Number of Unique Taxa On This Trail

Histogram not updated from latest field work.

The following histogram gives the number of trails in our database that contain each taxon on this trail (not including the taxa seen only off-trail given at the end of the guide). We had 109 trails in our database when this histogram was made; 10 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 "10" or smaller may indicate taxa found only in this area of San Jacinto Mountain.

We found 2 additional species not in the above table, since they have not been fully 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.

The fieldwork on 8/7/07 was only to mile 1.18.

We thank Eric Baecht, Gabi and Cliff McLean for help with the fieldwork on 8/12/07, and Dave Stith, Anne Kelly and Aaron Fellows for help with the fieldwork on 7/3/08. Mountain goats Anne and Aaron found the Ranunculus and Oxyria in the Snow Canyon snowmelt gully.

Side: Side of trail on which the first occurrence is found: left, right, both, or center

#: On-Trail species are numbered in order of first occurrence on trail (touchable without leaving the trail). Off-trail species are in parentheses.

id?: Species without an entry in this column are positively identified. "?" means we are just guessing the identification; "sp" means the genera is probably known, but the species name is uncertain; "~" means we have 95% confidence that this is the determination, but have not yet positively identified it; "ssp" means the subspecies or variety needs to be determined.

#here gives the minimum number of on-trail plants of this species on this trail, with the number of locations on this trail following the /, using maximum values of 99/9. 1/1 means a single plant in a single location; 20/9 means 20 plants occurring in at least 9 locations, etc.
