Loko iʻa, Hawaiian fishponds, are part of a rich history of indigenous aquaculture dating back to the 1400s. These unique ecosystems serve as key models of food sustainability across Hawaiʻi and the Pacific region. Hawaiʻi, among the most geographically isolated regions throughout the world, currently faces many challenges including environmental uncertainties, increasing urbanization, a growing p

Drought is a common consequence of climate variability in the south-central U.S., but they are expected to occur more often and become more intense with climate change. Natural resource managers can improve their planning efforts with advance warnings of impending drought. Using input from resource managers in the Chickasaw Nation, this research team previously created models that forecast drought

Increasing temperatures, decreasing rainfall, and more intense droughts and storms are threatening the health and wellbeing of ecosystems and communities across Hawai‘i and the Pacific Islands. Future rainfall and temperature projections provide some insight into future change, but uncertainty remains in when, where, and how impacts will manifest, presenting daunting challenges to natural resource

Federal and state agencies gather information; work with partners, stakeholders, and others; and then write planning documents that guide their natural and cultural resource management. To be useful, these planning documents must reflect current and anticipated conditions, and therefore must include information about climate change. However, there has been little research about what climate inform

Indigenous Nations are particularly vulnerable to the effects of climate change, due in part to their reliance on healthy ecosystems to provide culturally significant plants that are used for traditional foods, medicines, and materials. Further, many Indigenous communities have an under-resourced capacity for climate adaptation, resulting in significant environmental justice impacts that range fro

Large, hot, fast-moving wildfires are an increasing threat to communities and to the watersheds they rely upon. Forest managers work to reduce the risk from these fires using forest thinning and prescribed burning to reduce the amount of fuel in the forest. However, these activities are expensive, and it can be challenging to identify which acres of forest should be targeted with thinning and burn

Climate change threatens to damage historical sites and disrupt cultural practices in communities around the world, including the South-Central United States. Researchers are now paying greater attention to the impact of climate change on these cultural resources, but currently little guidance exists for decision makers who are interested in protecting them. Because communities value and interact

The amount of water flowing through a stream is an important driver of aquatic habitat, but scientists don’t often measure streamflow in the small stream networks that feed larger rivers. Monitoring smaller streams is especially important as climate change is causing them to (a) flood more often and more intensely, and (b) lose habitat as drought events and water temperatures increase. A better un

Small creeks and streams often dry out during the summer but still support many insects, fish, crayfish, and plants. Though intermittent streams are the most common type of flowing water across the globe, not much is known about which, how, why, or when streams dry or about how patterns of drying affect species in these habitats. More information about patterns of stream drying can help inform the

Human fossil fuel use and agricultural practices have increased atmospheric nitrogen deposits (e.g., through snow and rain) to mountain ecosystems. This, along with increasing measurable climate warming is affecting soil and water acidity and altering nutrient balances. In this project, North Central CASC-supported researchers will analyze decades of unexplored data, including surface water chemis

Hala is a much-loved plant by Native Hawaiian cultural practitioners and lauhala weavers, yet native coastal forests of hala are now considered rare in Hawaiʻi. Research on climate resilience indicates that hala has the potential to mitigate storm surges and act as a barrier between salt spray and crops growing near the shoreline. To provide opportunities for natural and cultural resource managers

In the North Central region, invasive species and climate change are intricately linked to changing fire regimes, and together, these drivers can have pronounced effects on ecosystems. When fires burn too hot or too frequently, they can prevent slow-growing native plants from regrowing. When this happens, the landscape can transform into a new type of ecosystem, such as a forest becoming a grassla
