This study area consists of a 10-km inland buffer of the U. S. Great Lakes shoreline. Islands within the lakes were included in this invasive Phragmites mapping project where remotely sensed imagery scenes were available.

Maps of areas greater than 0.2 hectare (0.5 acre) dominated by invasive Phragmites australis were created for the coastal region (shoreline to 10 km inland) of the United States side the Great Lakes and connecting water ways. The maps were developed using unsupervised/supervised classification methods and ground truth data collected during 2010 and 2011 in conjunction with multi-season ALOS PALSAR imagery (for the remote sensing-based iterative classification process), as well as through the interpretation of aerial photography to reduce classification confusion. Overall classification accuracy compared to field data for mapping was approximately 86%.

This network of inland streams, wetlands and water bodies is a composite of two layers from the National Hydrography Dataset Plus (NHD+ flow lines and water bodies), and all available wetlands from the National Wetlands Inventory (NWI) and Wisconsin Wetlands Inventory (WWI). In combination, these layers provide a network template of inland corridors for assessing relative vulnerability to future invasions of Phragmites.
