Map of the risk of current fish habitat degradation of inland streams of the Central Mississippi River States.
The Central Mississippi River states contain the confluences of the Upper Mississippi River with the Ohio, Missouri, and Arkansas rivers. Alteration of these large rivers for transportation and flood control has substantially altered their ecological characteristics, eliminating natural floodplains, sandbars, and meanders, and impeding fish migration routes. Other major tributary rivers include the Tennessee, Cumberland, Kentucky, and Osage, all very large rivers in their own right. Large reservoirs are common in the landscape of this region and have increased recreational opportunities for sportfish as well as many other activities, but typically suffer from dissolved oxygen issues in both the reservoirs and in...
A. Pervasive disturbances: The most common disturbances based on total stream length in a given region. Top five overall most pervasive disturbances to all stream reaches, regardless of stream size and across all spatial scales (ranked highest first): Impervious surface cover Pasture and hay land use Population density Road density Low intensity urban land use Top three most pervasive disturbances to creeks (<100 km 2 watersheds) across all spatial scales : Impervious surface cover Population density Road density Top three most pervasive disturbances to rivers (>100 km 2 watersheds) across all spatial scales : Pasture and hay land use Upstream dam density Mine density.
