Introduction

This trail is within the James Reserve, which is closed to the public except by advance arrangement for scientific or educational purposes.

This is a ~1.0 mile loop hike, with ~400 feet of elevation gain and loss.

This guide was originally created on a preview trip for a Sierra Club Natural Science Section outing on 28 July 2007, with additional work done on the guide on 4 May 2013; 14 June 2016; 6 and 9 July 2016; and 25 September 2020.

Some of the original determinations were made from the James Reserve Plant List, which made the identification task much easier. We thank Ken Berg for originally creating that list, all the collectors who contributed to that list, and the James Reserve staff and the UCR Herbarium for updating that list in March 2007.

The plant guide now has only one species with an uncertain determination, the probable Cerastium glomeratum at mile 0.02.

We thank Michael Hamilton and Jennifer Gee for permission to botanize the James Reserve, and for their hospitality during our visits.

Comments On Specific Species

Rhamnus tomentella ssp. cuspidata. The first specimen on the trail has the glabrous leaves of R. californica. The second specimen, also noted in the guide, has leaves that are soft hairy underneath. This is typical of this species at SnJt, leaving it less than clear which of those two names to call these plants. In this guide, we have adopted the name in the James Reserve Flora, but in other plant trail guides at SnJt have called these plants R. californica.

Ceanothus palmeri / C. integerrimus. These taxa are also extremely close, but it appears that the expert, Dieter Wilken, has settled on C. palmeri for the SnJt plants. Most of the plants we've checked have indeed been prominently 1-veined from base, fitting C. palmeri.
