Project Overview Many insect pollinator species in the southeastern US and the US Caribbean, including bees and butterflies, face increasing threats from climate change, but few have been assessed for their vulnerability to these threats. This leaves wildlife managers without crucial information for conservation planning. Researchers supported by this Southeast CASC project will work...

Project Overview Coastal marshes in the Gulf of America host diverse ecological communities and hold Native American cultural artifacts within shell mounds (middens). However, both are vulnerable to erosion and submergence due to rising sea levels and more frequent severe storms. Researchers supported by this Southeast CASC project will develop a risk-assessment tool to evaluate the...

The US Virgin Islands are vulnerable to sea level rise, intense storms, and unpredictable rainfall brought by climate change. These changes influence the health of freshwater streams (known as “ghuts”), sedimentation, erosion and water quality (“grit”), as well as aquatic communities and ecosystems (“gills”) that are unique to the islands and important for indigenous peoples’ heritage...

Project Overview Climate and economic stressors are causing large numbers of people to emigrate from Puerto Rico and the U.S. Virgin Islands, even while new development continues. To provide a tool to help managers and policymakers make informed decisions about development and conservation, researchers for this Southeast CASC-supported project will co-produce a land change model that can...

An invasive species is a species that is not native to a location and that rapidly grows and spreads in its new range, often damaging native plants and wildlife. At present, the southeastern USA harbors thousands of invasive plants and animals, which were introduced intentionally through the plant and pet trade or unintentionally through other forms of commercial trade. Many of these...

Project Overview Climate change and invasive fish species threaten the resilience and biodiversity of freshwater ecosystems in the Southeastern U.S., including the Everglades, which are vital to the Miccosukee Tribe of Indians of Florida. Researchers supported by this Southeast CASC project will model invasive fish distributions under changing climate conditions and refine the model...

Project Overview Climate change is expected to worsen the spread of invasive vines in the Southeast, where they disrupt ecosystems and damage human-built systems like agriculture and infrastructure. Researchers supported by this Southeast CASC project will combine species distribution models and remote sensing to improve predictions of vine spread by including often-overlooked biotic...

Project Overview Managers in the Southeast and US Caribbean face challenges accessing, interpreting, and using climate adaptation information, especially under tight decision-making timelines. Through this Southeast CASC project, researchers will co-produce a synthesis of regional climate adaptation science, identify information gaps, and improve access to actionable climate information...

The southeastern U.S. is home to many rare plant species, some at risk of extinction. A new national list has identified the top plant “Species of Greatest Conservation Need” (SGCN) across the region which can help southeastern states update their State Wildlife Action Plans (SWAPs) to include plants for the first time. In partnership with the Southeast Plant Conservation Alliance...

Nature-based solutions provide benefits to both nature and people, simultaneously addressing the issues of climate change and biodiversity loss. The Department of the Interior (DOI) manages more than 480 million acres of natural and working lands in the United States, presenting a significant opportunity to leverage nature-based solutions to contribute to greenhouse gas reduction targets...

Cherokee Peoples have had a sustained presence in the southern Appalachians over the past 12,000 years, with a peak population of about 250,000 people inhabiting approximately 32 million hectares across Georgia, Alabama, Tennessee, Kentucky, West Virginia, Virginia, and the Carolinas. Early contact with European settlers caused drastic population declines and land loss, due to disease...

Amphibians in the US Caribbean, like the well-known coquí frog, are particularly vulnerable to human-caused climate change. Coquí frogs are represented by 17 species across Puerto Rico and US Virgin Islands and include several mountainous and coastal species that are threatened by extreme heat and drying, loss of coastal freshwater marshes through saltwater intrusion, or both. Over the...
