Flora of Rodriguez Truck Trail Area, Anza-Borrego Desert State Park

Introduction
Checklist

Introduction

This flora is for the Rodriguez Truck Trail Area = Rodriguez Canyon Area, from the head of Mason Valley to somewhat below the junction with the PCT. It has been made from vouchers, from three surveys of canyons on the southwest side of Granite Mountain, one survey of the lower Rodriguez Road area, and one survey of the lowermost portion of Oriflamme Canyon. This flora covers an elevation range from ~2500 feet to ~3400 feet.
The PCT area is covered in a separate flora.
More details and a map will be supplied in the future.
