“…They offer relatively little ground structural complexity for prey and provide Fishers with little protection against weather and predators (G. P., unpublished). This finding is in agreement with previous studies in various ecozones (Proulx 2006;lancaster et al 2008;Weir and Corbould 2010).…”

Late-winter habitat use by the Fisher, Pekania pennanti (Erxleben, 1777) in northwestern Saskatchewan was assessed in February 2009, 2011, and 2012. A total of 78 Fisher tracks were recorded over 60 300 m of snowshoe surveys. Fisher tracks were significantly less frequent than expected in Tamarack (Larix laricina [Du Roi] K. Koch) stands with > 40% crown closure and mainly 0–10 m trees (P < 0.05) and in open areas. Fishers used other habitat types equal to availability, including muskeg and coniferous, mixed, and deciduous forest stands. Maintaining mosaics of forest stands of different seral stages interspersed with muskeg would meet the late-winter habitat needs of Fishers in the Boreal Plains Ecozone of northwestern Saskatchewan.

“…Earlier research has suggested that partial cuts maintain some of the habitat requirements of wildlife species of high Aboriginal importance, like marten (Martes americana) or fisher (Pekania pennanti), which avoid recent clearcuts (Weir andCorbould 2010, Cheveau et al 2013). Moreover, partial cuts could allow for the restoration or maintenance on the landscape of tree species of high value for Algonquin people, like eastern white-cedar (Thuja occidentalis) (Larouche et al 2007) or white pine (Pinus strobus) (Burgess et al 2005).…”

The dominant management strategy in boreal forests-aggregated clearcuts (AC)-faces increased criticism by various stakeholders, including Aboriginal people. Two alternative strategies have been proposed: dispersed clearcuts (DC) and ecosystem-based management (EM). We modelled the long-term and landscape-scale effects of AC, DC, and EM on a set of indicators of sustainable forest management relevant to an Aboriginal community's values: (1) forest age structure; (2) spatial configuration of forest stands; (3) road network density; and, (4) forest habitat loss to clearcuts. EM created a forest age structure closer to what would result from a natural disturbance regime, compared to AC and DC. Cut blocks were more evenly distributed with EM and DC. The road network density was lower and increased slower with EM, thus reducing the potential for conflicts between forest users. Under EM, a higher forest cover was maintained (and thus potential wildlife habitat) than in AC or DC. The EM scenario provided the best outcome based on the four measured indicators, partly because the constraints imposed on the modeling exercise led it to harvest less than the other scenarios. Annual allowable cut should thus be a key factor to consider to ensuring better compliance with Aboriginal criteria of sustainable forest management.Key words: modeling; landscape; Indigenous people; forest management; social acceptability RÉSUMÉ La principale stratégie d'aménagement en forêt boréale-les coupes agglomérées (CA)-est de plus en plus critiquée par plusieurs parties prenantes, incluant les peuples autochtones. Deux stratégies alternatives ont été proposées : les coupes dispersées (CD) et l'aménagement écosystémique (AE). Nous avons modélisé les effets à long terme et à l' échelle du paysage de CA, CD et AE sur un ensemble d'indicateurs d'aménagement forestier durable liés aux valeurs d'une communauté autochtone : (1) la structure d'âge de la forêt; (2) la configuration spatiale des peuplements forestiers; (3) la densité du réseau routier; et, (4) la perte d'habitat forestier due aux coupes totales. AE a créé une structure d'âge plus proche de celle qui résulterait d'un régime naturel de perturbations, comparativement à CA et CD. Les blocs de coupe étaient répartis plus uniformément sur le territoire avec AE et CD. Le réseau routier était moins étendu et se développait moins vite avec AE, réduisant ainsi le potentiel de conflits entre usagers de la forêt. AE a aussi maintenu plus de couvert forestier (et donc plus d'habitat faunique potentiel) que CA ou CD. Le scenario AE a obtenu de meilleurs scores pour les quatre indicateurs mesurés, en partie parce que les contraintes imposées à l' exercice de modélisation ont résulté en moins de coupes que dans les autres scénarios. La possibilité forestière annuelle devrait par conséquent être un facteur clé à considérer pour assurer une meilleure conformité aux critères autochtones d'aménagement forestier durable.

“…Structure and cover have been considered critical elements for fisher habitat (Raley et al, 2012;Weir and Corbould, 2010;Truex and Zielinski, 2013). In our initial models to characterize structure, the most supported model was the landscape model with a high proportion of stands with high canopy cover.…”

a b s t r a c tThe fisher (Pekania pennanti; formerly known as Martes pennanti) is a North American endemic mustelid with a geographic distribution that spans much of the boreal forests of North America. In the Northern Rocky Mountain (NRM) fishers have been the focus of Endangered Species Act (ESA) listing decisions. Habitat studies of West Coast fishers in California have consistently identified late-successional forests as important, providing direct implications for forest management and fisher conservation. In the NRM range very little is known about the habitat selection patterns of fishers relative to forest age and species composition, yet ESA petitioners have repeatedly listed habitat loss and destruction as the primary threat to fisher persistence. Between 2002 and 2006 we studied NRM fishers in the Clearwater sub-basin and eastern slope of the Bitterroot-Selway Ecosystem in Idaho and Montana. We used radio-telemetry locations from collared fishers to document fisher habitat use. We developed candidate models describing tree size, species composition, canopy closure, structural diversity, and topography to assess patterns of habitat selection relative to topographic and vegetative predictor variables measured at both stand and landscape scales. Support for these models was evaluated using Akaike Information Criteria. Fishers disproportionately used both stand sites and regional landscapes characterized by large diameter trees and avoided areas with ponderosa (a shade-intolerant species characteristic of xeric sites in the NRM) and lodgepole pine according to our best supported model. These results are consistent with other studies in the western US and Canada where large trees were deemed important, although we show that this selection in the Rocky Mountains occurs at multiple scales. These results highlight the importance of late-successional forests, consistent with a recent conservation strategy for fishers, and the importance of both stand-and landscape-level factors when directing forest management of fisher habitat in the US Rocky Mountains.Published by Elsevier B.V.
