Flora of Borrego Springs Desert Floor Area


Introduction
Checklist


Introduction

This flora is for the Desert Floor in the Borrego Springs area, especially the areas along the roads that people drive in the Borrego Springs area to look for wildflowers. See Fig. 1 for the boundary of this flora.

Fig. 1. The boundary for this flora of the Borrego Desert Floor is inside the pink boundary line.

This flora includes Borrego Springs itself, except for the developed portions of town, and the flattish areas surrounding it, such as along Coyote Creek Wash at the end of Di Giorgio Road and upstream; Henderson Canyon Road; the Visitor Center area up to the base of the mountains to the west; the Hellhole Canyon alluvial fan area up to the base of the surrounding mountains, etc. It does not include any species that are found only on the slopes above these flat areas; or only in the Badlands or Borrego Mountain; etc.

This checklist does not include weeds found in the town of Borrego Springs bordering developed areas, planted specimens, or specimens growing in any irrigated area.

See also Desert Floor Survey on 14 March 2017 to see which species were found at the locations surveyed on that day.

Checklist for Borrego Springs Desert Floor Area

See:

An asterisk before the common name indicates a species not native to the Borrego Valley. That includes Baileya multiradiata, which has been seeded along the southern part of Borrego Springs Road in the town of Borrego Springs.

Many of these species grow only on the edge of the desert floor near the base of the surrounding mountains. Those species are identified in the last column as being "edge" species. Presumably, if the surrounding mountains were not in this area, the non-edge species are the only ones that would be seen.

There are numerous additional species that grow right at the edge of the desert floor at the base of the surrounding mountains. Those species are not given in this list.
