Mountain meadows in California are unique ecosystems that provide critical hydrological functions such as water storage, filtration, and release. These meadows are also important habitat for a variety of wildlife and plants. Historically, many of these meadows were used for agriculture and grazing, which often resulted in significant degradation. However, efforts are now underway to restore these important ecosystems.

The hydrology of mountain meadows is complex, with specific surface flow and snowpack providers contributing to the water supply. Snowpack provides a large portion of the water in the spring and summer, while specific surface flow occurs when groundwater discharges onto the surface, resulting in the formation of a stream.

Agricultural uses of mountain meadows have decreased in recent years, but some grazing still occurs. Recreational uses include hiking, fishing, and wildlife viewing. Overall, mountain meadows are important ecosystems that provide essential hydrological functions and habitat for wildlife.
