Projects by Region

Climate change threatens many functions of wetlands and habitat connectivity for migratory shorebirds who use wetlands across the Southern Great Plains. Researchers supported by this South Central CASC project will survey stakeholders in the region, project climate impacts on wetland-dependent birds, and create tools for conservation planning (e.g., ranking wetland importance to...

Project Overview: Extreme weather conditions may disrupt key life cycle events for pygmy rabbits, a species that relies on snow and underground burrows for protection from predators and extreme cold. Researchers supported by this Northwest CASC project will use models to understand how different snow patterns and subsurface temperatures will impact pygmy rabbit habitats. Project outcomes...

Project Overview Climate change is expected to change rainfall patterns on pacific islands like Hawaiʻi, but current global models lack the resolution to accurately predict local rainfall. Researchers supported by this Pacific Islands CASC project will use machine learning models and historical data to improve rainfall predictions and create detailed rainfall maps for Hawaiʻi that can be...

Declining water levels in the Great Salt Lake are part of a larger trend of decreasing water availability in the Southwestern U.S. that presents significant challenges for people, animals, and ecosystems. One challenge is that as some lakes dry, newly exposed sediment containing heavy metals can become toxic dust that blows into populated areas. Increased air pollution and other effects...

Forests in the Pacific Northwest support an extensive network of headwater streams and critical habitats for over 50 amphibian species, but face challenges from historical resource extraction, forest management, and climate change. Researchers supported by this Northwest CASC project will identify and map climate refugia to guide conservation strategies for at-risk amphibians, producing...

Project Overview Hawaiian honeycreepers face numerous threats related to sea level rise, increasing storm frequency, erosion and invasive species. These impacts can alter their habitat, making it unsuitable and detrimental to their already small populations. Researchers supported by this Pacific Islands CASC project will create additional populations of a Hawaiian honeycreeper species by

Project Overview Climate risks, including floods and heatwaves, impact communities in the Upper Mississippi River Basin, but gaps in data, policy, and collaboration in the region can hinder effective climate adaptation. Researchers supported by this Midwest CASC project will work with communities to identify flood-vulnerable areas, evaluate various nature-based solutions, and develop a...

Tallgrass prairies in the U.S. Southern Great Plains are threatened by the aggressive invasive plant Lespedeza cuneata, and climate change is expected to affect its spread in complex ways. Researchers supported by this South Central CASC project will use remote sensing, climate science, and ecological modelling to detect the plant, identify climate factors driving its spread, and...

Project Overview Collaboration among scientists, managers, and members of the public is critical for developing effective science products that respond to society’s most pressing challenges. To continue these collaborative efforts, USGS recognizes that participatory sciences can be a powerful tool in engaging diverse groups in the process of collecting and interpreting scientific...

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...
