Introduction

This is the guide to the portion of the Cedar Spring Trail from the Pacific Crest Trail (PCT) to Cedar Spring itself. For an introduction to this trail, direction to the trailhead, and the length and elevation gain of this trail, see Cedar Spring Trail: Trailhead to PCT.
This guide is the result of a single trip on 28 October 2008 and hence is especially incomplete for annuals and some perennials. The definitive determination of many species needs to be checked, since the initial survey concentrated just on finding the species here.

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 131 trails in our database when this histogram was made; 4 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 "4" or smaller may indicate taxa found only in this area of San Jacinto Mountain.
