Plant Guide to Tahquitz Valley Loop via PCT, San Jacinto Mountains

Plant Guide to Tahquitz Valley Loop via PCT, San Jacinto Mountains

This is a working list, about which we make no guarantees at all until we officially release it. Use at your own risk!

Introduction and Explanation of Plant Trail Guides
This loop trail begins and ends at Saddle Junction, at the top of the Devils Slide Trail. At Saddle Junction, take the rightmost trail, the PCT, to Chinquapin Flat. Many hikers will want to take the short side trip to Tahquitz Peak from there, using the South Ridge Trail. This guide doesn't take that excursion; it continues on the PCT to the Little Tahquitz Trail, and then takes the latter trail through Little Tahquitz Valley and Tahquitz Meadow. The loop ends using the Caramba Trail to return to Saddle Junction.

Number of Unique Taxa On This Trail

The following histogram gives the number of trails in our database that contain each taxon on this trail. We had 93 trails in our database when this histogram was made; 5 of those trails, including this one, are in this area of San Jacinto Mountain. A number of "1" means the taxon has only been found on this trail among the trails in our database; numbers of "5" or smaller may indicate taxa found only in this area of San Jacinto Mountain.

We found 3 additional species not in the above table, since they have not been identified yet. The unidentified ones are marked with ? or sp 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.

There are two entries for 7/26/06, which was the first time this guide was extended past Chinquapin Flat. The first entry gives the numbers up to Chinquapin Flat for comparison with previous entries; the second entry is for the complete loop.
We thank Joan Zimmerman for helping with the 10/5/04 fieldwork, and for finding the Hulsea vestita ssp. callicarpha then. Michael Charters found the off-trail plain mariposa lily, Calochortus invenustus, on 6/29/06. The fieldwork on 7/10/06 was only for the first 0.10 mile.
We thank Jay Sullivan for helping with the 7/26/06 fieldwork.
