Plants of Southern California:
Botanical Trail Reports in Geographic Location Order

Unfortunately, it proved too much work to update this page as well as the Reports by Time, so this page is incomplete after 2005. See the Reports by Time for a complete list of reports.

The reports are organized by the geographic subdivisions of Southern California as given in the Jepson Manual, 1993, and are ordered roughly north to south and then west to east for areas roughly at the same latitude, both for the subdivisions and within each subdivision. The name of each trail is linked to its plant guide, if one is online, with the reports listed below.

Reports from Michael Charters or Jane Strong are identified by their name after the date; reports not so identified are from Tom Chester.
