Checklist

Introduction

This checklist gives the results of a botanical survey on 9 May 2009 by the authors listed at the bottom of this page, conducted for the Friends of Rattlesnake Canyon, as well as the species on the botanical inventory of that canyon prior to that survey.
Checklist for Rattlesnake Canyon

The Checklist is sorted first by category - ferns, dicots, and monocots - and then by family and scientific name. The Family and Scientific Name are from the Jepson Manual. An asterisk before the Common Name indicates a non-native taxon.
The column GPS # 5/9/09 gives the GPS locations for each observed species. Plants that were not identified to species are indicated in that column by sp.
The column RSC List 5/1/09 gives the taxa that were on the botanical inventory of that canyon prior to our survey.
