Description: The DUC pre-settlement wetland extent (c. 1800) is a predictive historic wetland dataset that identifes are that are likely to have supported wetlands. The dataset was generated by combining OMAFRA County Soil Survey organic soils and poorly and very poorly drained mineral soils with OMNDM quarternary geology areas dominated by organic acculation, then the portions that were unlikely to be wetland due to their topographic position were removed using the OMNR provincial DEM and a net balance groundwater flow surface derived from MRI-DARCY. Bottomland features were not included in this dataset.
