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...

All Conservation Design Elements identified through a multi-year conservation planning effort undertaken by the Appalachian Landscape Conservation Cooperative (LCC). These elements were identified by the program Marxan as meeting collective conservation targets. Datasets include a merged design of all five elements, individual element shapefiles, and a prioritization shapefile (Conservation Design elements outlined by the NatureScape Design that were then placed into a prioritization framework based on Margulis and Pressy 2000).

The Aquatic Core Networks, Unstratified is comprised of unstratified versions of Lotic Core Areas and Lentic Core Areas. These datasets are one of two versions of aquatic core areas that are part of a suite of products from Nature’s Network (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. Although the stratified version “Aquatic Core Networks” is considered by the planning team to be the primary version for users, this unstratified version is also made available for reference and use.These and other datasets that augment or complement the Aquatic...

The aquatic index of ecological integrity, version 3.1, was used as a mask to extract the aquatic classed from DSLland, version 3.1. Since streams flow into other habitats, such as wetlands, you will notice additional classes included here.
Approximately 298 acres of seasonal shallow water wetland habitat will be established or enhanced for water birds and waterfowl by constructing and repairing low level dikes and installing 6 water control structures. In addition, permanent water wetlands will be constructed enhance the wetland complex.

The Forest and Rangeland Ecosystem Science Center 's mission is to provide scientific understanding and the technology needed to support sound management and conservation of our nation's natural resources, with emphasis on western ecosystems. The scientists from FRESC capitalize on their diverse expertise to answer critically important scientific questions shaped by the equally diverse environments of the western United States. FRESC scientists collaborate with each other and with partners to provide rigorous, objective, and timely information and guidance for the management and conservation of biological systems in the West and worldwide. Research activities are concentrated in Washington, Oregon, Idaho, Nevada,...

The Muddy Creek watershed has been identified as having a high conservation value for Wyoming's fish species, big game crucial winter range and parturition areas, myriad neotropical migrant birds, abundant sage-grouse, and occupied habitat for the only population of Columbian sharp-tail grouse in Wyoming. Objectives of this project are to 1) Construct or maintain 4 vegetation exclosure projects, 2) Plant riparian vegetation, 3) improvement projects, monitoring of the area would be conducted to document the success of management efforts and identify areas where improvement is needed. Implementation of this project will benefit a diversity of fish and wildlife resources within an important ecosystem including...
Distributional patterns and species diversity of benthic insects in an alpine stream in Gunnison County, Colorado, USA were investigated on several levels of spatial scale, from faunal replacement over 1,000 vertical m to microdistribution within the stony substratum. Ecotones including zonation in terrestrial vegetation and in trout distribution did not appear to affect faunal replacement. Competition among congeners accounted for 7-30% of the cases, while in the majority of species, faunal replacement appeared to be associated with gradual changes in the physical gradient. Trout zonation may affect total numbers of insects, however, as the trout-free headwaters had two to six times higher insect densities. Microdistribution...

This project is an ongoing cooperative project to restore 6,300 feet of Battle Creek and replace two irrigation structures which currently block seasonal fish migration. This joint project will improve native Colorado Cutthroat fish habitat, improve thermal and low flow habitat, and reduce bank erosion. Restoration will include narrowing the channel to accommodate for 590 cfs bankfull flows; excavating pools and installing fish-hook vane structures to improve low flow trout habitat; and re-establishing riparian vegetation to prevent further erosion. At a minimum, the project will include the following: installing 10 fish-hook vanes, excavating 12 pools, installing bank full benches to narrow the channel, installing...
The restoration project constructed a low level dike, headwall, and head-gate at the mouth of the irrigation ditch to move the river back into its original channel. Phase II– The Sweetwater River jumped into an existing irrigation ditch creating a shortened braided channel (3,200 ft) and dewatering the historic single thread channel of 4,958 ft. The steepened channel created a head-cut in the main channel, causing channel incision and severe bank instability throughout the project area. The restoration project constructed a low level dike, headwall, and head-gate at the mouth of the irrigation ditch to move the river back into its original channel. Project completed August 2008. Approximately 12,100 ft of channel...

This dataset represents freshwater streams on the Chugach National Forest, Alaska. Streams were digitized from 1:31,380 orthophoto quads. Estuarine channel types may extend beyond shoreline. Selected stream arcs on Cordova Ranger District updated October and November 2002. Presence of fish species and stream class were updated.

Background information.—Historically, the Powell River supported abundant and diverse populations of freshwater mussels. In recent decades, mussel density and species richness have declined and many freshwater mussel species are listed as either State or Federally threatened or endangered species. Environmental degradation from coal mining has been identified as one of the drivers of this decline. An example is the 1996 Lone Mountain slurry spill that directly affected mussel populations, as well as their host fish species. Freshwater mussels feed by filtering small particles from water, thereby improving water quality and providing an essential ecosystem service in rivers and streams. Mussels also serve as a food...

In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality and ecological conditions change over time. To support that goal, long-term consistent and comparable ecological monitoring has been conducted on streams and rivers throughout the Nation. Fish, invertebrate, and algae data collected as part of the NAWQA program were retrieved from the USGS Aquatic Bioassessment database for use in trend analysis. Ultimately, these data will provide insight into how natural features and human...

The values for this dataset were extracted from the Index of Ecological Integrity, Region-wide, Version 3.2 for all aquatic systems. Updated 09/2017. The metadata for the original dataset is as follows:This dataset was last updated 02/2017. This version includes a new tidal restrictions metric that assesses the effect of undersized culverts and bridges on tidal regime.The previous version (3.1) was updated on 05/2016 by incorporating a revised version of the land cover classification, DSLland Version 3.1, developed by UMass, which included the addition of The Nature Conservancy’s Northeast lakes and ponds classification.
