Ecohydroclimatology is an emerging frontier in earth system science that focuses on the interactions of water, climate, and ecosystems, as well as their implications to society.  As anthropogenic climate change continues to warm Earth’s surface, the quantity of water stored as snow in our mountain reservoirs is decreasing rapidly.  At the same time, disturbance events such as wildfire, drought, and forest harvest are increasing.  To promote a more resilient future in natural resource management, it is critical we understand the mechanisms, processes, and interactions between water, climate, ecosystems, and society.
