“…Larsen's interpretation suggests that martens in the study area were using the most advanced seres available, a conclusion supported by a majority of marten research (for reviews see Buskirk & Powell 1994, Buskirk & Ruggiero 1994). The more recent interpretation indicates that martens were using particular site type assemblages (i.e., closed spruce‐fir forests; sensu Bowman et al 1996). Regardless of interpretation, martens exhibited significant selectivity within the range of ‘second‐growth’ cover types.…”

“…Common herb layer species included Sphagnum spp., Clintonia borealis, Trientalis borealis, Streptopus roseus , and Aralia nudicaulis. (For a more detailed description of vegetation in the study area, see Bowman, Robitaille & Watt 1996). The region has a history (100–200 years) of clearcut logging, and stands were predominantly mid‐ to late‐successional (75% of stands were classed between 50 and 89 years; Ontario Ministry of Natural Resources, unpubl.…”

“…During our field surveys in June to August of 1994 and 1995, we determined the northeastern Ontario Forest Ecosystem Classification site types (NE-FEC) of each of the 565 model development plots (Bowman et al 1996). We characterized (1994).…”

“…Vegetation structure at used and random sites was statistically compared to derive the model. We also have tested an earlier version of the expert-based HSM (D'Eon and Watt 1994) for northeastern Ontario (Bowman et al 1996). However, we have not evaluated how these two modelling approaches were related (that is, how the two models performed on a set of the same stands), and we believe that this step is important to consider, as it would demonstrate the relationships that exist between the expert-based model and our field measurements of stand structure related to marten.…”

We used marten snow tracking data and a previously developed empirical habitat model from northeastern Ontario to validate a number of expert-based, non-spatial marten habitat models. In particular, we tested the non-spatial Ontario Wildlife Habitat Analysis Model, the Boreal East Habitat Suitability Matrix (including tests of both standard forest units and development stages), and Allen's (1982) HSI model. Marten habitat use as measured by tracks in the snow was consistent with predictions of all the expert-based models, suggesting that these models correctly characterized the standlevel forest cover selected by marten in winter. Suitability ranks for individual stands derived from standard forest units and development stages also were consistent with their use by marten. The empirical model was consistent with the expert-based models in that it considered suitable forest stands to be those with tall trees dominated by spruce (Picea spp.) and balsam fir (Abies balsamea) trees, with a large amount of coarse woody debris, and high canopy closure. Our findings suggested that the expert-based models were able to characterize stand structure used by marten despite some of the models using only inputs available from stand inventories. This was accomplished because stand structural elements such as coarse woody debris were integrated into OWHAM and HSM indirectly, through relationships with stand age and species composition.Key words: boreal forest, forest inventory, habitat, habitat suitability, guidelines, Forest Ecosystem Classification, landscape, Martes americana, resource selection, snow tracking, spatial autocorrelation, stand structure RÉSUMÉNous avons utilisé des données de pistes sur neige de martre et un modèle de qualité de l'habitat empirique existant du nord-est de l'Ontario pour valider quelques modèles non-spatiaux d'habitat de la martre et basés sur la littérature (experts). En particulier, nous avons testé le Modèle non-spatial d'Analyse de l'Habitat pour la Faune de l'Ontario, la Matrice de Qualité de l'Habitat Boréal Est (incluant les tests des unités forestières standard et des stades de développement), et le Modèle IQH d'Allen (1982). La distribution des pistes sur neige de martre correspondait aux prévisions de tous les modèles experts, ce qui suggère que ces modèles ont caractérisé correctement le couvert forestier des peuplements choisis par la martre à l'hiver. Les rangs de qualité des peuplements individuels dérivés des Unités Forestières standard ainsi que les stades de développement correspondaient également à leur usage par la martre. Le modèle empirique correspondait aux modèles experts en ce qu'ils considéraient les peuplements forestiers de qualité s'ils étaient constitués de grands arbres et d'une grande quantité d'épinettes (Picea spp.) et de sapins baumiers (Abies balsamea), de débris ligneux et d'une canopée fermée. Nos résultats suggèrent que les modèles experts étaient capables de caractériser la structure des peuplements utilisés par la martre en dépit du fait que certai...

“…These indices are generally assumed to have a positive linear relationship with the carrying capacity of the habitat. HSIs have been developed for the Fisher (Allen, 1983) and American Marten (Bowman, Robitaille & Watt, 1996). Allen's (1983) model was subsequently tested by Thomasma, Drummer & Peterson (1991), who found that Fishers selected those areas with HSI values greater than 0.8.…”

Landscapes are mosaics of habitat patches. The composition, configuration and connectivity of these elements changes in space and time as a result of ‘natural’ and human disturbance. Landscapes provide the ecological template for the life history and behavioural processes that determine animal spacing patterns. An understanding of the effects of landscape dynamics on mammal distributions is therefore vital if populations are to be managed effectively. Members of the Mustelidae present a considerable practical and theoretical challenge because of the great range of morphological, behavioural and ecological variation within the family. Habitat use data have been gathered only for a small number of Mustelidae species and most studies have been conducted with few individuals at small spatial scales and over relatively short time spans. Consequently, our knowledge of the landscape ecology of mustelids is very limited. Modelling can provide a strong conceptual framework for investigating mustelid‐habitat relationships. We review the potential of different modelling approaches for analysing the influence of landscape dynamics on the distributions of mustelids.
