Description
Ecological Land Classification (ELC) is an approach which endeavours to subdivide the landscape into significant ecological units and to organize complex interrelationships into identified geographical areas with similar properties. It is a hierarchical system that captures information at the following scales as per the Ecological Land Classification and Evaluation Reference Manual (1980):
Ecoprovince - >1:3 000 000
Ecoregion - 1:1 000 000 - 1:3 000 000
Ecodistrict - 1:250 000 - 1:1 000 000
Ecosection - 1:100 000 - 1:250 000
Ecosite - 1:10 000 - 1:20 000
Ecoelement - 1:1 000 - 1:5 000.
Note that the upper two levels are referred to as Natural Region and Natural Subregion in the more recent Ecological Land Classification reports. There are also some variations in this hierarchy for individual study areas. The data is available as TIFF image files packaged together with the reports and other supporting documents divided alphabetically.
