Introduction

This is a very preliminary checklist for the area that includes Tahquitz Peak, Red Tahquitz Peak, the ridgeline between them, and a short ridgeline to the north of Tahquitz Peak. It has been compiled from online vouchers, from fieldwork on 23 and 28 July 2008, and from the portion of our plant trail guides in this area. Most online vouchers have not yet been reviewed for reasonableness.

A few vouchers from the fieldwork (Gayophytum, Juncus and a few grass species) have not yet been determined, and hence are not present in the checklist below. Species abundances from the plant trail guides have not yet been added below.

Even though this checklist is only very preliminary, we've placed this online for three reasons:

1. It will be useful to a number of people;

2. It is interesting; and

3. Lists have to start with something. With even a preliminary list, botanists can check to see if an observed or vouchered taxon is on the list, and if not, it can be added. Please let us know if you run across a voucher, or see a species, in this area that is not on this list!

Location

The following map shows the location of the floral area targeted here:

The dashed purple line delineates the boundary, which follows roughly the 8200 foot elevation contour. Solid blue lines are trails, each of which have been botanized extensively (see the plant trail guides for each one). Note that the PCT has been rerouted in places from the trail shown on the base map. Dashed blue lines are floristic surveys done once each so far that compiled checklists and estimated plant species abundances. The one near Tahquitz Saddle was done on 23 July 2008; the one at Red Tahquitz was done on 28 July 2008.

The area is shown in this photograph taken by James Dillane from Wellman Divide on 7 August 2007:

The floristic area boundary is only roughly drawn in this picture. Refer to the topographic map above for its precise location. See also picture without labeling, and pictures taken by James Dillane from the south side in Garner Valley on 3 September 2007: with labels and without labels.

The 8200 foot contour was chosen for several reasons:

• It includes all ridgelines that are clearly associated with Tahquitz Peak and Red Tahquitz Peak. The 8400 foot contour includes only a very small area around Tahquitz Saddle, and is discontiguous due to the 8408 foot elevation peak in the northeast portion.

• It cleanly separates the area of the peaks from Little Tahquitz Meadow below 8100 feet, which contains a very different suite of plant species;

The floristic area boundary was modified to be a bit higher than the 8200 foot contour on the north, in order to avoid extending that ridgeline into the Saddle Junction Area. It was modified to be a bit lower along Little Tahquitz Creek, in order to make a clean boundary at the junction of the PCT and Little Tahquitz Valley Trail.

Important Caveats

Please note the following important caveats about this preliminary Checklist:

• We have not looked at any of the vouchers yet, so we cannot vouch for their determinations. We have checked only the names of the taxa to make sure it was not unreasonable for them to occur here.

• This is a very preliminary first draft Checklist, compiled quickly and without review by other knowledgeable botanists, and so well may contain bonehead errors.

Checklist for Tahquitz and Red Tahquitz Area

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 would indicate a non-native taxon, but all of the taxa found so far here are native.

The fourth column gives information about whether we have observed a given taxon (O), whether it has been vouchered in this targeted area (V), whether it was observed or vouchered from the immediate area of Tahquitz Peak (T), Red Tahquitz Peak (R), or the Tahquitz Saddle Area (S), and whether the taxon is only found in a wet area such as a seep area or along a moist drainage (W).

The last two columns give a rough estimate of the number of plants and the number of locations for each species, for taxa seen in our field surveys of the Red Tahquitz Area (R) and of the Tahquitz Saddle Area (S). Maximum values are 99 plants, and 9 locations. The main intent of this column is to indicate the species for which we found few plants or locations.

This is a working list, about which we make no guarantees at all until we officially release it. Use at your own risk!
