Created from a collection of digital orthorectified images from aerial photographs of the study area acquired during July 1996 using Stewart and Kantrud classification system. Vegetation shape files of wetlands in the Cottonwood Lake Study Area were created in order to facilitate a better understanding of the influence of natural climate variability on plant communities of prairie wetland ecosystems. These wetland vegetation shape files are part of the Missouri Coteau Wetland Ecosystem Observatory database that is a collection of abiotic and biotic data documenting biotic and abiotic responses to long-term climate variability in the Prairie Pothole Region of the U.S. The Prairie Pothole Region has a naturally dynamic climate that is characterized by extended wet and dry periods, and its wetlands have spatially variable hydrologic and biotic traits. The Cottonwood Lake Study Area in Stutsman County, North Dakota contains wetlands representative of multiple positions along a hydrologic continuum, from groundwater recharge to discharge. The extensive history of data collection in the Cottonwood Lake Study Area provides a unique opportunity to assess the impact of climate variability on ecosystem health and productivity. The Cottonwood Lake Study Area is part of a complex of Waterfowl Production Areas in Stutsman County, North Dakota owned and managed by the U.S. Fish and Wildlife Service. 1996 ground condition Completed None -99.152104 -99.090117 47.111686 47.094615 The Cottonwood Lake Study Area is part of a complex of Waterfowl Production Areas in Stutsman County, North Dakota owned and managed by the U.S. Fish and Wildlife Service.

Stewart Harold A. Kantrud 1971 document Resource Publication 92 Washington, D.C. U.S. Fish and Wildlife Service, Bureau of Sport Fisheries and Wildlife https://pubs.er.usgs.gov/publication/rp92 Polygons were visually inspected with digital orthorectified aerial images to ensure similar data were used for classifying vegetation zones, and the correct wetland ID was used. Consistency of zone classification was reviewed among all years for each wetland. Attribute table was inspected to ensure all fields had valid values. Wetlands present in the Cottonwood Lake Study Area include: P1, P2, P3, P4, P6, P7, P8, P11, T1, T2, T3, T4, T5, T6, T7, T8, and T9. All wetlands had vegetation zones classified. Polygons were compared to digital orthorectified aerial images and National Agriculture Imagery Program (NAIP) imagery for positional accuracy. A formal accuracy assessment of the vertical positional information in the data set has either not been conducted, or is not applicable. Aerial photographs were georeferenced using on-the-ground control points and TNTmips GIS and image processing software. Control points consisted of 71 cm diameter metal circles (painted white) positioned over all groundwater wells at the site and at other locations to provide broad coverage across the site. Other control points (e.g., large rocks, woody vegetation) were also used to ensure a minimum of 6 control points for each image. The geographic locations of control points were determined using a Trimble GPS receiver. Unknown Wetland vegetation zones were digitized using ArcMap 10.4.1. Unknown Lab Global Change Master Directory EARTH SCIENCE SERVICES>DATA ANALYSIS AND VISUALIZATION>VISUALIZATION/IMAGE PROCESSING Vegetation zones were delineated from digital orthorectified aerial images of the study area (available at https://www.sciencebase.gov/catalog/item/5853fea1e4b0e2663625f35d) using ArcMap 10.4.1. Zones were broken down into six categories; open-water, deep-marsh, shallow-marsh, wet-meadow, exposed soil, and tree or shrub, see Stewart and Kantrud 1971. Delineation began with the interior most wetland zone, and outward to the wet meadow zone. If there were small communities of deep-marsh emergent vegetation within the open-water zone greater than one meter in diameter, they were identified before the open-water zone itself was identified. Wetlands were completed individually, and then merged into a single shapefile for each year. Wetland centers used to verify identification, see "Wetland Identifier Points" doi 10.5066/F7D798N0.
