Mapping methods using extensive field data and three season Landsat and PALSAR imagery were developed to map wetland type and identify potential wetland stressors (i.e. adjacent land use) for the United States and Canadian Laurentian coastal Great Lakes. Mapped area included the coastline to 10 km inland to capture the region hydrologically connected to the Great Lakes. This effort represents the first comprehensive wetland delineation of the bi-national coastal Great Lakes using a consistent mapping technique. It includes detection of select invasive plant species (e.g. Typha spp., Schoenoplectus and Phragmites australis). Maps were developed in cooperation with the overarching Great Lakes Consortium plan to provide a comprehensive regional baseline map suitable for coastal wetland assessment and management by agencies at the local, tribal, state and federal levels and serve to augment previously completed Phragmites mapping funded by the USFWS and USGS Great Lakes Science Center. The project goal was to provide not only LULC baseline data at moderate resolution (20-30 m), but a repeatable methodology to monitor change into the future.
