The ELC comprises six nested levels; fromlargest to smallest scale these are: Site Region, System, Community Class, Community Series,Ecosite, and Vegetation Type (Lee et al 1998). The NAI study typically collected data at theCommunity Series level, however, data was collected at a few sites to the Ecosite andVegetation Type. Bakowsky (1996) defined Ecosite and Vegetation Type as follows:“Ecosite is a mappable landscape unit defined by a relatively uniform parent material, soil andhydrology, and consequently supports a consistently recurring formation of plant species whichdevelop over time (vegetation chronosequence).The Vegetation Type is part of an ecosite, andrepresents a specific assemblage of species which generally occur in a site with a more uniformparent material, soil and hydrology, and a more specific chronosequence”. Additionally,Vegetation Type is the basic plant community unit that is ranked in Ontario for conservationpurposes (Bakowsky 1996).39
