Flora of Smoke Tree and Coachwhip Canyons


Introduction
Checklist


Introduction

This checklist is a start at a flora of Smoke Tree and Coachwhip Canyons. It contains a list of the species with reasonably-certain identifications from one survey of Smoke Tree Canyon on 26 February 2008, augmented by a few species from its junction with S22 on 2 April 2010, and two surveys of Coachwhip Canyon on 28 November 2008 and 24 February 2009. It also includes species vouchered and found from the neighboring area north of S22, from the Villager Peak Trail to the Truckhaven Rocks, since many of those may prove to be present in these canyons.

The list of species is essentially the same as given in the Flora of Southeast Santa Rosa Mountains, but this version gives the number of plants found in the surveys for Smoke Tree and Coachwhip Canyons.

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

The rest of this text has not been updated since 1 December 2008, except for the checklist.

The route surveyed on 26 February 2008 is shown in red on the following map; the route surveyed on 28 November 2008 is shown in green:

There is a fairly large area for parking along either side of the road at mile marker 34.5 on S22 for Smoke Tree Canyon, and at mile marker 34.8 for Coachwhip Canyon.

Smoke Tree Canyon Survey

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.

Coachwhip Canyon Survey

The survey on 28 November 2008 covered 2.8 miles from elevation 910 feet to 1400 feet.

The survey found 53 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: two different Cryptantha species, at least one of which was very abundant; a perennial small grass; an abundant dead annual with broad basal leaves and capsule fruit; and an unknown very abundant dead Asteraceae annual.

Note that the Coachwhip Canyon Survey is very incomplete for annuals and perennials, since it was done in late November.

Checklist for Smoke Tree Canyon

See:

An asterisk before the common name indicates a non-native species.

The last two columns give the minimum number of plants observed in the sum of all field surveys, up to a maximum number of 99, for each canyon; CW for Coachwhip and ST for Smoke Tree. A V in this column indicates a species vouchered from that canyon but which we have not yet observed.
