Project Overview Minnesota’s forests are being impacted by the effects of numerous climate related disturbances, such as invasive species, increased temperatures and flooding, and severe weather. While managers are working to ensure the longevity of these forests, they are facing a lack of information on how forests are responding to these effects and which strategies prove most...

Project Overview Wild Rice is an important piece of Indigenous culture for tribal communities in the Upper Midwest. However, given the high vulnerability of this aquatic plant to climate change, tribal communities have seen a significant decline of Wild Rice in the past century. Despite the expansion of monitoring and restoration efforts, intensified agriculture has also contributed to...

Project Overview Increasing severe drought events occurring across the Colorado Plateau can harm vegetation and create drier and more flammable fuel for wildfire. Researchers supported by this Southwest CASC project will analyze drought indices and satellite data to show how quickly after drought begins that different types of vegetation across the region show signs of health declines...

Project Overview The sandbar willow of the Klamath River is used within the Karuk Tribe’s ongoing cultural practices of basketweaving. The willow has been threatened by intensifying fire and dams, but restoration and the recent historical dam removals provide an opportunity to increase the quantity, quality, and access to this important resource. Researchers supported by this Southwest...

Rangelands in California face significant challenges from climate change, wildfires, and invasive species, threatening their productivity and the benefits they provide to local communities. Researchers supported by this Southwest CASC project will develop a management framework for restoring climate-resilient rangelands in California by examining interactions between fire, grazing, and...

Recent catastrophic droughts and wildfires have killed almost 20% of mature giant sequoia trees across California, and it is uncertain whether natural seedling regeneration will be enough to restore these forests, especially in severely burned areas. Researchers supported by this Southwest CASC project will assess whether soil conditions, such as moisture and soil microbial communities...

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...

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 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 Palmyra Atoll National Wildlife Refuge (NWR) is a critical nesting site for seabirds in the central Pacific Ocean, with ecosystems that are regularly impacted by the El Niño Southern Oscillation (ENSO). Researchers supported by this Pacific Islands CASC project aim to understand how past ENSO-driven climate variability and human activities have affected vegetation and...

Project Overview The James Campbell National Wildlife Refuge in Hawai’i provides important wetland habitats for four species of endangered waterbirds. However, due to invasive species and climate change impacts, these habitats are becoming unsuitable for the fledging and longevity of these birds. Researchers supported by this Pacific Islands CASC project will examine the effectiveness of...

Project Overview Atolls in the tropical Pacific and Indian Oceans are experiencing significant changes to their landscapes and biodiversity due to climate change. Researchers supported by this Pacific Islands CASC will use historical data to study a 50+ year window of change in both islet size and the occurrence of lizard species. This work will better inform lizard distribution in light...
