“…Mean fire return intervals varied from 25-40 years before livestock grazing and fire suppression altered natural fire regimes (Barrett 2004). Elevation ranges for this forest type are from 915-1980 m. In northern Rocky Mountain forests, mixed-severity regimes occupied about 50% of the area now in national forest lands; low-severity regimes included about 30% of this area, and standreplacement regimes covered about 20% (Quigley et al 1996). http://www.ecologyandsociety.org/vol12/iss2/art15/ Mixed-severity fire regimes produced highly diverse forest communities containing abundant seral, fire-dependent species, including multi-aged stands with large, old, fire-resistant trees that are of great importance as wildlife habitat (McClelland 1979).…”

“…While these vary somewhat, efforts to measure these constructs involve combinations of process and profile indicators, and they involve quantitative and qualitative assessment tools. We describe each in brief detail below, for a more thorough review of these concepts see Nadeau et al (1999) or refer to the original broad-scale ecosystem assessment work that led to the merger of these concepts with the subject of resource-dependent communities (Kusel 1996, Quigley et al 1996, Harris et al 1998.…”

“…The Interior Columbia Basin Ecosystem Management Project (ICBEMP) defines community resilience as: the capacity of humans to change their behaviour, redefine economic relationships, and alter social institutions so that economic viability is maintained and social stresses are minimized" (Quigley et al 1996). Here, community resilience was measured at two different scales, the county level and the community level.…”

This paper describes the evolution of research on socio-economic indicators of community sustainability in several Canadian Model Forest locations since 1994. In the Foothills and Western Newfoundland Model Forests, we employed an "expert-driven" approach to indicator selection and reporting. We used census data to document change over time on key community profile variables such as age, employment, income, population mobility, education attainment, poverty, and real estate values. Objective measures of these variables were supplemented with personal interviews in order to construct a more dynamic picture of community well-being. The early work of our group focused primarily on "profile" indicators-essentially static, descriptive indicators that allow one to create a snapshot of a community in time. Work is currently underway on the next generation of socio-economic indicators we describe as "process" indicators. Process indicators deal more with causal affects than outcomes. They include things like sense of place or attachment to place (which has implications for population mobility and education attainment). Process indicators also include variables such as leadership, volunteerism, entrepreneurship, and social cohesion-all of which we are attempting to include in a combined measure of community capacity.Keywords: social indicators, community sustainability, model forest, forest-dependent communities, SIMFOR Cet article décrit l'évolution de la recherche sur les indicateurs socio-économiques de la durabilité des communautés pour certains endroits situés dans les forêts modèles canadiennes depuis 1994. Dans le cas des forêts modèles des Foothills et de l'ouest de TerreNeuve, nous avons utilise une approche « d'experts » dans le cas de la sélection et de la description des indicateurs. Nous avons utilisé les données des recensements pour documenter les changements au cours du temps pour les variables déterminantes du profil de la communauté tel l'âge, l'occupation, le revenu, la mobilité de la population, le niveau de scolarité, la pauvreté et la valeur immobilière. Les mesures objectives de ces variables ont été complétées par des entrevues individuelles de façon à élaborer un portrait plus dynamique de l'état de la communauté. Les travaux préliminaires de notre groupe se sont concentrés principalement sur les indicateurs du « profil », des indicateurs essentiellement statiques et descriptifs qui permettent d'établir un portrait instantané d'une communauté à un moment donné. Les travaux se poursuivent actuellement sur la prochaine génération d'indicateurs socio-économiques que nous décrivons comme des indicateurs du « processus ». Ces indicateurs traitent plus des causes que des conséquences. Ils comprennent des éléments comme le sens d'origine ou d'attachement à un endroit (ce qui a des impacts sur la mobilité de la population et le niveau de scolarisation). Les indicateurs du processus comprennent également des variables comme le leadership, le bénévolat, l'entrepreneurship et la cohésion sociale, que nous t...

Summary1. Climate change models consistently predict snow depth declines across the Northern Hemisphere. Snow depth has been linked to the demography of numerous species, and snow depth reduction is expected to affect the demography of some northern species. As many demographic studies depend on long-term population data that extend back beyond available sources of spatially continuous snow depth data, reliable hindcasting of snow depth surface maps is needed. 2. We developed a two-stage regression modelling approach to reconstructing historic snow depths using an existing and readily available spatiotemporal data set of daily meteorological variables across a large, heterogeneous landscape in North America from 1982 to 2003. The final model accounted for ecoregional differences and predicted snow depth as a function of elevation and total snowfall accumulation. 3. Model validations showed that the estimated snow depths were spatially and temporally accurate. 4. We demonstrate how to apply this model with ArcGIS to hindcast monthly and yearly sequences of high-resolution, spatially continuous surfaces of historic snow depths. We also illustrate the utility of the modelled snow depth surfaces for informing predictions of how changes in snow depth may influence the demography and habitats of snow-dependent and snow-restricted species by assessing the spatiotemporal stochasticity of snow conditions that potentially benefit wolverine Gulo gulo and the winter ranges, net energy costs and population growth of mule deer Odocoileus hemionus. 5. This model can be used to hindcast snow depth surfaces across similar regions; our simple twostage modelling approach can be applied to other regions where equivalent climate data are available. The resulting spatiotemporal snow depth surfaces estimated from this model can be linked to existing long-term wildlife population data sets to investigate the extent to which snow depth declines may regulate or limit populations.
