California Heartbeat Initiative

Researching the effects of climate change on ecosystems to sustain California’s biodiversity.

Securing the future of our natural systems

The California Heartbeat Initiative (CHI) engages the diverse population of the Golden State to create an ecologically resilient future. The project applies research and monitoring, data analysis and communication, and training and mentoring to address climate warming, ecological change, and habitat loss.

The UC Natural Reserve System is the backbone of all CHI endeavors. With its diverse network of protected wildlands, the NRS is an ideal platform for research that seeks to secure a resilient future for humans and the natural world. CHI research benefits from longstanding NRS partnerships with major land management agencies, environmental organizations, and other universities. Read more
