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...
We will develop SMART-SLEUTH, an advanced spatially explicit modeling framework designed to augment the current SLEUTH model with sophisticated smart-growth capabilities. Based on the latest version of SLEUTH, we will create an open-source GIS-enabled software package that will implement SMART-SLEUTH with advanced modules and tools for evaluating, predicting, and visualizing smart growth scenarios and outcomes. In this software package, a more user friendly Graphic User Interface (GUI), a multi-level automatic calibration approach built on machine learning algorithms, and new spatial landscape metrics for quantifying land change patterns will provide enhanced support for complex model configuration, calibration,...

The Southeast Aquatic Resource Partnership will direct development of science-based instream flow information for water resource managers and policy makers of the SALCC. The outcome of this project will help inform water resource managers and policy makers about flow requirements of streams, rivers, and estuaries of the SALCC region. It will also identify critical information gaps that must be filled to reduce the uncertainty of streamflow requirements for aquatic ecosystems used by state and federal agencies to protect water resources. Further, the results of this project will include assessments of the likely impacts of climate change to the region’s aquatic resources.

The project objectives are as follows: To map out current and future levels of habitat connectivity in the South Atlantic region, from the standpoint of multiple groups of terrestrial wildlife species; 2. To prioritize key corridors and linkage areas based on their relative importance and centrality within the overall habitat network and their relative influence on the viability of target wildlife populations; 3. To publish data layers representing the outcomes from the first two objectives, in such a way as to significantly improve conservation decision-making across the South Atlantic LCC region

The USGS Southeast Ecological Science Center (SESC) Nonindigenous Aquatic Species (NAS) database provides records of sightings and capture data of non-native (introduced) aquatic species over the entire the United States (Benson 1999). For areas within the SALCC region, the NAS currently contains records dating back to 1885 for over 200 nonindigenous plant and animal species. This project seeks to utilize these data along with new GIS-based data on current and future (e.g. SLEUTH) landscape and climate parameters to develop models of invasive species introductions and dispersal across the SALCC region. Both multi- and single species models will be considered in these analyses. We will then utilize a formal decision-analytic...

Sea level rise (SLR) and disturbances from increased storm activity are expected to diminish coastal habitats available for sea turtle, seabird, shorebird, and beach mouse nesting by removing habitat as well as inundating nests during critical incubation periods. The goal of our proposed research is to evaluate past nesting patterns of fourteen coastal nesting species and predict future effects of sea level rise on nesting beaches along the South Atlantic Bight. Maps of coastal vulnerability to SLR combined with historical data sets of long-term and spatially extensive nesting habitat will lead to models that enhance our understanding of the complex environmental changes occurring from global climate change and...

The South Atlantic LCC is seeking technical assistance in the testing process for their newly chosen terrestrial natural resource indicators (https://www.fws.gov/science/catalog). For each ecosystem and the three indicators within each ecosystem, South Atlantic LCC staff and collaborators are seeking to answer the following: 1) How well does each indicator represent a variety of organisms and ecological attributes within the ecosystem and throughout a major portion of the LCC? What does it miss? 2) How well does combination of three indicators within each ecosystem represent a variety of organisms and ecological attributes within the ecosystem and throughout a major portion of the LCC? What do they miss? 3) How...
There are myriad barriers to aquatic connectivity beyond dams, with culverts at road crossings primary among them. UGA will lead the effort to develop a database of these non-dam blockages and model the likelihood that each is a barrier to fish movement, including mussel hosts. This process, described in more detail below, will result in a GIS point layer with numeric attributes that describe the likelihood that any given crossing is a blockage to fish passage. This data will be incorporated into the dam database to produce a database of all known and potential barriers in the region. This unified database will form the unit of analysis for the subsequent connectivity assessment in which each of the barriers will...

In 2012, the South Atlantic Landscape Conservation Cooperative (SALCC) began development of its process to select natural resource indicators and targets as specific landscape scale measures of success for natural resources. An indicator was defined by the SALCC as a metric designed to inform easily and quickly about the conditions of a system, where as a target is a numeric goal established for an indicator. Recommendations were made to the SALCC steering committee in March to recommend indicators for aquatic and terrestrial ecosystems. Recommendations were based on input from 235 experts in marine, freshwater and terrestrial resources in the SALCC geography and adjacent LCCs. Indicator recommendations were considered...

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...

A priority of the Southeast Climate Science Center (SECSC) is to support the planning and implementation of a Southeast Conservation Adaptation Strategy (SECAS). This project examined the decision making context, decision making process, and management planning associated with the restoration of open pine ecosystems in the Southeast. To better understand the planning practice associated with this system, we assessed the quality of 35 management plans from federal, state, and non-governmental agencies. We found that newer plans scored higher than older plans, suggesting agencies may be learning to develop better plans over time and indicating older plans should be prioritized for revision. Plans from federal and...

Marshes are a critical habitat for a diversity of fauna and the ecological functioning of the coast. Despite their renowned vulnerability, uncertainty of wetland responses to sea-level rise remains a pervasive concern in coastal science and management, particularly for coastal resource conservation and climate change adaptation. Inventorying and mapping marsh dynamics have emerged as high priorities for assessing regional vulnerability to sea-level rise, requiring synthesis of existing marsh habitat maps, improved methodology for their continual monitoring, and assessment of their vulnerability with modeling and analysis. Multispectral remote sensing (balloon-, airplane- and satellite-based), LiDAR, NWI wetland...

The objective is to create a hydrologic foundation for detailed assessment of human and climate impacts on stream and river flows, including the impacts of hydrologic alterations on aquatic habitats. A specific application will be to support implementation of ELOHA, the Ecological Limits of Hydrologic Alteration, a scientific framework for determining environmental flow needs for all rivers and streams throughout a very large region. During Year 1, we will model pre-development (unaltered) daily flows for 1960-2006 for every enhanced national hydrography dataset (NHDPLUSPlus) catchment within the SALCC. We will also model current condition daily flows over the same time period for at least 6 watersheds using available...
This request is in support of the Southeast Natural Resource Leaders Group (SENRLG) Landscape Conservation and Restoration Pilot Project. Phase I of the study was completed with support from UNC Asheville’s National Environmental Modeling and Analysis Center (NEMAC) in June 2011 after working closely with the SENRLG Pilot Project Team in October 2010. The first phase identified federal resources available for supporting ecological, cultural, and sociological resource protection across the Southeast within an adaptive framework for building resilience into the system to address risk climate change impacts on the landscape. To further define the co-benefits of leveraging resources in a synergistic manner on the landscape,...

Many ecosystem models, particularly those that are “mechanistic” (based on an understanding of processes), are over-parameterized (not identifiable). As a result, model parameters are selected (not estimated using an optimization technique), parametererror/covariance terms become extremely difficult to estimate, and Monte Carlo error propagation does not adequately capture the effect of all uncertain model terms. In those situations, techniques that evolved from Regional (Generalized) Sensitivity Analysis (RSA), such as Generalized Likelihood Uncertainty Estimation (GLUE), Bayes Monte Carlo, and Markov Chain Monte Carlo (MCMC), are preferred techniques for model error propagation. These techniques can be used to...
