What We Monitor

The Sierra Nevada Network conducts long-term monitoring to track changes in a subset park natural resources and processes, called "vital signs." Monitoring these selected vital signs helps us to understand the overall health or condition of bird populations, high-elevation forests, lakes, river hydrology, and wetlands. Monitoring also helps us track variability in climate, a driver of change in park ecosystems.

Knowing if and how key resources or processes are changing can help park managers develop effective approaches to management, restoration, and mitigation. To monitor park vital signs, the Sierra Nevada Network has developed and implemented the long-term monitoring projects shown below.
