Species Checklist


This checklist is for the Carrizo Canyon area west of S2 except in the immediate vicinity of S2 on the east, from Torote / Indian Canyon on the north to the upper end of the Carrizo Canyon Jeep Trail on the south. It includes Rockhouse Canyon and Bow Willow Canyon.

Procedure For Compiling The Checklist

The Checklist was compiled from two sources:

The fieldwork was used to compile a species list, with a GPS location for at least one occurrence of every species, and to estimate abundances for each observed species. Note that the fieldwork list is incomplete for annuals and perennials, since it was made from a field trip in a low rainfall year and before most annuals had begun to bloom.

The fieldwork found 93 distinct taxa that could be fairly reliably identified, plus abundant Nemacladus skeletons that could not be identified to the species.

Vouchers were obtained from three separate searches:

Duplicate vouchers were removed, and the localities were reviewed manually to remove ones not in the target area.

Two vouchers were discarded as having improbable determinations:

That left 982 vouchers, of 277 distinct taxa.

The top collectors in this area are (table needs to be updated):

# VouchersCollector(s)
85Larry Hendrickson et al
34Joe Barth
28Jon P. Rebman et al
14Ian Cain, Emily Clayton

A few additional taxa were included in the list, either from species observed on the Sweeney Canyon survey or given in a CNPS checklist for this area, as long as they had vouchers quite close to this area. Those species can be identified in the checklist since they have no entry in either the voucher or Carrizo Creek survey column.

The union of the checklist from the fieldwork and the vouchers contains 290 taxa. Of those 290 taxa, TBD taxa were found only in the vouchers; TBD taxa were found in both the fieldwork and the vouchers; and TBD were found only from the fieldwork.

Checklist for Carrizo Creek Area

The Checklist follows the 2012 Jepson Manual Second Edition with only a few exceptions.

The Checklist is sorted first by the eight evolutionary categories (clades) used in the 2012 Second Edition Jepson Manual - lycophytes, ferns, etc., to eudicots and monocots - and then by family and scientific name. The clades are labeled in the Checklist. Note that this changes the order of presentation of the taxa from that of the 1993 First Edition.

The family name is abbreviated to the first five characters in order to save space in the table rows.

An asterisk before the Common Name indicates a non-native taxon.

The scientific name is linked to the latest online Jepson Manual description for each species, which also gives the months in which each species flowers. That link also gives a map of where the species occurs in California; a plot of elevation vs. latitude for California; and a histogram of the voucher collections by month.

A few species may not have working links, if their names have been updated more recently (such as Mimulus diffusus, which is still listed under M. palmeri in the online flora), or if they are reserved-judgment taxa which are listed in the entry for another taxon name. However, as of 16 January 2013, the Jepson Manual links have all been updated to link to the parent species for the taxa without their own entries. Taxa linked to anything other than the Jepson Manual link for the full scientific name used below have been indicated with a ^ after the scientific name, and are discussed here.

The common name for most species in the checklist is linked to Calphotos to give pictures of most taxa. Of course, there is no guarantee that the Calphotos pictures are correctly identified.

Note that the link will not always return pictures, since not every species has pictures at Calphotos, and a number of species still have their Calphotos pictures under the Jepson Manual First Edition Names. Some links have been made to the Calphotos pictures using the First Edition Jepson Manual name, if there are no pictures under the Second Edition name. Of course, that may result in a link with no pictures if those the names of those Calphotos pix are updated in the future to the Second Edition names.

Note also that the links below will return only the specified taxon at Calphotos, and not any subtaxa; i.e., a link to Cryptantha barbigera will not return photos of Cryptantha barbigera var. barbigera. There may be additional pictures at Calphotos under a different scientific name such as the First Edition Jepson Manual name.

Some links go to special pages with more information on those species.

The column with header #V give the number of vouchers found in this area.

The column with header #Pls gives a rough estimate of the minimum number of plants that we saw, with a maximum value of 99 plants. The main intent of this column is to indicate the species for which we found very few plants.
