Habitat and ecosystem data used to conduct a baseline survey of coastal habitat in the Canadian Great Lakes in support of the Great Lakes Water Quality Agreement (Annex 7, Habitat and Species). The baseline habitat survey integrates various internal and external data sources that are collected or produced by various government and non-government organizations and integrated into this dataset. The geographic scope of the survey focuses on the coastal margin (from the shoreline to approximately 2 kilometers inland) of the Canadian Great Lakes and connecting channels. The scope of the survey includes metrics for coastal wetland habitat, coastal terrestrial habitat, tributary habitat and habitat protection and restoration.
