Draft supplemental environmental assessment for restoration of emergent sandbar habitat complexes in the Missouri River, North Dakota available for public review

Published April 9, 2019

Omaha, NE A draft supplemental environmental assessment (SEA) on the restoration of emergent sandbar habitat (ESH) complexes in the Missouri River, North Dakota is currently available for public review. The draft SEA evaluates the environmental impacts of removing and preventing vegetation on ESH located within the Garrison river reach and headwaters of Lake Oahe of the Missouri River, North Dakota.

Vegetation control would be implemented through the application of U.S. Environmental Protection Agency herbicides approved for use in aquatic systems (i.e., glyphosate and imazapyr) beginning in fall 2019 and continuing indefinitely into the future. Vegetation removal activities would include: disking, mowing, raking, burning, and removing large woody debris from the sandbars. The purpose of the proposed project is to benefit the federally endangered least tern and threatened piping plover by providing suitable habitat through the removal and control of vegetation of selected sandbars. 

The public is encouraged to provide comments on the draft SEA, which is available for viewing at:
