Santa Margarita Ecological Reserve: Preliminary Plant List by Trail

This is a working list, about which I make no guarantees at all until I officially release it. Use at your own risk!

Summary Statistics

Both the list from Simpson (2000) and from myself (Chester 2003) are incomplete, and are works in progress. Nonetheless, I thought it would be interesting to make a comparison of the numbers so far. These numbers will change significantly in the future.

My list was compiled from my plant trail guides as of 26 December 2003.

Note that Simpson's list is for the entire Santa Margarita Ecological Reserve, whereas my list is compiled solely from taxa seen along the main roads and one trail (collectively called routes below). Hence one would expect that Simpson's list would contain significantly more taxa than my list.

Also, I have in general retained taxa in Simpson's list that are only identified to genera, whereas I have not listed such taxa from my plant guides. This was solely because I had his unidentified species in my database, whereas I do not put my unidentified species in my database. The only exception was Simpson's Sanicula sp., which I left off the merged list due to my positive identification of Sanicula crassicaulis.

Finally, most of my lists were compiled during the drought year of 2001-2002, and hence are known to be very incomplete, especially for annuals.

Due to these differences, and the serious incompleteness of both lists, interpretation of these numbers is hazardous!

Total number of taxa: 388.

Number of taxa in each list: 325 from Simpson; 233 from Chester.

Number of taxa in common between the two lists: 170.

Number of additional taxa from Simpson's list over that of Chester's list alone: 155.

Number of additional taxa from Chester's list over that of Simpson's list alone: 63.

Number of the 233 taxa from Chester found on each of the following routes:

RouteAbbreviation# of taxa
North Gate to GorgeN117
North Rim TrailNR62
South Gate to GorgeS192
Stone Creek LoopSC111

The abbreviations are used in the table below to identify where the taxa are found.

These numbers actually fit together pretty well, and are not terribly inconsistent with expectations from the normal distribution of plants, given the incompleteness of both lists:

# of routes# of taxa

Thus 26 taxa were found on all four routes, 47 taxa were found on three of the four routes, etc., with most taxa being found only on a single route or not being found on any route.

The only obvious problem seen in the above numbers is that the number of taxa found on just a single route is probably too low relative to the number of taxa found on multiple routes. See, for example, the same distribution from the Santa Monica Mountains. This is undoubtedly the case, since I expect that a lot of such taxa will be picked up from surveys in a normal rainfall year.

The Preliminary Plant List

Some of the plant identifications on the trails made by myself have come from the use of Simpson's list, and so are not necessarily independent confirmations of that identification. Such independent confirmations will be made in the future.

The list below undoubtedly contains some misidentifications. It also contains some taxa where the subspecies assignments are different, or not given in one list or the other. These will be resolved in the future.

An asterisk (*) before the common name indicates a non-native taxon.

I have corrected the subspecies of Quercus agrifolia from var. oxyadenia to var. agrifolia in Simpson's list per Simpson 2001, personal communication.
