A year ago in October of 2021, we posted about the legal status of bumble bees in California. Four of these bumble bees (B. franklini, B. crotchii, B. occidentalis, B. suckleyi) were petitioned for listing as endangered species under the California Endangered Species Act (CESA) in 2018. The California Fish and Game Commission determined that listing all four species as endangered “may be warranted” in June 2019, and the species advanced to candidacy. The Commission’s determination was challenged in court soon after, and candidacy or related protections were stayed during much of the ensuing litigation. A California court of appeal ultimately upheld the Commission’s determination, and the state Supreme Court declined to review the case. Candidacy was reinstated for all four bumble bee species on September 30, 2022. As candidate species, they receive the same legal protection afforded to endangered or threatened species (Fish & G. Code, §§ 2074.2 & 2085).

Both the Suckley’s and western bumble bees have been petitioned for federal listing and received positive 90-day findings. The species status assessment for western bumble bee is scheduled to be released in fiscal year 2024, and Suckley’s in fiscal year 2025.

The California Natural Diversity Database (CNDDB) tracks an additional two species of bumble bee considered species of greatest conservation need. This table includes the current status of all bumble bees tracked by the CNDDB:

Common Name Scientific Name State
State Rank
Other Status
Franklin's bumble bee B. franklini Candidate Endangered S1 IUCN Critical
Crotch bumble bee B. crotchii Candidate None S1S2 IUCN Endangered
western bumble bee B. occidentalis Candidate None S1 IUCN Vulnerable
Suckley's cuckoo
bumble bee
B. suckleyi Candidate None S1 IUCN Critical
obscure bumble bee B. caliginosus None None S1S2 IUCN Vulnerable
Morrison bumble bee B. morrisoni None None S1S2 IUCN Vulnerable

The California Department of Fish and Wildlife (CDFW) will be conducting a status review for the Inyo rock daisy (Perityle inyoensis) to inform the California Fish and Game Commission's decision on whether to list the species under the California Endangered Species Act (CESA). More details about the listing proposal and CDFW's request for public comments may be found in our CDFW newsletter. As part of this process, the CNDDB would like to encourage anyone who has observed Inyo rock daisy to submit their findings to us. People who have questions or comments about the review process should email our Native Plant Program. The deadline for both data submission and comments is December 1, 2022 to allow us sufficient time for evaluation.

Inyo rock daisy is a perennial subshrub in the sunflower family that is endemic to the high elevation areas (2,019-2,774 m/6,623-9,100 ft) of the southern Inyo Mountains of Inyo County, California. It is restricted to rock outcrops high in calcium carbonate in pinyon woodlands, Joshua tree woodlands, and sagebrush shrublands. Inyo rock daisy is known from 26 occurrences with a global population estimate in the low thousands. The main threat to Inyo rock daisy is modification and/or destruction of habitat due to mineral exploration and mining activities. Other potential threats include invasive plant species, climate change, small population size, and tourism related to the development of the Cerro Gordo ghost town.

As of September 2, 2022, the Inyo rock daisy is considered a candidate species under CESA and will therefore receive the same legal protection afforded to an endangered or threatened 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 status of the Inyo rock daisy. If you have ever found them in the wild, submit your findings to us through our Online Field Survey Form. Together, we can help the Fish and Game Commission make an informed decision on the listing proposal for the Inyo rock daisy.
