The Sierra Nevada is one of the most significant natural and biologically diverse regions in the world.
Sierra Nevada Region, by the numbers:
- Constitutes about 25 percent of California’s land area, or 25 million acres.
- Is California’s principal watershed, supplying over 60 percent of the developed water supply.
- Stores nearly half of California’s total forest carbon, which helps mitigate climate change.
- Sustains an extensive tourism/recreation industry—over 50 million recreation visit days a year.
- Supports 212 communities with more than 600,000 residents.
- Houses 60 percent of California’s total animal species (vertebrates)—572 distinct species. Over one-third are listed as rare, threatened, or endangered by the Department of Fish and Wildlife.

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.
The lack of wood and biomass processing infrastructure in the Sierra Nevada is a significant impediment to forest restoration efforts.
|Abandoned Mine Lands
California’s Gold Rush spawned population growth, new technology, and wealth in the state. However, legacy abandoned mine lands (AML) continue to impact our water bodies and us.
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.
