    Longfin smelt (Spirinchus thaleichthys) are relatively small (10-20 cm) anadromous fish with characteristically long pectoral fins that can be found in middle or deeper parts of the water column of estuaries and bays from California to Alaska. Longfin smelt were listed throughout their range in California as Threatened under the California Endangered Species Act in 2009. Recently, due to ongoing threats from altered hydrology, nonnative species, and effects of climate change, the U.S. Fish and Wildlife Service (USFWS) ruled that the San Francisco Bay-Delta distinct population segment (DPS) of the longfin smelt is Federally Endangered (effective 29 August 2024).

    Because different populations in California now have different legal status, CNDDB has added a new species record for the Bay-Delta DPS and split our Element Occurrence records based on these populations. The following are our two species records representing this taxon along with their general distribution based on the USFWS’s recent descriptions and map figures:

    • Longfin smelt (Spirinchus thaleichthys)
      • State Threatened
      • Coastal estuaries north of the Russian River (primarily Humboldt Bay) and south of Pillar Point, Half Moon Bay.
    • Longfin smelt - San Francisco Bay-Delta DPS (Spirinchus thaleichthys pop. 2)
      • State Threatened
      • Federally Endangered
      • Gulf of the Farallones from Russian River to Pillar Point, Half Moon Bay, and salt and freshwater habitats upstream of the Golden Gate including the San Francisco Bay, Sacramento - San Joaquin River Delta, and their tributaries where found.

    The California Department of Fish and Wildlife (CDFW) has initiated a five-year species review (Species Review) for the state endangered Indian Knob mountainbalm (Eriodictyon altissimum) to inform the California Fish and Game Commission's decision on whether to retain or change the status of the species under the California Endangered Species Act (CESA). As part of this process, the CNDDB would like to encourage anyone who has observed Indian Knob mountainbalm to submit their findings to us. People who have questions or comments about the review process should email the Native Plant Program at NativePlants@wildlife.ca.gov. The deadline to submit data and comments is September 9, 2024, to allow us sufficient time for evaluation.

    Indian Knob mountainbalm is a shrub known from only six populations in San Luis Obispo County, California. Four of those populations are located in the Los Osos area of San Luis Obispo County and two populations are located just south of the City of San Luis Obispo in San Luis Obispo County. This species was originally listed as endangered in 1979 under the Native Plant Protection Act and then afforded protection under CESA in 1984 when endangered plants became a part of CESA (Fish & G. Code, §§ 1900 et seq., 2050 et seq.).

    The purpose of a Species Review is to use the best scientific information available to determine if the conditions that led to the original species listing are still present or have changed since listing, and to recommend retaining or changing the status of the species (Fish & G. Code, §§ 2072.3 & 2077). Process information, along with recently completed reviews, are available on our web page for Five-Year Reviews of Rare, Threatened and Endangered Species. Take of this species is prohibited without an appropriate permit for scientific, educational or management purposes. For more information on permitting, visit our CESA permits web page.

    We need your help in better understanding the endangered status of Indian Knob mountainbalm. If you have ever found the species in the wild, submit your findings to us through our Online Field Survey Form.
