Plant Checklist for Whitewater River Canyon, San Bernardino Mountains

Plant Checklist for Whitewater River Canyon, San Bernardino Mountains

Introduction
Checklist

Introduction

This is a start at a flora of this area, compiled from vouchers and from surveys we have done in this area.
The checklist presented here adds the results from a survey done on 18 March 2010 to the checklist previously compiled from vouchers and from previous surveys by Michael Charters. For details and caveats on that list, see Plant Voucher Checklist for Whitewater River Canyon. In particular, note that some of the determinations made from vouchers alone are highly suspect, such as the Ericameria laricifolia. This is a species found mostly in the eastern Mojave Desert, and is unlikely to actually occur here.
The 18 March 2010 survey added 13 taxa (10 native, 3 non-native) to the previous checklist, resulted in improved determinations for 3 other taxa, and produced abundance estimates for all of the 169 taxa observed in that survey.
Pictures of some of the species from the 18 March 2010 survey, as well as from previous surveys by Michael Charters, are here: February 2009; April 2009 Part One; April 2009 Part Two; and 18 March 2010
The survey on 18 March 2010 was done in five separate locations, shown on the following map:

A brief description of the locations is given in the next table:
Some Characteristics of the Survey Locations

# Survey Length
(miles) Elevation Range
(feet) Description
1 ~0.3 1350 East end of Whitewater Bridge on Whitewater Cutoff Road just north of I-10
2 ~0.2 1800 Seep area along Whitewater Road about 2.4 miles north of the south end of Whitewater Road
3 0.75 2100-2500 South end of the Overlook Trail, beginning about 3.9 miles north of the south end of Whitewater Road
4 2.5 2200-2700 Canyons on east bank of Whitewater River, north of the Whitewater Visitor Center, beginning about 4.5 miles north of the south end of Whitewater Road.
5 1.0 2200-2400 Canyon base immediately west of Whitewater Visitor Center, about 4.5 miles north of the south end of Whitewater Road.

Checklist for Whitewater River 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 next four columns specify where in Whitewater Canyon each taxon was recorded, along with an idea of the abundance for each species, either through the number of vouchers in different areas, or from our survey. The columns are given roughly in order of descending elevation in the Canyon, which is mostly from north to south.
The first column, titled UC, gives the number of vouchers in the Upper Canyon, the part in San Bernardino County. Similarly, the last column, titled LC, gives the number of vouchers in the Lower Canyon, the part in Riverside County.
The second column, titled ID Survey #Plants, does double duty. First, it indicates those taxa whose determination is uncertain. If the determination is fairly likely, a ~ is the first character in that column. If the determination is just a guess, a ? is the first character.
The rest of the column gives the plant abundance from the 18 March 2010 survey, as the maximum number of plants / number of locations from any of surveys #1-4. In those surveys, we estimated the minimum plant abundance in each survey separately. Maximum values are 99 plants and 9 locations (surveys #1 and 2 were only at a single location). Survey #5 was used primarily to try to find additional species. For those species, estimates of abundance were made and given in this column. If only a single number of 1 is given in this column, the species was only found in previous surveys by Michael Charters, where no abundance estimate was made.
Note that many plants are more abundant than we found in surveys 1-4. All we can do of course is report on the abundance of plants in the areas we have surveyed. For example, we've been told that chamise, Adenostoma fasciculatum, is very abundant along the Overlook Trail, but we found no chamise at all in survey #3, which covered only a portion of the lower southern end of the Overlook Trail. In fact, we found only a single chamise plant in survey #4. It was more abundant in survey #5, but no abundance estimate was made during that particular survey.
The third column, titled Survey #, indicates in which survey each taxon was found. Survey #1-5 are as in the map above; survey #6 indicates one of the previous Michael Charters surveys. When a taxon was found in multiple surveys, each of the survey numbers is given.
This is a working list, about which we make no guarantees at all. Use at your own risk!
