This is a loop hike beginning and ending at the signed Tovashal trailhead on Clinton Keith Road opposite the Visitor Center parking lot. The route takes the Torino Trail at mile 0.19 and follows it to its end at the junction with Sylvan Meadows Road. The route continues right on Sylvan Meadow Road to its junction with the Tovashal Trail, and then returns following the entire Tovashal Trail.

This loop hike is 2.4 miles round-trip, with 100 feet of elevation gain and loss.

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 90 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.

We found 1 additional species not in the above table, since it has not been fully 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.

The taxa found only on this trail, or on only a few trails, as of 4/26/05, are:

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.

Visit DateVisit ## taxa# "?"# "sp"# "~"# "ssp"

The fieldwork on 4/21/03 was only to the end of the Torino Trail. The numbers from 4/26/05 are given twice; first to that same end point, and then for the complete loop.

In addition, Kay Madore found two taxa new to the trail guide on 5/16/04, and one taxon new to the trail guide on 4/14/05. Dick Newell helped with the fieldwork on 1/25/06.

Comments On Specific Species

Sisymbrium irio. This was a brand-new weed for the Santa Rosa Plateau plant list, observed for the first time on 1/25/06 in the drainage from the La Cresta homes, in an area frequented by horses. It could have come from drainage from the La Cresta homes, or from horses, or both. The two specimens were weeded out and vouchered for the plant list.

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.

Castilleja densiflora. We do not feel the subspecies defined in the Jepson Manual are valid in Southern California. See note in the Vernal Pool Trail Plant Guide.
