A summary of an environmental topic examined by the ENVS_560/L_Watershed_Systems class at CSUMB.


Special Status Species is a universal term used in the scientific community for species that are considered sufficiently rare that they require special consideration and/or protection and should be, or have been, listed as rare, threatened or endangered by the Federal and/or State governments.

Statutes Affecting the California Central Coast

Federal Acts

  • The National Environmental Policy Act (NEPA) was signed into law in 1970 and established the broad national framework for protecting the environment. NEPA's basic policy is to assure that all branches of government give proper consideration to the environment prior to undertaking any major Federal action that significantly affects the environment.[1]
  • The Endangered Species Act (ESA) was signed into law in 1973[2] and has been revised through time since its inception. One purpose of the ESA is to provide a means to preserve ecosystems used by threatened and endangered species by creating Critical Habitat[3]. These species are legally protected and California and Federal agencies are required to prevent further decline of listed species. Another goal of the ESA is to protect species by regulating their take.

California Acts

  • The California Endangered Species Act (CESA) was signed into law in 1970[4]. The act states that all native species of fishes, amphibians, reptiles, birds, mammals, invertebrates, and plants, and their habitats, threatened with extinction and those experiencing a significant decline which, if not halted, would lead to a threatened or endangered designation, will be protected or preserved. The California Department of Fish and Wildlife (CDFW) will work with all interested persons, agencies and organizations to protect and preserve these sensitive resources and their habitats.[4] The criteria for rare and endangered designations was formalized in the California Species Preservation Act.
  • The Native Plant Protection Act (NPPA) was enacted in 1977 and allows the Fish and Wildlife Commission to designate plants as rare or endangered. The NPPA directs the CDFW to carry out the intent to "preserve, protect and enhance rare and endangered plants in this State." The NPPA gave the California Fish and Wildlife Commission the power to designate native plants as endangered or rare, and to require permits for collecting, transporting, or selling such plants.[5]
  • Following the passage of the first Federal environmental protection statute, National Environmental Policy Act (NEPA), California State Assembly created a committee to study the possibility of supplementing the act through state law in 1970. The committee issued The Environmental Bill of Rights, a report that called for a California counterpart to NEPA that would require state and local agencies to identify the significant environmental impacts of their actions and to avoid or mitigate those impacts. Acting on the recommendations from the committee, the legislature passed and Governor Ronald Reagan signed the California Environmental Quality Act (CEQA) into law later the same year.[6] In 1983, the CEQA was amended to define and protect rare and endangered species. Rare species were reclassified as threatened, candidate species were introduced, and plants were included.[7]

Designations for Special Species

There are many, agency specific, special status designations (full list of designations) that have different legal implications. Listed species are those that have been listed under the Endangered Species Act (ESA) or California Endangered Species Act (CESA). There are other designations that do not carry the same legal weight, but serve to draw attention to at-risk species.

'Listed' Species (Federal and California)

Under the ESA designations, a species is listed under one of two categories, endangered or threatened, depending on status and the degree of threat. These species are legally protected and Federal agencies are required to prevent further decline of listed species. To help conserve genetic diversity, the ESA defines "species" broadly to include subspecies and distinct vertebrate populations.[8]

  • Endangered species are those which are in danger of extinction throughout all of a significant portion of its range.
  • Threatened species are those which are likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.

Similarly, under the CESA designations, a species is listed under one of two categories, endangered or threatened, depending on status and the degree of threat. While the State of California works in cooperation with Federal agencies[9], there are some species listed only under CESA designations. These species are legally protected and California agencies are required to prevent further decline of listed species. Also included on this list are animal "Candidates" for state listing.[10]

  • Endangered species are those which is in danger of extinction throughout all of a significant portion of its range
  • Threatened species are those which are likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.
  • Candidate species are those which are under evaluation to determine a designation[11]

Species of Special Concern (California)

The California Department of Fish and Wildlife (CDFW) maintain a list of Species of Special Concern (SSC), which encompasses species, subspecies, or distinct populations of animals native to California that currently satisfies one or more of the following criteria (not necessarily mutually exclusive):[12]

  • extirpated from the State or, in the case of birds, in its primary seasonal or breeding role
  • listed as threatened or endangered under the ESA but not under the CESA
  • meets the CESA definition of threatened or endangered but has not formally been listed under the CESA
  • experiencing, or formerly experienced, serious (noncyclical) population declines or range retractions (that have not been reversed) that, if continued or resumed, could qualify the species for threatened or endangered status under the CESA
  • has naturally small populations exhibiting high susceptibility to risk from any factor(s), that if realized, could lead to declines that would qualify the species for threatened or endangered status under the CESA.

'Watch Listed' Species (California)

The CDFW also maintains a Watch List for species that were previously SSC but no longer merit SSC status, or which do not meet SSC criteria but for which there is concern and a need for additional information to clarify status.[12]

Rare Species (California)

Plant species designated as “rare” under the California Native Plant Protection Act (NPPA).[13] With the 1984 modification of CESA, plants listed as endangered under the NPPA became endangered under CESA, however plants listed as rare under NPPA did not receive a designation under CESA.[4]

Although both laws allowed for the adoption of regulations allowing take of listed native plants, it is only under CESA that regulations were promulgated that allowed for take incidental to development projects. Since no such regulations were ever developed under the NPPA there is currently no mechanism for permitting take incidental to most development projects of the sixty-four plant species that remained listed as rare under the NPPA; agricultural and nursery operations are exempt under the NPPA as well as certain maintenance and other activities after proper notification. The current lack of a regulatory mechanism to permit take of NPPA rare species may create an impasse for many projects.[14]

Sensitive Species (Federal)

The United States Bureau of Land Management (BLM)[15] and U.S. Forest Service [16] maintain regional lists of Sensitive species. These species are present on land managed by those agencies which are at risk of becoming threatened or endangered. Once listed as sensitive, the agencies make land management decisions based on preventing those species from becoming listed. These conservation efforts are intra-agency initiatives. There is no external agency that enforces sensitive species policies. In the Forest Service, this activity is managed by the Threatened, Endangered, and Sensitive Species Program.[16]

Management Implications of Special Species Designations

Special status species on the Central Coast are managed by various Federal and State agencies. Special status species must be considered when planning and managing on federal, state, and private lands at various levels depending on the type of special status designation. Part of any environmental impact report is an assessment of the project's effect on special status species, as listed under the California Endangered Species Act (CESA). The detailed review process for development is outlined in the CEQA Overview.

'Listed' Species

Once a species is designated as endangered or threatened, Federal and State protective measures apply. These measures include:[18]

  • Protection from adverse effects of Federal activities
  • Restrictions on taking, transporting, or selling a species
  • Authority for agencies to develop and carry out recovery plans
  • Authority to purchase important habitat
  • Federal aid to California wildlife agencies
  • "Take" prohibitions

When listing a species as threatened or endangered, we also designate Critical Habitat for the species. This designation occurs about one year after the final listing, as long as it is prudent to do so and Critical Habitat is determined. Unlike the listing determination, economic impacts must be considered when designating Critical Habitat.

Species of Special Concern

The Species of Special Concern (SSC) designation does not confer legal protection, but often plays a role in land use decisions. SSC should be considered during the environmental review process. The CEQA requires State agencies, local governments, and special districts to evaluate and disclose impacts from "projects" in the State. Section 15380 of the CEQA Guidelines clearly indicates that species of special concern should be included in an analysis of project impacts if they can be shown to meet the criteria of sensitivity outlined therein. [12]

Large development projects often reject sites with documented Species of Special Concern to avoid complications should the species become later listed as endangered or threatened.[19]

'Watch Listed' Species

Metrics shall be applied to any Federally-listed taxon subsequently delisted to determine its new status as either a SSC or placement on a Watch List. The status of Watch List species is monitored regularly and should the degree of endangerment or rarity of a Watch List species change, its designation may be altered.[12]

Rare Species

The California Native Plant Society initially created five California Rare Plant Ranks (CRPR) in an effort to categorize degrees of concern[20]. This ranking was adopted by the California Department of Fish and Wildlife (CDFW) in their protocols for surveying and evaluating impacts to special status native plant populations and natural communities.[21] The CRPR are:

  • 1A: Plants Presumed Extirpated in California and Either Rare or Extinct Elsewhere
  • 1B: Plants Rare, Threatened, or Endangered in California and Elsewhere
  • 2A: Plants Presumed Extirpated in California, But Common Elsewhere
  • 2B: Plants Rare, Threatened, or Endangered in California, But More Common Elsewhere
  • 3: Plants About Which More Information is Needed - A Review List
  • 4: Plants of Limited Distribution - A Watch List

The CESA provides additional protections for species in the categories, including take prohibitions . As the responsible agency, CDFW has the authority to issue permits for the take of species listed under CESA, if the take is incidental to an otherwise lawful activity and the take would not jeopardize the continued existence of the species. Surveys are one of the preliminary steps to detect a listed or special status plant species or natural community that may be impacted significantly by a project.[21]

Incidental Take of Special Status Species

Normally, "take" of a threatened or endangered species, means to "harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct". Although, depending if the species is endangered or threatened, different take prohibitions may apply and incidental take can be permitted.[22][23]

While section 2080 of the Fish and Wildlife Code prohibits take of any species that the commission determines to be endangered or threatened, CESA allows for take incidental to otherwise lawful activity through section 2081(b) of the Fish and Wildlife Code. CESA emphasizes early consultation to avoid potential impacts to rare, endangered, and threatened species and to develop appropriate mitigation planning to offset project-caused losses of listed species populations and their essential habitats. For those state-listed species that are also listed under the ESA, CESA allows for consistent determinations with Federal incidental take statements under section 2080.1 of the Fish and Wildlife Code.[23]
