UMRR Long Term Resource Monitoring

The LTRM element is one of two components of the federally mandated Upper Mississippi River Restoration Program. A cooperative program between the U.S. Army Corps of Engineers, U.S. Geological Survey, U.S. Fish and Wildlife Service, U.S. Environmental Protection Agency, and the states of Illinois, Iowa, Minnesota, Missouri, and Wisconsin.

Hydrogeomorphic Classification and Conceptual Model

The overall objective of this study is to develop a hydrogeomorphic based conceptual model and hierarchical classification system for the UMRS. This model and classification system will build off the existing classification systems for the UMRS with a new aspect of potential for geomorphic change.

CarpDAT Invasive Carp Data Catalog

Four types of invasive carp fish species are currently found in the United States: black, grass, silver, and bighead carps. These species are fast growing, prolific feeders that out-compete native fish species and drastically alter the natural ecosystems they invade.

Understanding constraints on submersed vegetation distribution in a large, floodplain river: the role of water level fluctuations, water clarity and river geomorphology

Aquatic vegetation is a key component of large floodplain river ecosystems. In the Upper Mississippi River System (UMRS), there is a long-standing interest in restoring aquatic vegetation in areas where it has declined or disappeared. To better understand what constrains vegetation distribution in large river ecosystems and inform ongoing efforts to restore submersed aquatic vegetation (SAV), we...

Upper Mississippi River System Weighted Wind Fetch Analysis (1989, 2000, 2010/2011)

Wind fetch is defined as the unobstructed distance that wind can travel over water in a constant direction. Fetch is an important characteristic of open water because longer fetch can result in larger wind-generated waves. The larger waves, in turn, can increase shoreline erosion and sediment re-suspension.

Forest Landscape Ecology of the Upper Mississippi River Floodplain

Forests are the dominant land cover along the floodplain of the Upper Mississippi River System. These forests are primarily made up of relatively short-lived and rapidly growing species, such as willow, cottonwood, silver maple, green ash, American elm, but with inclusions of slower growing and longer-lived species, such as oak and hickory species.

Forest Canopy Gap Dynamics: Quantifying Forest Gaps and Understanding Gap-level Forest Regeneration

Floodplain forest is a major and critical component of the Upper Mississippi River System (UMRS). The current and future condition of floodplain forest on the UMRS is receiving increased attention from managers as the forest appears to be declining and not regenerating. A primary concern is invasive reed canarygrass (Phalaris arundinacea), Dutch elm disease (Ophiostoma ulmi and O. novo-ulmi), and...
