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.

These files were used to construct corridors estimating the extent of new coastal corridors exposed by reduced lake levels. They are included here to show the available horizontal extent of lidar-derived topo-bathymetric data and thus explicitly identify gaps and limitations of predicted corridor extents under various reduced lake level scenarios. In addition, these files provide users with a background layer that depicts the topographic variability of the submerged near-shore lake bed and terrestrial landscape.These files are 5m grid representations of the hydrographic and topographic data collected by the CHARTS system along the coasts of the U.S. sides of Lake Michigan, Lake Huron, Lake St. Clair, Lake Erie,...

An extreme flood in 2016 caused widespread culvert blockages and road failures across northern Wisconsin, including extensive damage along steep tributaries and ravines in the Marengo River watershed. Along with the flooding, there were fluvial erosion hazards (FEH) associated with a large amount of erosion in headwater areas. Of special concern were FEHs associated with gullying, loss of wetland storage, and valley-side mass wasting. In 2020, a pilot study was begun to map and classify ephemeral and perennial streams and wetlands in terms of their susceptibility to fluvial erosion hazards. This study combines rapid geomorphic field assessments of river corridor erosion and coupled sediment and debris delivery with...

Up to 12 different prey fish species were sampled with a 12-m bottom trawl during April, July, and September along two Lake Huron transects (Thunder Bay, Hammond Bay). At each transect in each month, two replicate 10-min tows were conducted at each of three depths (18, 46, 82 m) during the day and night. Once the fish were onboard in a given tow, they were sorted to species, weighed (in aggregate), and up to 50 individuals per species were measured to the nearest total length.

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%.

NOTE: A more current version of the Protected Areas Database of the United States (PAD-US) is available: PAD-US 2.1 https://doi.org/10.5066/P92QM3NT. The USGS Protected Areas Database of the United States (PAD-US) is the nation's inventory of protected areas, including public land and voluntarily provided private protected areas, identified as an A-16 National Geospatial Data Asset in the Cadastre Theme (https://communities.geoplatform.gov/ngda-cadastre/). The PAD-US is an ongoing project with several published versions of a spatial database including areas dedicated to the preservation of biological diversity, and other natural (including extraction), recreational, or cultural uses, managed for these purposes...

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.

These data represent coastal corridors exposed by lake levels reduced from mean 2009 water surface elevations. These elevations were established by values published by the United States Army Corps of Engineers (USACE), and based on a network of multiple gages within each lake. The corridors were derived from two data sources: 5-m resolution lidar-based topo-bathymetry produced by the USACE Joint Airborne Lidar-Based Technical Center of eXpertise (JALBTCX) and the National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center, and bathymetric contour lines produced by the NOAA Great Lakes Environmental Research Laboratory (GLERL). The JALBTCX lidar-based topo-bathymetry were used to produce representations...

Gap Analysis Project (GAP) habitat maps are predictions of the spatial distribution of suitable environmental and land cover conditions within the United States for individual species. Mapped areas represent places where the environment is suitable for the species to occur (i.e. suitable to support one or more life history requirements for breeding, resting, or foraging), while areas not included in the map are those predicted to be unsuitable for the species. While the actual distributions of many species are likely to be habitat limited, suitable habitat will not always be occupied because of population dynamics and species interactions. Furthermore, these maps correspond to midscale characterizations of landscapes,...
