Status Codes:

Endangered: Listed as Endangered by the State of California or the Federal Government

Threatened: Listed as Threatened by the State of California or the Federal Government

Depleted: Depleted according the Marine Mammal Protection Act (special status)

Category 1: Candidate for listing by the U. S. Fish and Wildlife Service (sufficient biological information available to support a proposal to list taxa as Endangered or Threatened)

Category 2: Candidate for listing by the U. S. Fish and Wildlife Service (existing information indicates taxa may warrant listing, butsubstantial biological information necessary to support a proposed rule is lacking)

CSC: California Department of Fish and Game "Species of Special Concern"

SCT: California Candidate for listing as Threatened

FSS: Federal Bureau of Land Management or U.S. Forest Service Sensitive Species

SPL: Species proposed for listing

* Taxa listed with an asterisk fall into one or more of the following categories:

1. Taxa that are biologically rare, very restricted in distribution, declining throughout their range, or at a critical stage in their life cycle when residing in California.

2. Populations(s) in California that may be peripheral to the major portion of a taxon's range, but which are threatened with extirpation within California.

3. Taxa closely associated with a habitat that is declining in California (e.g., wetlands, riparian, old growth forest).

+ The coast wide status of all Chinook runs is currently being reviewed for the California, Oregon and Washington coasts. Within the MBNMS boundaries the Spring, late Fall and San Joaquin Fall runs are considered to have depressed populations.

CNPS: California Native Plant Society CNPS Codes:
1B: Rare, threatened or endangered in California and elsewhere
