Abstract:

Wetlands are a major component of the prairie landscape in the Prairie Pothole Region of North and South Dakota and northeast Montana. Research suggests that the size, class, and geographic position of wetlands potentially influence their use by migratory waterfowl. During the late 1970's, the USFWS National Wetland Inventory (NWI) initiated a project to map the wetlands in North Dakota, South Dakota, and northeast Montana. This process resulted in the delineation of several million polygon, line, and point wetlands that included 250+ wetland habitat classes. We reprocessed the NWI digital data to create simple polygons that represent wetland basins. Riverine and lacustrine systems were reclassed to rivers and lakes, respectively. Complex palustrine wetlands were combined into a single polygons and reclassed using the most permanent water regime. Linear and point wetlands were buffered and along with simple palustrine wetlands, classed to their water regime.

Purpose:

In 1993, the US Fish and Wildlife Service, Region 6 Habitat and Population Evaluation Team (HAPET) initiated a modeling process to predict the distribution and density of breeding duck pairs in the Prairie Pothole Region portions of North and South Dakota and northeast Montana. Models developed by Cowardin (1995) to predict the potential of a wetland basin to attract breeding duck pairs were dependent on the size and class of individual wetlands. HAPET modified the models to incorporate a geographic component and identified digital NWI data as the wetland base on which to apply the models. Because the duck-pair predictive models were based on a 5 wetland class system (river, lake, semipermanent, seasonal, and temporary) and simple wetland basins, methodology was developed (basin rules) to manually reclass NWI wetlands (250+ classes) to the 5 class system similar to Stewart and Kantrud (1971), and combine complex wetlands into simple basins. HAPET integrated the "basin rules" into a GIS to automate the reclassification and dissolve process.

Process_Description:

The conversion of NWI wetland polygons into a 5 class, simple polygon representation was accomplished using Arc/Info Software. The 5 basin classes include: 1) River, 2) Lake, 3) Semipermanent, 4) Seasonal, and 5) Temporary. Several amls and INFO programs were developed by the HAPET Office to process the digital NWI data. The first step was to buffer line and point features, to give them area. Buffer distances were selected and applied based on data collected by L. Cowardin, USGS Northern Prairie Wildlife Research Center. Attributes for the point and line features were transferred to the respective buffer coverages which were then combined with the NWI polygon coverage. The series of amls and INFO programs used left/right polygon information to make decisions on whether individual arcs should be retained or removed based on the NWI "system" or "water regime" information. All riverine and lacustrine system polygons were retained as river or lake, respectively. Additionally, "intermittently exposed", "unconsolidated bottom", and 'impounded" water regime polygons were either combined with, or reclassed to a lake basin. Simple polygon palustrine wetlands were reclassified to the NWI water regime. The class of wetland basins that originated from several contiguous NWI palustrine wetland polygons was determined by the most permanent (i.e., order of permanence is semipermanent, seasonal, temporary) water regime from the contiguous polygons. The "basin rules" were developed with consideration to how waterfowl relate to wetlands, consequently, temporary wetlands were treated differently because they frequently do not contain ponded water. When a polygon of a temporary wetland regimes separated 2 wetland polygons of deeper water regimes in a complex basin, the temporary wetland polygon was retained. Additionally, excavated wetland polygon were always retained to eliminate the potential for large dendritic wetlands that would be created by combining natural wetland basins with ditch networks.
