Stream channel geomorphology influences mussel abundance in southern Appalachian streams, U.S.A.
We quantified freshwater mussel abundance and species richness and their physical habitat at 24 sites in eight streams in southern Appalachian catchments in 2000 and 2001. In addition, we modelled site-specific hydraulic parameters during summer baseflow and bankfull stages to estimate high- and low-discharge conditions, respectively. Mussel abundance was related to stream geomorphology, whereas richness was related to stream size. Baseflow habitat parameters explained only minor variation in abundance or richness, and both measures were highly correlated with mean current velocity or stream size. Bankfull shear stress composed a relatively low proportion of overall mussel habitat variability, but it accounted for significant variation in abundance and richness. Mussel abundance was highly variable at sites subject to low-shear stress during spates, whereas abundance always was low at sites subject to high-shear stress. These data suggest that habitat conditions during floods, rather than those at summer baseflow, limit the abundance of mussels in Appalachian streams. These data also suggest that mussel abundance and assemblage structure may be sensitive to any changes in channel geomorphology and hydraulic conditions that might result from land use in the catchment.
Stakeholder participation for environmental management: A literature review
The complex and dynamic nature of environmental problems requires flexible and trans- parent decision-making that embraces a diversity of knowledges and values. For this rea- son, stakeholder participation in environmental decision-making has been increasingly sought and embedded into national and international policy. Although many benefits have been claimed for participation, disillusionment has grown amongst practitioners and stakeholders who have felt let down when these claims are not realised. This review first traces the development of participatory approaches in different disciplinary and geograph- ical contexts, and reviews typologies that can be used to categorise and select participatory methods. It then reviews evidence for normative and pragmatic benefits of participation, and evaluates limitations and drawbacks. Although few of the claims that are made have been tested, there is evidence that stakeholder participation can enhance the quality of environmental decisions by considering more comprehensive information inputs.
Pragmatic population viability targets in a rapidly changing world
To ensure both long-term persistence and evolutionary potential, the required number of individuals in a population often greatly exceeds the targets proposed by conservation management. We critically review minimum population size requirements for species based on empirical and theoretical estimates made over the past few decades. This literature collectively shows that thousands (not hundreds) of individuals are required for a population to have an acceptable probability of riding-out environmental fluctuation and catastrophic events, and ensuring the continuation of evolutionary processes. The evidence is clear, yet conservation policy does not appear to reflect these findings, with pragmatic concerns on feasibility over-riding biological risk assessment. As such, we argue that conservation biology faces a dilemma akin to those working on the physical basis of climate change, where scientific recommendations on carbon emission reductions are compromised by policy makers. There is no obvious resolution other than a more explicit acceptance of the trade-offs implied when population viability requirements are ignored. We rec- ommend that conservation planners include demographic and genetic thresholds in their assessments, and recognise implicit triage where these are not met.
Appalachian LCC - First Annual Report 2011
This report details the formation and achievements of the Appalachian LCC in its first year. During this year, the Appalachian LCC set in place the governance and decision-making Interim Steering Committee body, identified partners and partnerships that would be critical to achieving its mission, and made a number of important decisions to set the direction and tone of the partnership. Each of these decisions is leading to progress toward the primary goal of improving the science foundation for conservation work in the Appalachians.
Full Proposal - A Stream Classification System for the Appalachian Landscape Conservation Cooperative
The goal of this project is to develop a hierarchical classification for stream and river systems within the Appalachian Landscape Conservation Cooperative (LCC). This classification system will identify and consistently map ecologically similar types of rivers and streams using a flexible hierarchical set of geomorphic and hydrologic variables deemed appropriate for classification by the participating states and relevant to the spatial scale of management.
Full Proposal: Assessing Future Energy Development Across the Appalachian Mountains
Scientists will employ land use change build-out scenaria for future energy development demand to quantify future impacts on forest habitats across the Appalachian LCC. We propose to create maps of wind, oil and gas, and coal development potential for the entire study area and use these maps and published projections from federal and state land management agencies to model future build-out scenaria.
