dc.description.abstractThe Grand River watershed drains 7,900 square miles in north central Missouri and southern Iowa, making it the largest Missouri watershed north of the Missouri River. Hundreds of miles of channels within the Grand River watershed were straightened in the early 1900s to facilitate agricultural development, causing progressive instability of the watershed, loss of high value habitat, and continually threatened infrastructure. Flood frequency and intensity have increased in recent years. The watershed historically contained diverse complexes of river/stream channel and oxbow habitats, floodplain forest and woodland, bottomland prairie, and terrace prairie and savanna that supported rich animal communities and provided many important ecological functions. Since the mid-1800s, thousands of acres of tallgrass prairie, wetland, and bottomland hardwood habitat have been lost. Over 300 miles of natural stream corridor were channelized, adversely impacting thousands of linear feet of riparian and aquatic habitat. Sediment deposition, erosion, and habitat degradation have increased in intensity, which are now serious problems. The scope of the study focused on achieving National Ecosystem Restoration (NER) benefits in accordance with Engineer Regulation (ER) 1165-2-501 because funding was provided through the USACE ecosystem restoration business line. Parts of the Lower Grand River sub-basin, one of three sub-basins within the Grand River watershed, have experienced the most ecosystem degradation and have the greatest restoration potential. The study scope focused on the Lower Grand River sub-basin in recognition of the significance of the ecological resources within the sub-basin, in particular a wetland complex of over 24,000 acres of state and federal lands including Pershing State Park, Fountain Grove Conservation Area (CA), Swan Lake National Wildlife Refuge (NWR), Yellow Creek CA, thousands of acres of NRCS conservation easement lands, and other private lands managed for conservation purposes. The study area lies is in the heart of what is known as the “Golden Triangle” by bird experts and waterfowl hunters because of its significance to migratory waterfowl and other bird species. The Golden Triangle lies near the border of the Central and Mississippi waterfowl flyways. Evidence of the significance of resources in the study area include its designation as an area of greatest continental significance to North American ducks, geese, and swan in the North American Waterfowl Management Plan, designation as an Important Bird Area by the Audubon Society, it is a focus area watershed in the NRCS Mississippi River Basin Healthy Watersheds Initiative, has received over $100 million in NRCS wetland easement investment, and contains a National River Inventory-listed segment of Locust Creek. The study area contains habitat supporting federally-listed bat species and is home to bald eagles. The institutional, public, and technical significance of the ecological resources within the study area is well established.en_US
