英文摘要	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.
