Introduction

(more Intro to be supplied)
I have made a separate guide and key, primarily for beginning botanists, that just contains the shrubs and trees that have at least one specimen that is taller than ~1 m (3 feet) on this trail. The guide in this webpage has an overwhelming number of species on it, many of which are not of interest to people who just want to learn the plants with showy flowers.

Number of Unique Taxa On This Trail

The following histogram gives the number of trails in my database that contain each taxon on this trail. There were 90 trails in my database when this histogram was made; 16 of those trails, including this one, are at the Santa Rosa Plateau. A number of "1" means the taxon has only been found on this trail among the trails in my database; numbers of "16" or smaller may indicate taxa found only at the Santa Rosa Plateau.

I found 1 additional species not in the above table, since it has not been identified yet. The unidentified ones are marked with ?, sp, or ssp in the id? column in the guide, and have no entries in the #all column.
Fieldwork Dates and Summary of List Changes With Time

The following table gives the dates the trail was walked and taxa recorded. After each visit, the table gives the total number of taxa on the list and the breakdown of the taxa without positive identification. See Explanation of Plant Trail Guides to understand the symbols below.

I did not distinguish the sp and ~ classifications prior to 12/7/02 for this trail. The trip on 2/28/03 only covered the first 0.15 mile of the trail. On 3/19/03, I added 5 species found on the trail in 2001, but not seen in 2002 or so far in 2003. The trip on 12/8/03 was primarily to identify the Stephanomeria sp., and only the south loop was walked.
On 7/24/05, I moved 4 taxa to only being off-trail, deleted one taxon, and added 6 new taxa to the plant trail guide, giving the net gain of one taxon compared to 5/3/05.

Comments On Specific Species

Quercus agrifolia var. agrifolia. The first reported location for this species is a specimen planted in fall 2002. The second reported location is a natural specimen.
Poa annua. The identification is from plants at mile 0.68; it is possible the plants at the first location are P. infirma, which will be checked in the future.
Gnaphalium stramineum. The only specimen on the trail grew under the overhanging boulder, and germinated too late to bloom in 2005 for a definite identification.
Tragopogon dubius, Lamium amplexicaule. These non-native weeds are eliminated when seen, so I hope you do not see them. If you do, yank them out!
I thank Jane Strong for her considerable assistance with helping me to learn the plants of the Santa Rosa Plateau, and Kay Madore for her sharp eyes in helping me find interesting things on this trail. I thank Michael Charters for finding the first Xanthium and Trichostema for the list on 10/07/03.
