Checklists of native and naturalized nonnative vascular plants are provided on this web page.   Checklists have been developed for a number of places and trails of Ventura County, California.   The checklist are based on the author's personal observations, with many of the observations supported by voucher specimens, which have been (or will be) deposited into the Herbarium at UCSB, or have been previously collected (vouchered) by other botanists.   The checklists are arranged alphabetically by placename.   Each checklist is a PDF formatted file, which requires Acrobat Reader (which can be downloaded free if you don't have it, just Google it).
