Flora of Smoke Tree Canyon


Introduction
Checklist


Introduction

This checklist is a start at a flora of the Smoke Tree Canyon. It contains a list of the species with reasonably-certain identifications from a single survey on 26 February 2008, as well as the species vouchered and found from a fairly-large surrounding area.

The Smoke Tree Canyon area is delineated by the red rectangle in the following map:

The route surveyed on 26 February 2008 is shown in red on the following map:

There is a fairly large area for parking along either side of the road at mile marker 34.5 on S22.

The survey on 26 February 2008 covered 2.2 miles from elevation 920 feet to 1560 feet, and thus did not cover the full extent of the Canyon to the natural rock tanks shown in the above map.

The survey found 80 taxa that could be fairly-confidently identified, given in the checklist below, along with five other species that could not yet be fully identified. Those species were: an unknown grass perhaps developing an inflorescence like Achnatherum; a suncup with no basal rosette; a Boerhavia species with a mostly terminal inflorescence with short peduncles; and two Ephedra species, one possibly similar to E. viridis and the other possibly similar to E. fasciculata var. clokeyi.

The locations of (generally) the first occurrence of all 85 taxa are shown in the plot below:

Some taxa were found at the same location, especially near the beginning of the survey, so there are fewer than 85 points plotted above.

Usually, most of the taxa in any survey are found near the starting point, but the above plot shows that we continued to encounter significant numbers of new species going up the canyon.

The checklist below also contains species vouchered from a much larger area, the the southeast Santa Rosa Mountains north of S22 and the Borrego Badlands south of S22, as well as a few taxa found only from surveys in the nearby areas listed below.

Checklist for Smoke Tree Canyon

The Checklist is sorted first by category - ferns, gymnosperms, dicots, and monocots - and then by family and scientific name. The Family and Scientific Name are from the Jepson Manual, with the family name represented by its first three letters (see Plant Family Abbreviations). An asterisk before the Common Name indicates a non-native taxon.

The column labeled # Plants/Areas indicates whether a taxon was present in the 26 February 2008 survey, and give a rough estimate of the number of plants and number of locations for each species in the entire survey. Maximum values are 99 plants, and 9 locations. The main intent here is to indicate the species for which I found very few plants or locations.

The final two columns give the number of vouchers for each taxon found in the southeast Santa Rosa Mountains north of S22 (SRM) and the Borrego Badlands south of S22 (Badland).

A few additional taxa from other surveys in the southeast Santa Rosa Mountains are also included. Those taxa have no entries in the last three columns. The other surveys are: the nearby Villager Peak Trail, Palo Verde Canyon and Palm Wash / Calcite Mine Area, and The Extreme Northeast Corner of San Diego County.
