Analysis of Flora of the Trails of the Santa Rosa Plateau Ecological Reserve

This page was accidentally put online when I transferred my webhost, and is just a shell which is being work on.

Introduction

This page analyzes the most recent list of 456 taxa found on or visible from the trails of the Santa Rosa Plateau Ecological Reserve, as of September 2005. Every one of these species is contained on at least one of the Plant Trail Guides for the Santa Rosa Plateau Ecological Reserve. This list does not contain taxa only observed off-trail at the Santa Rosa Plateau Ecological Reserve or taxa observed only in the greater Santa Rosa Plateau area outside the Reserve.

This is a preliminary analysis, which will be redone when the final list of species is compiled from this year. Taxa are still being added to the list; the 456 taxa on this list represents 36 more taxa than the list produced on 9 June 2005.

The Completeness Of The Flora

There are three ways to measure the completeness of the trail flora:

Composition Of The Flora By Lifeform

The Distribution In California Of The Taxa

How widely distributed are the taxa found here? Are most of the taxa found here restricted to nearby areas of Southern California, or are they widely distributed through the state?

A related question is which area of Southern California is most-closely related to the Santa Rosa Plateau Ecological Reserve (henceforth SRP); i.e., how does the SRP fit in with its neighboring areas floristically.

The analysis here used the geographic range given for each taxon in the Jepson Manual. The geographic ranges that include the SRP or are very close neighbors are given in the following table:

JM AbbreviationFull Name
CAthe entire state of California
CA-FPthe California Floristic Region (excludes the Great Basin and Desert portions of the state)
PRPeninsular Ranges
SCoSouth Coast
The Jepson Manual gives a (see Jepson Manual Analysis: Number of Species by Geographic Region Resolved Into The Number Of Taxa From Successively Larger Areas).

The Distribution In The Santa Rosa Plateau Ecological Reserve Of The Taxa

Mention tweaks; list now contains one fewer taxa by combination of the subspecies of Hordeum murinum.
