Indicators

NatureCheck indicators are wildlife and plant communities that provide essential ecological function or habitat which can be measured to assess the health of our East Bay ecosystems.

Indicators are akin to human vital signs, such as blood pressure and pulse: easily measured and strongly correlated with an overall condition, sensitive to stressors, and early warnings of potential problems.
