Book Description
Emergent sandbar habitat (ESH) in the Missouri River Mainstem System is a critical habitat element for several federally listed bird species: the endangered interior least tern (Sterna antillarum) and the threatened Northern Great Plains piping plover (Charadrius melodus). The Army Corps of Engineers (Corps) provides the primary operational management of the Missouri River and is responsible under the Endangered Species Act (ESA) to take actions within its authorities to conserve listed species. To comply with the 2000 USFWS BiOp and the 2003 amended USFWS BiOp, the Corps has created habitats below Gavins Point Dam using mechanical means. Initial monitoring indicates that constructed sandbars provide suitable habitat features for nesting and foraging least terns and piping plovers. Terns and plovers are using constructed sandbars and successfully reproducing at or above levels stipulated in the BiOp. However, whether such positive impacts will persist cannot yet be adequately assessed at this time.

Book Description
The U.S. Army Corps of Engineers (Corps) provides the primary operational management of the Missouri River Main Stem Reservoir System. Management of the Missouri River has generally reduced peak river flows that form and maintain emergent sandbar habitat. Emergent sandbars provide non-vegetated nesting habitat for the endangered interior least tern (Sternula antillarum athalassos) and the threatened Northern Great Plains piping plover (Charadrius melodus). Since 2000, piping plover nesting habitat within the Gavins Point Reach, Garrison Reach, Lake Oahe, and Lake Sakakawea has fledged the majority of piping plovers produced along the Missouri River system. Habitats within Lewis and Clark Lake have also recently become important plover production areas. Mechanical construction of emergent sandbar habitat (ESH) within some of these reaches within the Missouri River began in 2004. Through 2009, 11 sandbar complexes had been constructed (10 in Gavins Point Reach, 1 in Lewis and Clarke Lake) totaling about 543 ac of piping plover and interior least tern nesting habitat. ESH Construction has resulted in a net gain of tern and plover nesting habitat. Both terns and plovers successfully nest and fledge young on constructed sandbars, and constructed habitats were preferred over natural habitats. Natural processes may limit the viability of constructed sandbars as nesting habitat. Continued research is needed to identify if changes in constructed sandbar engineering and management increase the length of time constructed habitats effectively function as nesting habitat. However, the transfer of information from researchers to planners through technical research reports may not be timely enough to effectively foster the feedback mechanisms of an adaptive management strategy.

Book Description
Historically, the flow of sediment in the Missouri River has been as important as the flow of water for a variety of river functions. The sediment has helped form a dynamic network of islands, sandbars, and floodplains, and provided habitats for native species. Further downstream, sediment transported by the Missouri and Mississippi Rivers has helped build and sustain the coastal wetlands of the Mississippi River delta. The construction of dams and river bank control structures on the Missouri River and its tributaries, however, has markedly reduced the volume of sediment transported by the river. These projects have had several ecological impacts, most notably on some native fish and bird species that depended on habitats and landforms created by sediment flow. Missouri River Planning describes the historic role of sediment in the Missouri River, evaluates current habitat restoration strategies, and discusses possible sediment management alternatives. The book finds that a better understanding of the processes of sediment transport, erosion, and deposition in the Missouri River will be useful in furthering river management objectives, such as protection of endangered species and development of water quality standards.
