Flora of Old Control Road Area, San Jacinto Mountains

Species Checklist
Notes on Some Species


Fig. 1. Topo map showing the location of the Old Control Road (Forest Service Road 5S06) that connects SR74 just east of Hemet to Idyllwild, as well as the even older Crawford Toll Road. The Flora of the Old Control Road area is divided here into three sections: the lower-elevation part below Halfway Spring; Halfway Spring itself; and the higher-elevation part above Halfway Spring.

The Old Control Road is now just a rough dirt road that connects SR74 with Idyllwild that few people drive, but it has an illustrious past as the first route between Hemet and Idyllwild. The following history is summarized from the book The San Jacintos, by John W. Robinson and Bruce D. Risher, pp. 145-147.

Joseph Crawford opened his toll road in 1876 which took a very steep route up to Idyllwild, with grades up to 30%. Tourists used the road to go from Hemet to Idyllwild, and loggers used the road to bring wood from Idyllwild to Hemet.

In 1891 the Hemet Land and Water Company built a road in the San Jacinto River canyon bottom to build Hemet Dam. That road, called the Mayberry Road for Edward Mayberry, the person who planned and directed the project, went up to Keen Camp Summit and down into Garner Valley. In 1900 a steep lateral road was built from today's McCall Park to Chalk Hill in Strawberry Valley.

Riverside County built the current Old Control Road in 1908 and 1909, using and improving the lower portion of the Crawford Road and then adding a new gentler alignment in the upper portion that contoured around the steep hillside. The new portion went to Halfway Spring and the north side of Chimney Flats. The new portion rejoined the Crawford Road on the east side of Chimney Flats.

For 20 years, this Old Control Road was the main access to Idyllwild until the current version of SR74 was opened in 1929.

The current version of the Old Control Road is great for botanists, who can easily walk along the road and enjoy the plants and the views, without the high-speed traffic encountered on SR74. Botanists should still be alert for occasional bicyclist and 4 WD traffic on the weekends.

The Old Control Road is 7.9 miles from SR74 to SR243, from an elevation of 2280 feet at its bottom to 5230 feet at its top. Since its upper section is part of the Strawberry Valley Flora, the checklist present here is for the lower 4.9 miles, ending at the upper end of Chimney Flats at 4700 feet, where the road makes a turn to the northeast to head to Alvin Meadows.

The flora presented here has been compiled from one survey on foot on 8 May 2017 by Tom Chester and Nancy Accola, from mile 1.35 to mile 3.00, which is just above Halfway Spring at mile 2.9, as well as vouchers. Most vouchers came from a survey from Scott D. White and Justin M. Wood on 22 May 2009, with 37 vouchers (including duplicates), and from I.J. Condit on 24 June 1910, 32 vouchers (including duplicates). A few random additional species came from a car trip down the entire road by Tom Chester and Nancy Accola on 14 June 2016, and from a brief car visit on 28 May 2014 to the section of the road just above Chimney Flats.

Species Checklist

Basic information about the checklist presentation and links:

An asterisk before the Common Name indicates a non-native taxon.

The three columns under the header #Plants give a minimum estimate of the number of plants we saw, up to a maximum of 99 plants, except as given below. An x in any column indicates a species that was seen by us, but whose abundance was not recorded.

The column with header B gives the number of plants seen Below Halfway Spring; the column with header HS gives the number of plants for species seen only at Halfway Spring; and the column with header A gives the number of plants seen Above Halfway Spring.

A V in any column indicates a species that was vouchered, but not yet seen by us.

A ~V in any column indicates our best guess as to which section a voucher was taken, for vouchers without that information given. The vouchers by White and Wood explicitly give the section, but the vouchers by Condit just say "road to Strawberry Valley" or "road to Idyllwild". For the Condit vouchers of species not seen by us or vouchered by White and Wood, we have used our best judgment as to whether each of those vouchers was taken from above or below Halfway Spring, based on the usual elevation range for those taxa.

Notes on Some Species

Eriogonum fasciculatum. Both variety foliolosum and variety polifolium are found on this road, sometimes almost side by side. We did not count the number of plants for each variety separately, and just report the numbers for the species, with an x in the column B for each variety, indicating they both exist here.
