The geographic information system (GIS) format spatial data set of vegetation for Moores Creek National Battlefield (MOCR) was created by the National Park Service (NPS) Southeast Coast Inventory and Monitoring Network (SECN). The MOCR covers an area of approximately 70 ha (173 acres). The map classification scheme used to create the vegetation data set is designed to represent local plant communities at the finest level possible using the National Vegetation Classification System. The vegetation data set was developed by interpreting aerial photographs collected in 2009 and extensive field surveys. Individuals who cooperated in this project include: the Southeast Regional Office of NatureServe and the NPS SECN....
During the winter of 2016 and the summer of 2018, the U.S. Geological Survey, Lower Mississippi-Gulf Water Science Center collected sediment cores for grain-size analysis in Mississippi and Arkansas. In a farm field adjacent to the Tallahatchie River near Money, Mississippi, 13 continuous sections of approximately 5-cm (2-in) diameter by approximately 1.5-m (5-ft) long sediment cores were extracted to better understand the sediment within the Mississippi River Valley alluvial aquifer. These data were used to support ongoing aquifer testing activities by the U.S. Department of Agriculture’s Agricultural Research Service. Lake Poinsett Dam is an earthen embankment dam located near Harrisburg, AR. In May of 2018, the...

In the northern Gulf of Mexico, mangrove forests have been expanding their northern range limits in parts of Texas, Louisiana, and north Florida since 1989. In response to warming winter temperatures, mangroves, which are dominant in warmer climates, are expected to continue migrating northward at the expense of salt marshes, which fare better in cooler climates. The ecological implications and timing of mangrove expansion is not well understood, and coastal wetland managers need information and tools that will enable them to identify and forecast the ecological impacts of this shift from salt marsh to mangrove-dominated coastal ecosystems. To address this need, researchers will host workshops and leverage existing...

Recreational angling in the U.S. represents a large group of people that catch and harvest fish for a variety of reasons, including for relaxation, adventure, social motivations, and consumption. Collectively, recreational anglers can exert pressures on both economies and fishery resources. Fish removals by anglers represent an important source of mortality data when trying to understand fish populations, and this information is even more important when the fishery is dominated by recreational and subsistence fishing. Currently, the magnitude of recreational angling is measured at local scales (for example, at a specific lake or stream) and the process to collect information from anglers varies widely by state...

The Southeastern U.S. spans broad ranges of physiographic settings and contains a wide variety of aquatic systems that provide habitat for hundreds of endemic aquatic species that pose interesting challenges and opportunities for managers of aquatic resources, particularly in the face of climate change. For example, the Southeast contains the southernmost populations of the eastern brook trout and other cold-water dependent species. Climate change is predicted to increase temperatures in the South and is likely to have a substantial effect on extant populations of cold-water biota. Thus, aquatic managers are tasked with developing strategies for preserving cold-water dependent biota, such as eastern brook trout,...

Assessing the impact of flow alteration on aquatic ecosystems has been identified as a critical area of research nationally and in the Southeast U.S. This project aimed to address the Ecohydrology Priority Science Need of the SE CSC FY2012 Annual Science Work Plan by developing an inventory and evaluation of current efforts and knowledge gaps in hydrological modeling for flow-­‐ecology science in global change impact studies across the Southeast. To accomplish this goal, we completed a thorough synthesis and evaluation of hydrologic modeling efforts in the Southeast region (including all states of the Southeastern Association of Fish and Wildlife Agencies (SEAFWA) including Alabama, Arkansas, Florida, Georgia, Kentucky,...

Coastal wetlands and the many beneficial services they provide (e.g., purifying water, buffering storm surge, providing habitat) are changing and disappearing as a result of sea-level rise brought about by climate change. Scientists have developed a wealth of information and resources to predict and aid decision-making related to sea-level rise. However, while some of these resources are easily accessible by coastal managers, many others require more expert knowledge to understand or utilize. The goal of this project was to collate science and models pertaining to the effects of sea-level on coastal wetlands into a format that would be accessible and useful to resource managers. Researchers conducted training sessions...

Policy-relevant flood risk modeling must capture interactions between physical and social processes to accurately project impacts from scenarios of sea level rise and inland flooding due to climate change. Here we simultaneously model urban growth, flood hazard change, and adaptive response using the FUTure Urban-Regional Environment Simulation (FUTURES) version 3 framework (Sanchez et al., 2023). FUTURES is an open source urban growth model designed to address the regional-scale ecological and environmental impacts of urbanization; it is one of the few land change models that explicitly captures the spatial structure of development in response to user-specified scenarios. We present probabilistic land change projections...

Frequent, low-intensity wildfires were once widespread across the Southeast US, which led to a reduction in unchecked vegetation growth that provided fuel for high-intensity fires. Both intentional and unintentional fire suppression and land-use changes have reduced many of these wildfires and the fire-adapted habitats in the region over time. This loss of frequent low-intensity wildfires on the landscape also increases the severity of wildfires due to fuel buildup and the encroachment of woody species. The remaining habitats and their native species (many of which are of conservation concern) are now almost completely dependent on prescribed burns for their persistence and survival. Successful application of fire...

The data contained in child items of this page were developed to support the Species Status Assessments conducted by the U.S. Fish & Wildlife Service and conservation planning for State, Federal, and non-government researchers, managers, landowners, and other partners for five focal herpetofauna species: gopher tortoise (Gopherus polyphemus), southern hognose snake (Heterodon simus), Florida pine snake (Pituophis melanoleucus mugitus), gopher frog (Lithobates capito), and striped newt (Notophthalmus perstriatus). These data were developed by the USGS Cooperative Fish & Wildlife Research Unit at the University of Georgia in collaboration with other partners. The three child items contain the following data: (1)...

National Wildlife Refuges (NWRs) along the East Coast of the United States protect habitat for a host of wildlife species, while also offering storm surge protection, improving water quality, supporting nurseries for commercially important fish and shellfish, and providing recreation opportunities for coastal communities. Yet in the last century, coastal ecosystems in the eastern U.S. have been severely altered by human development activities as well as sea-level rise and more frequent extreme events related to climate change. These influences threaten the ability of NWRs to protect our nation’s natural resources and to sustain their many beneficial services. Through this project, researchers are collaborating with...

For more information about how these data were developed, please see the final report. Expert opinion was used to define a resistance surface for each of the target animals, with higher resistance representing map units expected to be more difficult and more dangerous for species to move through. A set of nodes for each species, with node points indicating center locations for potential source populations for the species, are also defined. Note actual species population data to define the nodes is not used, as that data was often unavailable, and the focus is on the potential spread of the species across the SALCC region and not limited to models to known populations. Therefore, node locations were determined by...

Forest Retention Index classes for the southeastern United States at 2040 were processed using the Forest Retention Decision Tree and rendered on a 30-meter by 30-meter grid. The Forest Retention Index is used only for current forestland, identified using National Land Cover Database 2011. Many datasets were used as inputs for the Forest Retention Decision Tree, and they can be grouped into five broad categories: Protected, Tier 1 Priority, Tier 2 Priority, Threats to Forest Retention, and Socio-Economic Value of Forests. Protected datasets include Protected Areas Database-United States, National Conservation Easement Database, state-maintained databases, and private datasets volunteered by conservation partners....

The objective of this project is to map the supply of ecosystem services (where natural ecosystems have the capacity to provide a certain product or service that could be of use to people), use of those services (where people or other entities that use the product or service exist), and the condition of ecosystems providing these services over time. The resulting datasets were used to generate metrics for pilot ecosystem accounts for the southeast – part of natural capital accounts that assess ecosystems’ contributions to the economy in order to help governments better understand their reliance on natural systems and manage natural resources to ensure their benefits are sustained into the future. These data were...
Urban forests provide well-documented environmental and societal benefits valued at more than four billion dollars per year in the United States. As cities expand onto land once occupied by rural forests, urban trees take on an even more vital role in mitigating global climate change, conserving biodiversity, and protecting human health. Maintaining the health of trees is challenging in cities and in forests under climate change because of tree stress and pests. Unhealthy trees do not provide adequate ecosystem services or conservation value compared to healthy trees. In this work we found that exotic trees can remain healthy and maintain biodiversity of arthropods (e.g. spiders and insects) that is similar to native...

Many shorebirds and nearshore waterbirds are of conservation concern across the Gulf of Mexico due to stressors such as human disturbance, predation, and habitat loss and degradation. Conservation and protection of these birds is important for the functioning of healthy ecosystems and for maintaining biodiversity in North America. Consequently, resource managers along the gulf need decision-aiding tools that can efficiently help to answer important conservation questions for different species (e.g. which areas and how much area should be targeted by management actions to meet a particular species’ needs). To address this need, project researchers are developing statistical models that will help identify habitat...

To better understand the impacts of climate change, ecological studies are increasingly addressing the different effects of temperature on organisms and ecosystems. To measure air temperature at biologically relevant scales in the field, ecologists often use small, portable temperature sensors. These sensors must be shielded from solar radiation to provide accurate temperature measurements, but a review of 18 years of ecological literature indicated that shielding practices vary across studies (when the shielding is reported at all), and that ecologists often invent and construct ad-hoc radiation shields without testing their efficacy. The project researchers performed two field experiments to examine the accuracy...

The objective of this project was to provide scientists and the general public with access to information about the existence and operation of programs that monitor the effects of global change processes, such as climate and land use change, on important air, land, and water resources. This was a public service project intended to support both education and decision making by providing comprehensive “one stop” access to information about hundreds of monitoring programs in North Carolina and throughout the Southeast. This work aimed to provide additional development of the Global Change Monitoring Portal, which is currently in the pilot phase. Tasks included: • Compile, inventory, and map geographically, additional...

A hydrologic model was developed as part of the Southeast Regional Assessment Project using the Precipitation Runoff Modeling System (PRMS), a deterministic, distributed-parameter, process-based system that simulates the effects of precipitation, temperature, and land use on basin hydrology. Streamflow and other components of the hydrologic cycle simulated by PRMS were used to inform other types of simulations such as water-temperature, hydrodynamic, and ecosystem-dynamics simulations.
