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,...
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...

The Virginia Department of Conservation and Recreation – Natural Heritage Program (DCRDNH) and the Florida Natural Areas Inventory (FNAI) at Florida State University (collectively, Project Partners) were funded by the South Atlantic Landscape Conservation Cooperative (SALCC) in April 2015 to develop ten species distribution models (SDM) of priority at-risk andrange-restricted species (Ambystoma cingulatum, Echinacea laevigata, Heterodon simus, Lindera melissifolia, Lythrum curtissii, Notophthalmus perstriatus, Phemeranthus piedmontanus, Rhus michauxii, and Schwalbea americana) for the purposes of incorporating the models and supporting information on the conservation and management needs of the species into the...

Managers and scientists are working together in a new project to understand and optimally manage conservation lands along the Atlanta and Mississippi Flyways to support continental populations of waterbirds. It will advance the development of an integrated waterbird monitoring and management program to inform decision-makers and resource managers in an adaptive management context, resulting in improved resource contributions toward waterfowl, shorebirds, and long-legged waders. This project uses adaptive management and modeling tin an innovative way that incorporates their management expertise as well as new conservation planning and modeling tools. We are focusing on wetland-dependent migratory birds that use the...

The South Atlantic LCC is committed to an iterative approach for both refining the information that drives the Conservation Blueprint as well as the utility of the Blueprint to inform conservation decisions. The South Atlantic LCC wishes to provide additional funding to the Cooperative Ecosystem Studies Unit’s existing contract to build on prior deliverables and expand research involving science delivery needs of its cooperative members and communicating science delivery products.Project Objectives 2017-2018To support the South Atlantic LCC in the roles of extension and research by working with cooperative members.1.

This pilot project will assist the South Atlantic Landscape Conservation Cooperative (SALCC) identify issues dealing with the integration of natural and cultural resource sustainability and recommend optimal strategies for solving impacts associated with landscape stressors like climate change, invasive species, water scarcity, and habitat fragmentation. The goal of this project will be to provide the SALCC an action plan for use in future efforts to integrate optimal sustainability strategies for natural and cultural resources. The project will identify areas of overlap and disjunction between optimal methods of natural resource sustainability and cultural resource sustainability. Within this framework, cultural...

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 South Atlantic LCC is seeking technical assistance in evaluating the past, current, and future condition of the ecological systems of the South Atlantic. The South Atlantic LCC is currently doing a “State of the South Atlantic” assessment to evaluate the past, current, and future condition of 9 broad ecosystem types. This procurement focuses on the approximately 71 ecological systems that exist completely or partially within the South Atlantic and are nested within the 9 South Atlantic LCC ecosystem types. South Atlantic LCC staff and collaborators are seeking technical assistance in evaluating the past, current, and future condition of the ecological systems of the South Atlantic and a concise report documenting...

The specific objectives of this project are to a) assemble existing mussel, water quality, and landscape level (e.g., GIS) data bases; b) conduct expert interviews, targeted mussel surveys, and habitat assessments; c) develop an integrated model to predict species occupancy and to identify specific stream segments for conservation, restoration, and augmentation; and d) validate and refine the model for applicability to other species and geographic regions. Results of this project will be used to develop scientifically defensible estimates of the stream network needing conservation to support mussel recovery; identify specific factors limiting recovery of federally-listed mussels in a watershed manner; enable predictions...

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...

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...
