This dataset is a component of a complete package of products from the Connect the Connecticut project. Connect the Connecticut is a collaborative effort to identify shared priorities for conserving the Connecticut River Watershed for future generations, considering the value of fish and wildlife species and the natural ecosystems they inhabit. Click here to download the full data package, including all documentation. This dataset represents the probability of occurrence of brook trout in headwater creeks based on current habitat and climate conditions. Brook trout are a representative species for cool/cold headwater creeks. This layer was derived from a model developed by Ben Letcher and associates at the USGS...

The North American distribution of Najas marina L. from 1863 to 2020 is presented in this dataset. Fields provided include georeferenced coordinates, dates of collections, collectors, and source herbaria. Data are housed in the U.S. Geological Survey's Nonindigenous Aquatic Species Database (nas.er.usgs.gov).
Background information. Settlement funds from the California Gulch Superfund site have been used to improve instream aquatic habitat and increase brown trout (Salmo trutta) populations in the Arkansas River. The upper Arkansas River Basin is a high-elevation mountain river that supports trout populations. Historically characterized by a relatively narrow channel with fast moving water, recent degradation of the upper Arkansas River due to historic land-use practices have contributed to an altered river channel and a decrease in important habitat features for trout, such as deep-water pools. This restoration project was designed to address three major issues: bank erosion, altered river channel morphology, and degraded...

The project consists of three distinct conservation projects: 1) the Sommers/Todd Place project, 2) the Scott Place project, and 3) the Duke Place project. All three projects combined encompass approximately 19,000 deeded acres located at two critical locations along the Green River in northern Sublette County and at an important corridor and buffer area between the Bridger-Teton National Forest and the Green River. Sommers/Todd Place: This portion of the porject encompasses over 5,100 deeded acres along the Green River. The ranches are contiguous and are located on both sides of the Green River. It is located along the west flank of the Pinedale Anticline natural gas field. The project includes a conservation...

Creates wetland habitats on public and private lands near the Green River. This project provides much needed habitat through the creation of 20 acres of wetland area, including a pond. Synopsis: This project will enhance swan habitat by creating 5-6 acres of additional shallow water foraging/nesting habitat adjacent to the New Fork River, and create nesting islands on the existing ranch reservoir. Introduction: Trumpeter Swans require shallow-water wetlands that produce extensive, luxuriant, and diverse stands of submerged aquatic vegetation. These kinds of wetlands, with some recognized physical and biological characteristics, fulfill functions important for swans of all age classes. The following information...

We provide an overview of research related to environmental effects of disposal of coal combustion residues (CCR) in sites in the United States. Our focus is on aspects of CCR that have the potential to negatively influence aquatic organisms and the health of aquatic ecosystems. We identify major issues of concern, as well as areas in need of further investigation. Intentional or accidental release of CCR into aquatic systems has generally been associated with deleterious environmental effects. A large number of metals and trace elements are present in CCR, some of which are rapidly accumulated to high concentrations by aquatic organisms. Moreover, a variety of biological responses have been observed in organisms...

The aquatic core networks is one of a suite of products from the Nature’s Network project (naturesnetwork.org). These datasets represent the aquatic core networks, which include lotic and lentic core areas and aquatic buffers. NOTE - The aquatic buffers dataset has been converted to integers and only contain values of 90 -100 (0.9 - 1) for online purposes, the original dataset is included in the download and contains all values. All datasets in this map are included in the download. The aquatic core networks represents intact, well-connected stream reaches, lakes, and ponds in the Northeast and Mid-Atlantic region that, if protected as part of stream networks and watersheds, will continue to support a broad...
This dataset represents the aquatic conservation projects within the Upper Tennessee River Basin generalized by Hydrologic Unit Code (HUC) 8 watershed. The information was obtained at the first annual meeting of the Upper Tennessee Imperiled Aquatic Species Strategy in 2016.

FY2017There is an increasing concern and need for the conservation of springsnails and other endemic mollusks and for conservation of the unique spring and springbrook habitats on which they depend (Hershler et al 2014; Abele 2011). Nationwide, several of these species have been listed as endangered or threatened under provisions of the ESA; others are candidates for federal listing or are undergoing review by USFWS for possible future listing actions. These species can be particularly susceptible to localized threats and specific knowledge necessary for effective site-based conservation is often limited or lacking.Springsnail are particularly susceptible to extinction because the entire population of any single...

Topock Marsh is a large wetland adjacent to the Colorado River and main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-average inflows and water depths in 2010-2011. Co-applicants Daniels and Haegele of FORT monitored Topock Marsh during the drawdown and immediately after, thus obtained information on immediate effects. However, stress from the drawdown may have a delayed effect on aquatic resources; additionally, significant changes to the infrastructure...

Nature’s Network Conservation Design depicts an interconnected network of lands and waters that, if protected, will support a diversity of fish, wildlife, and natural resources that the people of the Northeast and Mid-Atlantic region depend upon. This map serves as the “cover page” for the Nature’s Network (naturesnetwork.org) suite of products: it outlines some of the most important natural areas in the region and provides an entry point to learn more about the information used to identify them. The Conservation Design represents a combination of three Nature’s Network products: 1) the terrestrial core-connector network, 2) aquatic core areas, and 3) core habitat for imperiled species. The Terrestrial Core-connector...
This project involves the establishment of a 5.5 acre wetland for waterfowl and water bird habitat, including specific habitat developments for swans. Establishing secure, shallow water summer habitat is the most important management priority for swans in the upper Green River area.
