Resource Management

A variety of techniques are used to manage upland and wetland habitats on Waterfowl Production Areas (WPAs) within the Valley City Wetland Management district. These techniques vary depending on the specific goals and objectives desired for a particular habitat type. The three basic grassland habitat types are native grasslands, planted native grasslands, and planted dense nesting cover (DNC).

Prescribed burning and grazing are preferred treatments for native grasses. When timed properly, these techniques can improve vigor and modify species composition of warm and cool season native grasses. Haying and raking can also improve the vigor of native grasses and DNC. Haying and grazing activities are accomplished by issuing special use permits to private landowners.

Old stands of DNC are occasionally broken out and farmed for successive years and then seeded back to DNC or natives. Cooperative farming agreements are developed using private landowners as cooperators. Noxious weed management techniques include chemical application, mowing, sheep grazing, and biological controls such as flea beetles on leafy spurge.

Direct wetland management capabilities on WPAs are limited due to the inability to control or manipulate water levels.
