, Payer and Harrison 2003, Weir and Harestad 2003, Proulx 2006, Proulx 2011. These forests provide structural complexity and other attributes that are vital to the persistence of furbearers and other old-growth dependent species (Buskirk 1992, Payer and Harrison 2003, Proulx 2006. Other furbearer species, like Canada lynx (Lynx canadensis), may thrive across landscapes where different stages of successional forests are present; old-growth forests may provide habitat for denning and resting, while regenerating forests support prey (Hoving et al 2004).…”

“…Biologists and forest managers, however, recognize that many furbearer species avoid forest openings associated with industrial activity and habitat disturbance (Thompson and Colgan 1994, Hargis et al 1999, Potvin et al 2000, Fuller and Harrison 2005, Proulx 2009). Furthermore, fragmentation o f habitat at larger spatial scales may affect population productivity (Payer and Harrison 2003). The reduction and fragmentation of old forest across landscapes may have profound long-term effects on the abundance and persistence o f furbearer populations (Thompson 1994, Proulx 2000.…”
