Introduction

This trail guide begins at the southern trailhead of the Rock Ridge Trail, which is a trail that cuts near the center of the Boulder Loop Trail.
To reach the trailhead, begin at the parking lot at the main entrance to Daley Ranch, which is at the southernmost part of the property, just north of Lake Dixon at the top of La Honda Drive in Escondido. The only toilets nearby are at Lake Dixon, which have running water. It is free to walk through the Lake Dixon entrance to use them. A porta-potty is at the Ranch House at Daley Ranch, but is not along this route.
There are two options to get to the Rock Ridge Trail:

Take the Ranch House Trail, which is the paved main road of Daley Ranch, north for 0.7 miles to its intersection with the southern portion of the Boulder Loop Trail. Take the Boulder Loop Trail left for 0.4 miles to the signed Rock Ridge Trail southern trailhead. (Trail #1 to #3 to D on the Trail Map.)
Take the Ranch House Trail, which is the paved main road of Daley Ranch, north for 0.25 miles to the utility easement on the left. Turn left on the dirt road, and then immediately right on the easement that heads north for 0.4 miles to its intersection with the Boulder Loop Trail. (Near the intersection, bear left at the Y-junction to avoid the very steep section of the easement road.) This easement is not shown on the official Daley Ranch Trail map, but essentially cuts off the bend to the east of the Ranch House Trail. At the Boulder Loop Trail, turn left and continue for 0.2 miles to the signed Rock Ridge Trail southern trailhead.

Both of these options have about 400 feet of elevation gain to get to the Rock Ridge Trail southern trailhead.
The Rock Ridge Trail itself is 0.60 miles in length, with 170 feet of elevation gain and 50 feet of elevation loss. A roundtrip from the south entrance of Daley Ranch is 3.4 miles with ~650 feet of elevation gain and loss using the first option; or 2.9 miles roundtrip with ~650 feet of elevation gain and loss using the utility easement.
The Rock Ridge south trailhead GPS NAD27 coordinates, are (33.17461,-117.05797). GPS coordinates of the entire trail, with cumulative mileages along the trail, are here. Note that the elevations in that file are from my GPS receiver, not from the USGS map, and hence cannot be trusted to be accurate. However, a quick check reveals that they are generally within about 10 feet of the elevations from the USGS map. Elevations in the trail guide below are from the USGS map, and are accurate.

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 90 trails in our database when this histogram was made; 2 of those trails, including this one, are at Daley Ranch. A number of "1" means the taxon has only been found only on this list, among all the trails in our database; numbers of "2" may indicate taxa found only in this area.

We found 8 additional species not in the above table, since they have not been fully identified yet. The unidentified ones are marked with ?, sp or ssp in the id? column in the guide, and do not have a number given in the #all column.
The taxa that are unique to this trail, or to Daley Ranch, out of our 90 trails on 2 April 2005, are:

Latin Name Common Name Distribution
Centunculus minimus chaffweed This is found only in vernal pool and similar moist places below 950 m, and only in the SCo in Southern California, which is a disjunct from its main distribution in middle California.
Horkelia truncata Ramona horkelia This is a RARE taxon in the JM, found only from 400-1300 m in the PR and n Baja CA. It is also on the Hidden Spring Trail at Daley Ranch.
Juncus dubius dubius rush This is found only in the PR in Southern California, a disjunct from its main distribution from middle California to Oregon, including Death Valley. This appears to take the place of Juncus balticus, which seems to have a mostly complementary distribution to J. dubious. It is also on the Hidden Spring Trail at Daley Ranch.
Mimulus palmeri Palomar monkeyflower See note below.
Plagiobothrys collinus var. gracilis graceful popcorn flower Dry places; gen < 200 m; s SCo (near San Diego), ChI. We have var. fulvescens on one trail, at Mt. Hillyer in the San Gabriel Mountains.
Plantago elongata long-leaf plantain Saline and alkaline places, beaches, vernal pools; < 200 m; CA-FP (exc CaR, SN).
Psilocarphus tenellus var. tenellus slender woolly marbles Dry slopes on gen disturbed soil, rarely vernal pools; 10-2000 m; CA-FP.
Ophioglossum californicum California adder's-tongue This is an Uncommon taxon in the JM found from 60-300 m only in SCo in Southern California. Its distribution ranges from the SN to Mexico, but is only seen in the early spring during rainy periods.
Sagina decumbens ssp. occidentalis western pearlwort This is found in a variety of habitats below 2000 m, at SCo, ChI and PR in Southern California. Its distribution extends north to British Columbia.

In addition, this is the only trail in our database in which some specimens of scarlet pimpernel, Anagallis arvensis, have white flowers. See note below.
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 Date Visit # # taxa # "?" # "sp" # "~" # "ssp"

3/29/2005 3 138 2 5 7 2

^* The 4/12/03 fieldwork was part of a fast-paced hike with a botany class, and only noted a handful of species not found earlier on that trip on other trails. It is listed out of order in the above table since it was used only to supplement the list made on 7/31/04.
We thank an anonymous friend for her help with the fieldwork on 7/31/04.

Comments On Specific Species

Anagallis arvensis. Some of the plants here have white flowers, in addition to many with the usual salmon flowers. Both the JM and Munz mention that this species occasionally has blue flowers; neither mentions the possibility of occasional white flowers. However, many online pages mention white flowers.
Castilleja densiflora. The specimens here are nearly perfect var. densiflora except in one respect: the corolla is well-exserted, not included in the calyx. In particular, their calyx is 12-14 mm; the lower corolla lip is widened gradually, and the corolla pouches are longer than deep. An additional "problem" is that var. densiflora is not supposed to be south of Los Angeles County. (The San Diego County checklist only gives var. gracilis.)
The specimens at the Santa Rosa Plateau are even more troublesome to assign to just a single variety. They seem to have an intermixture of traits assigned to the two varieties.
As a result, we have decided to follow the example of Roberts et al in their Western Riverside County checklist, and Lathrop and Thorne in their Flora of the Santa Rosa Plateau, and simply call the specimens in Southern California by just the species name.
Calochortus sp.. The first specimen on the trail at mile 0.10 has a "V"-shaped leaf; the one at mile 0.29 has a "W"-shaped leaf. We have been told that these are the leaves of C. weedii and C. splendens (but don't remember which is which); we will be delighted to find out, when these plants bloom, if these species can be told apart by their leaves.
Mimulus palmeri. M. palmeri in the JM is the combination of plants from the Sierra Nevada and San Bernardino Mountains previously known under this name, with M. diffusus from the San Jacinto Mountains, Santa Ana mountains and northern Baja Mountains. The CNPS considers these two to be separate species, with M. diffusus a List 4 rare plant.
Carduus pycnocephalus. A single specimen appeared on the trail on 3/29/05, and we weeded it out.
Horkelia truncata. We found a large number of what appear to be seedlings of this species on the trail on 3/29/05; the first one is noted in the guide, as well as the first mature specimen. The mature specimen is not numbered as a new species.
Isocoma menziesii. The subspecies do not seem to be separable in Southern California. See Comments on the Jepson Manual and A Flora of Southern California by Munz: Isocoma menziesii.
