Summary
The first basin-wide map of large stands of invasive Phragmites australis (common reed) in the coastal zone was created through a collaboration between the U.S. Geological Survey and Michigan Tech Research Institute (Bourgeau-Chavez et al 2013). This data set represents a revised version of that map and was created using multi-temporal PALSAR data and Landsat images from 2016-2017. In addition to Phragmites distribution, the data sets shows several land cover types including urban, agriculture, forest, shrub, emergent wetland, forested wetland, and some based on the dominant plant species (e.g., Schoenoplectus, Typha). The classified map was validated using over 400 field visits.

Purpose
This map is an update of a previous circa 2010 map to help monitor invasive species and anthropogenic changes in the Great Lakes region. This work builds on a previous project, (Bourgeau-Chavez, et al., 2015 Development of a Bi-National Great Lakes Coastal Wetland and Land Use Map Using Three-Season PALSAR and Landsat Imagery. Remote sensing. doi: 10.3390/rs70708655.), and uses the same methods as described in noted citation. Maps are expansions of previously mapped areas to monitor land cover changes, specifically changes in invasive Phragmites caused by drivers such as treatments and water-level changes.
