California Botanical Society

California Botanical Society The California Botanical Society was founded by Willis Linn Jepson in 1913 and serves a major role in advancing Western American botany.

The Society welcomes membership by all interested individuals worldwide and encourages members to submit manuscripts on original research to the Editor of Madroño for consideration as publications in the journal. Articles and notes (in English or Spanish) on ecology, systematics, floristics, conservation biology, and other areas of organismal botany are routinely published in Madroño, in addition

to noteworthy collections. The Society sponsors annual or biennial graduate student meetings and an annual banquet at various locations in California.

If you are interested in floristic studies, I recommend watching our recently uploaded talk by Nina House from the Jepson Herbarium team! During this talk, she discussed her research conducting floristic surveys in the Sierra Nevadas, as well as the importance of Herbaria, and much more!

Lithophragma maximum is a narrow endemic, restricted to San Clemente Island. Classified as Endangered under both the California Endangered Species Act and the Federal Endangered Species Act. Concerns remain about the taxon’s ability to adapt to warming and drying climate trends, as previous greenhouse studies show that a cold snap is required for successful germination. In this study by Kristen Hasentsab-Lehman et al, they assess the genetic diversity of the species across its range using ddRADseq. The results show that direct conservation intervention and careful genetic management of in-situ populations are necessary to achieve recovery goals for L. maximum

Disturbances can shape plant communities long after the initial event. Although the persistence and scale of these effects remain complex, many instances can conflict with restoration efforts. In a study, Annie Meeder et al examined Santa Cruz Island, California, as a compelling case study in the legacy effects of disturbances. Santa Cruz Island has been subject to a century of intensive grazing by non-native cattle, feral sheep, and rooting by feral pigs, followed by large-scale eradication and fire management interventions.

In their study, they resurveyed 40 permanent grassland plots in southwestern Santa Cruz Island that were previously sampled in the 1990s, during the height of pig activity. Their results suggest that while pig disturbance had acute short-term effects, the most enduring legacy may be the non-native-dominated communities that became established in the late 19th century.
