Introduction

The Punta Mesa Trail begins at the Adobe Loop Trail and ends at a four-way junction with Monument Hill, Fault and Waterline Roads. To get to the beginning of this guide, follow the directions to get to the Adobe Loop Trail and take the Adobe Loop Trail 0.4 miles to the beginning of the Punta Mesa Trail.
The Punta Mesa Trail is 1.94 miles one-way, with 200 feet of elevation gain and loss.
This guide includes the portion of Monument Hill Road between Fault Road and the Vista Grande Trail, making the total length of this guide 2.13 miles, with 300 feet of elevation gain.
One unusual aspect of this trail is that it is almost entirely in the Bedford Canyon Formation, and shows numerous exposures of it. The rest of the trails at the Santa Rosa Plateau Ecological Reserve are either on the Santa Rosa Basalt, or show exposures primarily of the Woodson Mountain Granodiorite.
The trail also offers a good view of two 8 million year old stream valleys that were filled by the Santa Rosa Basalt when the basalt flowed over the landscape.

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. There were 93 trails in our database when this histogram was made; 16 of those trails, including this one, are at the Santa Rosa Plateau Ecological Reserve. A number of "1" means the taxon has only been found only on this list, among all the trails in our database; numbers of "16" or smaller may indicate taxa found only in this area.

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.

Only the first 0.34 miles was surveyed on 11/6/04. The fieldwork on 2/2/05 was minimal, since that was mostly a hiking trip. Only the first 0.02 miles was surveyed on 3/10/05, but note how many new taxa were added from annual and perennial herbs! Only the first 0.72 miles was surveyed on 4/7/05.

Comments On Specific Species

Calochortus splendens. A definite id was made at mile 0.52, which is listed separately but not numbered. It is likely, but not 100% certain, that the plant at mile 0.25 is this id.
Opuntia vaseyi. The first occurrence at mile 0.11 is a young plant; a definite identification was made at mile 0.59.
Foeniculum vulgare. We are trying to remove the infestation here, so we hope you don't see any of this species here! If you do, please yank them out.
Isocoma menziesii. In our experience, the subspecies are not separable in Southern California. See Comments on the Jepson Manual and A Flora of Southern California by Munz: Isocoma menziesii.
There is only a single plant on this trail, and it occurs almost right in the middle of the trail. Hence it frequently gets mowed down, making it pretty hard to spot.
Tragopogon dubius. The single plant that occurred here was weeded out.
Calystegia macrostegia ssp. arida. About half the plants at the SRP appear to be ssp. arida, with the other half split between sspp. "intermedia" and "tenuifolia". It has long troubled Tom to be finding three subspecies in the small area of the SRP. Worse, the classification of a given plant has changed with time, which was extremely puzzling.
These difficulties were resolved when Tom found clear evidence that subspecies "intermedia" and "tenuifolia" are bogus. Hence we assign all the SRP plants to ssp. arida.
