Alberta Species Conservation Atlas (ASCA)
The Alberta Species Conservation Atlas (ASCA) is an initiative led by the Applied Conservation Ecology laboratory that seeks to model the distribution and potential habitat for Alberta’s rarest taxa (500 plants, vertebrates, and invertebrates). By synthesizing information across species, ASCA will be used to rank – in a spatially-explicit manner – irreplaceability of Alberta’s places, thus helping to guide and prioritize conservation actions and land use decision-making associated with Alberta’s Land Use Framework. The Atlas will also provide rankings of species vulnerabilities to climate change and habitat fragmentation based on niche requirements and dispersal life history traits. This will be used to identify species in most need of assisted migration/colonization and locations where landscape connectivity necessitates restoration actions.

Conservation Planning in Northwest Alberta

A conservation plan for Northwest Alberta, Canada based on coarse and fine-filter conservation values.

Digital Atlas of Fruiting Shrubs

A digital atlas for 21 species of fruiting plants across the Lower Athabasca region of northeast Alberta south of Lake Athabasca.  Models were developed and used to map shrub presence, abundance (% cover) and fruit production for each species using  environmental predictors and field plot data (845 plots for presence; 335 plots for cover & fruit production).
