Document Summary
Identify recurring ecological patterns on landscape to reduce complex natural variation to reasonable number of meaningful units. System for getting consistent description, identification, classification, and mapping of ecological land units. Almost all of on is boreal forest, but highly diverse. Thus, on has its own ecological land classification system. Distinct ecological areas identified by geology, topography, soils, vegetation, climate, species, anthropogenic (human activity) factors that influence biotic composition or ecosystem processes within a unit. 1950s created by angus hills - research scientist, holistic and ecological approach to land use planning, focused on ecoregion, ecodistrict. 1990s revisions by burger based on vegetation succession patterns. 2000 - revised with new geographic info technology. Ecosection composed of ---> ecosites with similar ---> ecoelement. Can occur in multiple ecosites, ecodistricts based on comb of vegetation, soil. Forestry: old, mature forests (conifers) in north, deciduous in south. Relate to bedrock domain and long term climate patterns. Responds to global or continental cycles and processes.
