Plant Communities and Floristics

(Plant community info to be supplied.)

The following summary was made using the trail list after the 2/13/04 fieldwork, and has not been updated from later fieldwork.

The Trail plant list contains 190 taxa, of which 183 have so far been identified, in 3.49 unique miles of trail. Of these 183 taxa, 44 (24%) are non-native.

I have plotted these numbers against the other trails in my database. The plots show:

Number of Unique Taxa On This Trail

The following histogram gives the number of trails in my database that contain each taxon on this trail. I had 90 trails in my database when this histogram was made; 4 of those trails, including this one, are at the Santa Margarita Ecological Reserve. A number of "1" means the taxon has only been found on this trail among the trails in my database; numbers of "4" or smaller may indicate taxa found only at the Santa Margarita Ecological Reserve.

The table above does not contain the two taxa in the orchard that are not numbered in the guide. I found 6 additional species not in the above table, since they have not been identified yet. The unidentified ones are marked with ? or sp in the id? column in the guide, and do not have any number given in the #all column.

The taxa that are truly unique, or almost unique, to this trail or area, out of the 73 trails in my database on 16 February 2004, are:

#allLatin NameCommon NameDistribution in Southern California / Distribution in Trail Guides
1Chloris virgata*feather finger grassSCo. This weed is not on the trail; it is found in the orchard prior to the beginning of the plant guide.
1Lemna sp.duckweedTBS. Duckweeds appear in only in two guides: here on the Santa Margarita River and on Palomar Mountain on Pauma Creek at the Weir. Note that the species here is so far unidentified, and could be the same species as at Palomar.
1Medicago sativa*alfalfaCA.
1Muhlenbergia microspermalittleseed muhlySW.
1Navarretia intertexta ssp. propinquaneedleleaf navarretia-. Oddly, the Jepson Manual doesn't place this in Southern California. However, Munz has it cismontane and montane from San Diego County north.
1Oxalis albicans ssp. pilosaCalifornia oxalisSCo, ChI, WTR. There are two other observations of Oxalis albicans: one not identified to subspecies on the south Santa Margarita River Trail ~5 miles southwest, and one of ssp. californica on the Los Santos Trail at the Santa Rosa Plateau ~5 miles northwest.
2Apium graveolens*celeryCA. Found only at SMER at the Santa Margarita River.
2Aristida adscensionissix-weeks three-awnSCo, s ChI, WTR, SnGb, PR, D. Found also at Monserate Mountain in Fallbrook, ~5 miles south.
2Baccharis emoryiEmory's baccharisSCo, WTR, PR, D. Found only at SMER, plus another occurrence just off-trail on the Vista Grande Trail at the Santa Rosa Plateau.
2Caulanthus heterophyllus var. pseudosimulansslender-pod jewelflowerTR, n PR. Found only at SMER. Note that this id is not 100% yet.
2Euthamia occidentaliswestern goldenrodCA. Found only at the Santa Margarita River at SMER on our trails.
2Juncus textilisbasket rushn&c SW. Found only at SMER on our trails. Note that the id is not 100%, since I haven't seen the plant bloom yet.
2Kickxia spuria*roundleaf fluellinCA-FP. Found only at SMER. This weed is not on the trail; it is found in the orchard prior to the beginning of the plant guide.
2Tetracoccus dioicusParry's tetracoccusRARE. s SCo (San Diego County), w PR; Baja CA. Found also at Monserate Mountain, ~5 miles south.
3Cheilanthes newberryicotton fernSW. Found only at SMER and the south Santa Margarita River Trail.
3Scirpus americanusAmerican tuleCA. Found only at SMER and the Los Jilqueros Preserve in Fallbrook, ~5 miles southwest.

Note that many of these taxa are found only along streams or on ponds, and are uncommon among my trails simply due to the lack of streams with perennial water, and ponds, along most of my trails.

Fieldwork Dates and Summary of List Changes With Time

The following table gives the dates the trail was walked and taxa recorded. After each visit, the table gives the total number of taxa on the list and the breakdown of the taxa without positive identification. See Explanation of Plant Trail Guides to understand the symbols below.

Visit DateVisit ## taxa# "?"# "sp"# "~"# "ssp"

The unknowns were not broken down further than ? prior to 8/3/02.

The fieldwork on 7/5/04 was limited to the Temecula Gorge area, and a spotcheck at one other location on a single unknown species. The fieldwork on 8/16/04 was entirely confined to the Santa Margarita River crossing. The fieldwork on 1/29/05 was limited, since that was mostly just a hike. The fieldwork on 4/3/05 was just to mile 1.34. The fieldwork on 4/15/05 was limited to the Temecula Gorge area. The fieldwork on 8/20/05 was limited to the Stone Creek and Temecula Gorge areas.

Comments On Specific Species

Juncus textilis. These plants considerably surpass the 1-2 m heights given in Munz and the Jepson Manual, being a minimum of 2.5 m high (voucher TC721). The voucher specimen was one of the few stems with blooms; there are longer stems here.

I thank Jane Strong for her considerable assistance with helping me with some of the identifications, and for her help on one of my field trips.
