The complex mountain and valley chains of the Southwest exert a strong influence on precipitation and wind patterns. Atmospheric rivers deliver some of the most extreme precipitation events to west-southwest-facing slopes of the mountains where strong gusty downslope winds can also spread wildfires. Climate change is making the southwest warmer and dryer resulting in more fire-prone...

The prairie grasslands of the Midwest and Great Plains provide important habitat for a wide variety of plants and animals, clean drinking water, and space for outdoor recreation and have experienced an over 99% loss of prairie grasslands due to a variety of factors including climate change. Land managers that are working to restore prairie grasslands would like to make them resilient to...

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...

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...

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...

Project Overview 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...

Recently intensifying drought conditions have caused increased stress to non-native tamarisk vegetation across riparian areas of the San Carlos Apache Tribe (hereafter Tribe) and the Upper Gila River watershed in Arizona and New Mexico. This also increases wildfire risk in the area, making the removal of tamarisk vegetation a primary restoration and climate adaptation objective for the...

Climate and land use change are affecting many aquatic species throughout Maryland, Pennsylvania, Virginia, and West Virginia. The objective of this project is to understand and plan for the changes in distribution of aquatic species considered “Regional Species of Greatest Conservation Need” (RSGCN) in the mid-Atlantic region. Working with state and federal partners, this project will...

Coastal wetland loss is a serious concern along the northern Gulf of America, especially in Texas and Louisiana where rates of wetland loss and relative sea-level rise are among the highest in the world, extreme storms are becoming more frequent, and flooding events are intensifying. Because coastal wetlands of the northern Gulf Coast provide numerous ecosystem services, including...

Project Overview Climate change has reduced the amount of water stored in snowpacks and altered avalanche risks in mountainous areas of western North America. Researchers supported by this North Central-CASC project will develop tools for predicting and managing future water resources and future avalanche patterns, particularly in areas of major transportation corridors and important...

The Midwest United States is facing wetter winters and springs and more variable precipitation in the summer and fall. Heavy floods and prolonged droughts are costly to agriculture, housing, transportation infrastructure, and recreational opportunities across the region. These extremes also stress the health of freshwater ecosystems that are important to the regional economy and quality...

Wildfire, drought, and insects are reshaping forests in the Western United States in a manner that is being exacerbated by warming temperatures. Disturbance events such as these can significantly alter the amount of land that is covered by forest in an area or region. Consequently, changes in forest cover from disturbance can impact water runoff conditions leading to dangerous flooding...
