Final Report: A Stream Classification for the Appalachian LCC
-
A classification system and map was developed for stream and river systems in the Appalachian LCC region, encompassing parts of 17 states. The product is intended to complement state-based stream classifications by unifying them into a single consistent system that represents the region’s natural flowing aquatic habitats. The results can be used to understand ecological flow relationships and inform conservation planning for aquatic biodiversity in the region.

Stream Impacts from Water Withdrawals in the Marcellus Shale Region
-
The Appalachian LCC provided a grant to Cornell University Environmental Engineers to study how the region’s surface freshwater supply – and the health of natural systems delivering this resource – have been impacted and may be altered in the coming years under increasing water withdrawals.

Riparian Restoration Decision Support Tool
-
An innovative riparian planting and restoration decision support tool is now available to the conservation community. This user-friendly tool allows managers and decision-makers to rapidly identify and prioritize areas along the banks of rivers, streams, and lakes for restoration, making these ecosystems more resilient to disturbance and future changes in climate. It will also help the conservation community invest limited conservation dollars wisely, helping to deliver sustainable resources.

Riparian Restoration Decision Support Tool Fact Sheet
-
An innovative web-based tool - funded by the Appalachian Landscape Conservation Cooperative (LCC) and developed by researchers from the U.S. Forest Service and the University of Massachusetts - is allowing managers to rapidly identify high-priority riparian targets for restoration to make more resilient in preparation for changes in future climate. The Riparian Restoration Prioritization to Promote Climate Change Resilience (RPCCR) tool identifies vulnerable stream and riverbanks that lack tree cover and shade in coldwater stream habitats. By locating the best spots to plant trees in riparian zones, resource managers can provide shade that limits the amount of solar radiation heating the water and reduces the impacts from climate change. This well-established management strategy will benefit high-elevation, cold-water aquatic communities.

Stream Classification System for the Appalachian Landscape Conservation Cooperative
-
Stream classification information is essential to develop and implement flow standards and water management recommendations that will sustain aquatic biodiversity. Unfortunately, standardized information was lacking for the Appalachian landscape. The goal of this project was to develop a state-based, consistent stream classification system for aquatic ecosystems in the region. 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 aquatic habitats.

FishBrain and U.S. Fish and Wildlife Service Partner to Create App-powered Citizen Science Engagement Opportunity Tracking Endangered Species
-
The U.S. Fish and Wildlife Service – the federal government agency dedicated to the conservation of fish, wildlife, plants and their habitats – has teamed up with FishBrain – the world’s largest free-to-use app and social network for anglers – to launch a new feature of the app that will help the American public identify and document threatened, endangered and candidate species.

Population Performance Criteria to Evaluate Reintroduction and Recovery of Two Endangered Mussel Species, Epioblasma brevidens and Epioblasma capsaeformis
-
Genetic and demographic modeling of two endangered mussel species, Epioblasma brevidens and E. capsaeformis, in the Clinch River, U.S.A., was conducted to determine quantitative criteria to evaluate performance of extant and reintroduced populations. Reintroduction modelling indicated that the initial population size created during a 5 year build-up phase greatly affected final population size at 25 years, being similar to the population size at the end of the build-up phase, especially when population growth rate was low. Excluding age 0 individuals, age 1 juveniles or recruits on average comprised approximately 11% and 15% of a stable population of each species, respectively. Age-class distribution of a stable or growing population was characterized by multiple cohorts, including juvenile recruits, sub-adults, and adults. Because of current barriers to dispersal and the low dispersal capability of some mussel species, reintroductions will play a prominent role in restoring populations in the United States.

Plan for the Population Restoration and Conservation of Imperiled Freshwater Mollusks of the Cumberland Region
-
The goal of this Plan is to provide a framework for the restoration of freshwater mollusk resources and their ecological functions to appropriate reaches of the Cumberlandian Region through the reintroduction, augmentation (R/A) and controlled propagation of priority mollusks. The Plan prioritizes propagation and R/A activities for Region mollusks and provides guidelines for resource managers and recovery partners. The Plan is not a legal document and is not intended to replace or supersede published recovery plans for listed mollusks.
