Upper Boreal Highlands is an Alberta natural subregion that spans 2 ecoregions, none of which accounts for two thirds of it.
Boundaries digitised from the National Ecological Framework for Canada v2.2 (Ecological Stratification Working Group 1995), simplified to about 900 m for display: an outline is accurate to roughly a kilometre, not to the metre.
Ranges are recorded against ecoregions. This subregion crosses several, so there is no single species list that describes it. Follow the ecoregion your own site falls in.
