INTRODUCTION
Anril 1. 1962
(Revised slightly,
March 26, 1971, byJ. H. Thomas.)
Jasper Ridge and Searsville Lake have long been an important collecting area
for the botanists and students of Stanford University. Botanical collections
were first made in this area about 1860 by H. N. Bolander and have continuedto the present.
Many theses and scientific papers have been written that bear partially or
directly on the area. Those that have been used in the present study are those
b,y Cooper (1922), Chaney (1925), Springer (1935), Moeur (1947), and Thomas (1958,1961). The nomenclature used is the same as that in the latest flora of the area
(Thomas, 1961). The standard floras of California (Abrams & Ferris, 1923-1960;Jepson, 1909-1943, 1925; MUnz, 1959) have been consulted.
THE VEGETATION OF THE JASPER RIDGE BIOLCGICAL EXPERIMENTAL AREA
The vegetation ,of Jasper Ridge may be divided into five distinct associations.
These are oak-madrone forest, oak-woodland, chaparral, grasslands, and the aquaticflora of Searsville Lake. The areas of transition between the first four associa
tions may be either gradual or abrupt, so there mayor may not be an intermingling
of their species complexes. In the following lists, only those species either
confined to, or indicative of, an association will be listed for that association.
The more densely wooded forest, occurring mainly upon the steep north-facingslopes of the ridge, may be termed the oak-madrone forest. The dominants are
Quercus ap.rifo1ia and Arbutus Inp.nziesii. Indicative species are:
trees: ~lercus a~rifo11a
Quercus kelloe~ii
Umbellularia ca1ifornica
shrubs: Rosa californica
Rosa evmnocarpaRubus ursinus
Holodiscus discolor

The streambank vegetation along San Francisquito Creek may be included as a sub
unit of the oak-madrone forest association, as the two types here intermingle, with
many of the species common along the creek being found along its minor tributaries
in the oak-madrone forest. Some of these species are also found along Corte deMadera Creek and the moist ravines above Searsville Lake. These are:
trees: Seouoia sempl"Jrvirens
§Alli laevt!:!at,e

The more openly yooded forest, occurring upon the flatter, gently sloping areasof the ridge may be termed the oak-woodland. The characteristic species is Qnercusdouglasi!. Species indicative of this association are:
trees: Quercus douelastt
herbs: Calochortus Albus

The chaparral association is found on the gentle south-facing slopes and flatter
-2-
8~eas on the crest of the ridge. The dominants are Adenostoma fasclculatum, CeR"othuscuneatus var. d~bius, and Arotostapbylos crustacea var. crustacea. Indicative
species are:

Much of the Jasper Ridge, especially along its crest, consists of grasslands.
Most of this association is on flat or gently sloping land, but in many placesit extends up and over the steeper slopes where the original chaparral has been re
moved to provide for more grazing area. Here and there, especially on the steeper
slopes, individuals of Quercus sQrifolia, Q. douelasi\, and Q. kelloei~ may beencountered. Typical grassland herbs are:
