CHANGES TO THE CNDDB SPECIAL VASCULAR PLANTS, BRYOPHYTES, AND LICHENS LIST October 2021 State of California Natural Resources Agency Department of Fish and Wildlife Biogeographic Data Branch California Natural Diversity Database (CNDDB) Recommended Citation: California Natural Diversity Database (CNDDB). October 2021. Changes to the CNDDB Special Vascular Plants, Bryophytes, and Lichens List. California Department of Fish and Wildlife. Sacramento, CA. Introduction This document summarizes changes made since 2006 to the plant taxa that the California Natural Diversity Database (CNDDB) tracks. The changes made each year are organized alphabetically by scientific name with brief notes as to whether the taxon was a new addition, rank change, deletion, or name change. The changes made since 2015 are broken down by month, but all previous changes are summarized by year. For additional information about the process for determining whether a plant species is tracked within the CNDDB, please see the document “The CNDDB and CNPS Rare Plant Status Review Process” on the CNDDB website.
