Abstract:
The ELC of Ontario was revised by the ELC Working Group in 2000 to better reflect the ELC system originally developed by Angus Hills (1959 and later revisions). This dataset was revised to take account new information and new technology, while maintaining Hills's original concepts. For further information on the rationale for the revisions, refer to Ecoregions of Ontario Modifications to Angus Hills Site Regions and Districts, Revisions and Rationale (Crins and Uhlig 2000), or the Ecological Land Classification Primer (Crins 2007). In 2002, the spatial data was updated using NRVIS drainage polygon data including islands from Great Lakes, St. Lawrence, and Ottawa River, and more detailed shoreline data. NTS mapping was also used to delineate the northern, eastern (Quebec border), and western (Manitoba border) boundaries of the province. This packaged dataset is classified into three hierarchical categories: Ecozones, Ecoregions, and Ecodistricts. Legislated or Legal Authority for Collection: None Additional Time Period Information: Final dataset was finished in early February 2003, with minor edits to correct mislabels and minor boundary errors. Several island polygons were missing in Georgian Bay and have been added on June 9, 2005.
