Flora of Fish Creek Mountains, Imperial County

Fig. 1. The Fish Creek Mountains in southwest Imperial County. The thick blue line shows the route surveyed on 19 December 2014 by the authors. The circled numbers show the number of vouchers at those locations. The small number of other vouchers generally do not have precise positions. Some of the border lines of Anza Borrego Desert State Park are marked by thin blue lines with arrow tips.

This flora is just a start at a flora of the Fish Creek Mountains, since very few locations have been surveyed or vouchered. In fact, as far as we know, there are no surveys or vouchers from anyplace except in the flattish areas at the base of the Mountains.

This flora was compiled from vouchers; from a field survey of the USG Plaster City Quarry by Scott White in June 2005; and from a field survey on 19 December 2014 by the authors.

Vouchers were searched on 20 December 2014 at the Consortium of California Herbaria for Imperial County vouchers with the words Fish Creek in their locality. The localities of all vouchers were reviewed, and ones with localities that were clearly outside the immediate area of the Fish Creek Mountains were tossed. One voucher of Salix orestera from the Fish Creek Mountains at 4500 feet was tossed, since this was likely taken from the Sierra Nevada, where that species lives. Another voucher of Eschscholzia hypecoides is almost certainly a misdetermination of E. parishii, and thus E. hypecoides was rejected from the list.

The resulting accepted voucher list contained 161 vouchers of 71 species. The dominant collectors were:

Scott White also compiled a detailed plant checklist for the USG Plaster City Quarry in June 2005, with information on abundance and habitat of each species. That list contains 98 taxa.

The authors surveyed a 6.0 mile loop on 19 December 2014, of the alcove on the north side of the Fish Creek Mountains, of the area south of mile 4.0 to mile 6.0 on the dirt road that parallels the railroad tracks, where mile 0.0 is at Split Mountain Road. A total of 74 taxa were found.

The union of these three lists contains 149 taxa, after rectification of the combined list by assigning taxa just given to species to the subspecies, if one was given in one list.

In the following checklist, the columns are as follows:
