Informing a conservation strategy for recovery of a federally endangered mussel (Tennessee Bean) in the Obed Wild and Scenic River, TN: Identifying contaminants of potential concern and evaluating effects of elevated toxicants on mussel recruitment

The Obed Wild and Scenic River, located on the Cumberland Plateau, is in a region where major declines and mass mortality of mussels have been observed. The Wild and Scenic River contains designated critical habitat for the federally endangered endemic Tennessee Bean ( Venustaconcha trabalis; aka Purple Bean). Water quality and habitat conditions in the Obed are critical factors for recovery of...

Aquatic Vegetation Monitoring

The Mississippi River is of global importance to persons and to the wildlife that live on and migrate along the river corridor. Data collected and processed by the Long-Term Resource Monitoring (LTRM) element of the Upper Mississippi River Restoration (UMRR) Program serves to help us understand, restore, and protect this remarkable ecosystem. The LTRM has collected aquatic and floodplain...

Constraints on Aquatic Vegetation and Restoration Potential of Aquatic Vegetation

Aquatic vegetation is a foundational element of life in aquatic systems, providing food and habitat for several species, and aquatic vegetation restoration is a high priority for Mississippi River managers. Understanding why plants grow in certain places, but not others is important for successful restoration efforts. This study evaluated the constraints on aquatic vegetation growth by using...

Shallow lake management enhanced habitat and attracted waterbirds during fall migration

Shallow lakes are a key resource for waterfowl species, so protecting and restoring these areas is of great importance to managing their populations. This study evaluated the effectiveness of management practices on shallow lakes and their influence on waterbird populations that depend on them. Researchers found that lake management actions increased the abundance of submerged aquatic vegetation...

Wetland Loss: Modeling Consequences for Waterfowl Production, Recreation Use, and Economic Opportunities

Amendments to the Clean Water Act in 1972 established federal jurisdiction over “navigable waters,” defined in the Act as the “waters of the United States.” A revised definition of the Waters of the U.S. rule took effect on 20 March 2023. However, various legal challenges precluded implementation of the new definition. On 25 May 2023, the U.S. Supreme Court, in the case of Sackett et ux. v...

Decision-support tool for managing endangered species in the face of uncertainty

Along the Santa Clara River in California, populations of the federally and state-listed Least Bell's Vireo ( Vireo bellii pusillus ) are recovering from near extirpation. Habitat protection and restoration, as well as reducing brood parasitism by Brown-headed Cowbirds ( Molothrus ater ), are thought to be the primary drivers of this recovery. The challenge going forward is to find the right...

Decision Support Systems

A Decision Support System (DSS) can be defined in many ways. The working definition the Upper Midwest Environmental Sciences Center (UMESC) uses is, "A spatially based computer application or data that assists a researcher or manager in making decisions ." This is quite a broad definition and it needs to be, as the possibilities for types of DSS are limited only by the user group and the developer...

River Productivity

Biological production represents the total amount of living material (biomass) that was produced during a defined period of time. This production is important because some of it is used for food and some is valued for recreation, it is a direct measure of total ecosystem processes, and it sustains biological diversity. Production is a measure of energy flow, and is therefore a natural currency for...

U.S. Fish & Wildlife Service - Comprehensive Conservation Plan

The Fish and Wildlife Service (USFWS) has been entrusted to manage our nation’s critical wetland resources. Due to conversion in industrial, residential, and agricultural uses, these wetlands have been disappearing at an alarming rate over the last one-hundred years. In order to better care for these resources, all of the refuges are developing long-term Comprehensive Conservation Plans (CCP).

Boater Compliance with Established Voluntary Waterfowl Avoidance Areas on the Upper Mississippi River

Disturbance to resting and feeding waterfowl on the Upper Mississippi River National Wildlife and Fish Refuge (Refuge) is of utmost concern to refuge managers. Voluntary Waterfowl Avoidance Areas (VWAA) have been established to reduce boating disturbance to migratory waterfowl on Navigation Pools 7 and 8 of the Upper Mississippi River. Ongoing boater compliance with the VWAA programs has been...
