DISTRIBUTION AND OCCURRENCE
SPECIES: Adenostoma fasciculatum | Chamise 



GENERAL DISTRIBUTION : 
Chamise is the most characteristic and widely distributed chaparral
species in California [25,38,121].  It is most extensively distributed
in the southern Coast Ranges [20,26,48], but occurs in the Coast,
Transverse and Peninsular ranges from Mendocino County to Baja
California [20,26,48].  It also occurs in the Sierra Nevada foothills
[121] and on the Channel islands [26].  Adenostoma fasciculatum variety
obtusifolium is restricted to southwestern San Diego County and Baja
California [26,92].

HABITAT TYPES AND PLANT COMMUNITIES : 
Chamise is a shrub component of chaparral, woodland, and forest
communities throughout much of California [13,51].  Within chaparral
communities, chamise typically dominates the shrub cover on the hottest
and driest sites [102].  As available moisture increases, it codominates
with manzanita (Arctostaphylos spp.) and ceanothus (Ceanothus spp.)
species [42,51].  Chamise is an understory shrub in dry coniferous
woodlands dominated by Parry pinyon (Pinus quadrifolia), knobcone pine
(P. attenuata), or gray pine (P. sabiniana).  Less commonly, chamise
occurs beneath scrubby "forest" communities dominated by either Torrey
pine (P. torreyana), knobcone pine, Piute cypress (Cupressus arizonica
ssp. nevadensis), Cuyamaca cypress (C. a. var. stephensonii), or Tecate
cypress (C. forbesii) [51].  It is also present in the understory of
maritime Coast Range ponderosa pine (Pinus ponderosa) forests [51].

Common associates within chamise chaparral include [13]:  

   northern Coast Range:  hoary manzanita (Arctostaphylos
        canescens), Parry manzanita (A. manzanita), wedgeleaf
        ceanothus (Ceanothus cuneatus), wavyleaf ceanothus (C.
        foliosus), and leather oak (Quercus durata).

   southern Coast Range:  oaks (Quercus spp.), ceanothus (Ceanothus
        spp.), manzanitas (Arctostaphylos spp.), buckthorns (Rhamnus
        spp.), sumacs (Rhus and Malosma spp.), California sagebrush
        (Artemisia californica), California buckwheat (Eriogonum 
        fasciculatum), and sage (Salvia spp.).

   interior:  whiteleaf manzanita (Arctostaphylos viscida), Parry
        manzanita, wedgeleaf cenaothus, Lemmon ceanothus (C.
        lemmonnii), chaparral whitethorn, toyon (Heteromeles
        arbutifolia), buckthorns, poison-oak (Toxicodendron
        diversilobum), and yerba santa (Eriodictyon californicum).

   southern California:  bigberry manzanita (A. glauca),
        Mexican manzanita (A. pungens), pink-bracted manzanita
        (A. pringlei var. drupacea), hoaryleaf ceanothus (C.
        crassifolius), and desert ceanothus (C. greggi var. perplexans).
