Restoration of Upland and Riparian Vegetation Communities in the Sheyenne River Valley

Abstract

Degraded rangelands and riparian woodlands in eastern North Dakota are increasing in frequency. Two studies were conducted to address reduced forage quantity and quality and reduced regeneration of riparian tree and shrub species. Research objectives were to (1) analyze multiple pre-seeding treatments to determine impacts on rangeland production of interseeded native species; and (2) determine if fencing, weed-barrier fabric, mowing, or herbicide treatments can increase survivability of riparian tree and shrub seedling plantings. Pre-seeding treatments with herbicide showed significantly higher production of native species than the control. High-fencing/mowing treatment and high-fencing/weed-barrier fabric/herbicide treatment in riparian tree and shrub plantings resulted in significantly higher survival than the control. These findings will be used to develop future research and management strategies.
