The Canadian High Arctic Tundra ecoregion encompasses most of the northern Arctic archipelago, from much of Baffin Island, Somerset Island, and Prince of Wales Island in the south, through all islands northward to the most northern island in Canada, Ellesmere Island. [3]
The adversity of soil and climatic conditions proves to low production levels, as well as little biomass accumulation due to slow rates of nutrient release in cold and wet soils, specifically as a result of limited nitrogen and phosphorus (Nadelhoffer et al. 1996) Additionally, there are low temperatures and strong winds in the tundra causing most vegetation to be dominated by woody plants ...

The ecoregion to the north is the 'High Arctic tundra' (colder and wetter), to the south is the Low Arctic tundra (warmer and wetter). [2] The bedrock under the western extent is Paleozoic and Mesozoic sedimentary rock with a relatively flat cover of glacial moraines and marine deposits.
