Sierra Nevada forests provide a wealth of benefits to the state of California. However, extreme levels of tree mortality and an increase in large, damaging wildfires jeopardize these vital benefits and adversely impact California’s aggressive greenhouse gas reduction goals. These forests are gravely unhealthy and need our help to restore them.
In order to know whether the SNC is effectively carrying out its programs, and to track the human, resource, and environmental health and well-being of the Sierra Nevada, the SNC developed a set of system indicators in collaboration with subject experts and other organizations.
