The Nature Conservancy (TNC) recently completed an unprecedented assessment of almost 14,000 dams in the Northeastern United States. The Northeast Aquatic Connectivity (NAC) project allows fisheries managers and other interested parties to assess dams at multiple scales based on their potential to benefit anadromous and resident fish species if removed or bypassed. This work has continued, with support from NOAA and USFWS, in the Chesapeake Bay watershed, where data refinements and further analysis have produced a web map and tool that allow users to interactively prioritize dams for mitigation at multiple scales and with varying criteria.The Southeast Aquatic Resources Partnership (SARP) has recently completed...
Unifying state-based stream classifications into a single consistent system, principal investigators at The Nature Conservancy developed a hierarchical classification system and map for stream and river systems for the Appalachian LCC that represents the region’s natural flowing-water aquatic habitats. This river classification information is needed to develop and implement instream flow standards and management recommendations so that environmental flows can become integral to all water management decisions from the onset.The study includes a report describing the methods used to evaluate and develop the classification system, a literature review of existing stream classifications, and a GIS stream data set. The...

The South Atlantic Landscape Conservation Cooperative (SALCC) project area supports a wide variety of critical estuarine and marine habitats. However, the existing maps of these resources were created at different scales and are housed in a variety of locations. This can be challenging for users and limits their utility for a regional approach to analysis. Looking across boundaries is important to understanding relative value when making habitat conservation decisions. With this project, The Nature Conservancy (TNC) proposes to: (1) develop a suite of regional natural resource maps for the South Atlantic; (2) create a report describing data source, analytical methods and mapping results that includes a summary of...
Consistent and accurate landscape datasets are important foundational products for ecological analyses and for understanding and anticipating the effects of climate change on forested, agricultural, and freshwater systems across the U.S. and Canada. The objective of this project was to extend an existing terrestrial habitat map of the north Atlantic U.S. to Atlantic Canada and southern Quebec, using and modeling field-collected data combined with national and provincial datasets. This GIS map 1) provides a foundation upon which further research, such as species vulnerability analyses, can advance, 2) allows each relevant state and province to identify terrestrial habitats consistently across borders, 3) allows for...

Assessing Future Energy Development across the Appalachian LCC used models that combined data on energy development trends and identified where these may intersect with important natural resource and ecosystem services to give a more comprehensive picture of what potential energy development could look like in the Appalachians. Ultimately this information is intended to support dialogue and conservation on how to effectively avoid, minimize, and offset impacts from energy development to important natural areas and the valuable services they provide.A final report from the study outlines the major findings of the potential footprint from coal, wind, and natural gas development. Models that depicts the probability...

Freshwater systems are critically imperiled and continue to be threatened by human encroachment and water development. The upper Gila River in New Mexico is one of the last unobstructed rivers in the Colorado River basin with a mostly intact native fish fauna, including two federally listed and one state-listed fish species. Kansas State University will develop methodologies or decision support tools to assess or evaluate current or existing resource management practices to learn and adapt to the effects of climate change on fish species. The researchers will investigate how the connectivity of the Gila River habitat impacts the fish population with respect to the behavior of native and non-native species.

The substantially natural hydrography of the upper Gila River supports one of the highest levels of aquatic and riparian biodiversity in the region, including the largest complement of native fishes and some of the best remaining riparian habitat in the lower Colorado River Basin. Native vegetation dominates the broad and structurally diverse floodplain, creating habitat for hundreds of birds and other wildlife. Two of the Gila’s fish species, spikedace and loach minnow, and a neotropical migratory bird, the southwestern willow flycatcher, are federally listed as endangered. The yellow-billed cuckoo, a candidate species for listing, nests in the Cliff-Gila Valley. Changes to the river’s hydrology, including peak...

In February 2014, taking action to implement a 2012 U.S.-Mexico agreement on the Colorado River known as Minute 319, International Boundary and Water Commissioners (IBWC) Edward Drusina and Roberto Fernando Salmon Castelo announced plans to move forward with a one-time pulse flow (a release of water into the Colorado River channel below the last dam on the River) as well as a five-year commitment by a coalition of Non-Governmental Organizations to deliver base flow water. Minute 319’s environmental water deliveries to the Colorado River Delta are intended to restore native riparian habitat along the river corridor, where invasive non-native saltcedar has displaced the native willow and cottonwood trees that provide...

Riparian vegetation provides crucial habitat for wildlife and is a high conservation priority for land managers throughout the Southwest but a central scientific challenge is to generate quantitative predictions of how changes in water availability will affect the amount and quality of riparian wildlife habitat. Researchers will study areas that have long-term datasets available (i.e., hydrological, geomorphological, biological), that characterize a broad range of riparian conditions found in the Southwest. Building on recently developed models funded by the USGS National Climate Change and Wildlife Science Center (NCCWSC), this work will link various hydrologic, geomorphic and habitat models to better understand...
