DISTRIBUTION AND OCCURRENCE
SPECIES: Quercus arizonica | Arizona White Oak 



GENERAL DISTRIBUTION : 
Arizona white oak is distributed from central Arizona to southwestern
New Mexico [59,66,77].  Scattered populations occur in western Texas and
northern Mexico.  In Mexico, the range of Arizona white oak extends from
the state of Coahuila westward to Baja California Sur [16,27,39,42,61].
It occurs in fewer than 20 locations in Baja California Sur and is a
species of concern in Mexico [40].

HABITAT TYPES AND PLANT COMMUNITIES : 
Arizona white oak is found in diverse communities along elevation or
moisture gradients from savannas, semidesert grasslands, and interior
chaparral [10,57] to Madrean evergreen woodland and pine-oak (Pinus
spp.-Quercus spp.) communities [7].  Arizona white oak is codominant
with Emory oak (Q. emoryi) and gray oak in the encinal mixed woodland
series and Madrean evergreen woodland series [9,19,38,52].  Arizona
white oak habitat series occur in savannas of New Mexico [19].  Arizona
white oak is an indicator species in dry Douglas-fir (Pseudotsuga
menziesii), Chihuahua pine (Pinus leiophylla var. chihuahuana),
ponderosa pine (P. ponderosa), and Apache pine (P. engelmanii) habitat
and community types [1,3,55,63].  Arizona white oak is dominant or
codominant in open and closed-canopy pinyon-juniper (Juniperus spp.)
woodlands [28,53].  Occasionally, Arizona white oak is an important
understory species in pinyon-juniper stands [58] and Mexican pinyon (P.
cembroides) forests [46].  Isolated Arizona white oak occur infrequently
in riparian woodland associations, such as Arizona walnut (Juglans
major) and Arizona sycamore (Platanus wrightii) community types with
permanent or semipermanent streams [43,44,69,73,75].  Arizona white oak
occurs on edges of interior chaparral of Arizona in communities such as
the Arizona white oak-yellowleaf silktassel (Garrya flavescens)-Emory
oak association [11,13,35,63].  Some of the publications in which
Arizona white oak is listed as a dominant or indicator species are:

(1)  Forest and woodland habitat types (plant associations) of Arizona
       south of the Mogollon Rim and southwestern New Mexico [3]
(2)  Forest habitat types south of the Mogollon Rim, Arizona and New
       Mexico [18]
(3)  Classification of mixed broadleaf riparian forest in Tonto National
       Forest [37]
(4)  A series vegetation classification for Region 3 [52]
(5)  A forest habitat type classification of southern Arizona and its
       relationship to forests of the Sierra Madre Occidental of Mexico [54]

       analysis of the south slope [82].

Woody species associated with Arizona white oak but not previously
mentioned in Distribution and Occurrence information include Arizona
madrone (Arbutus arizonica), Arizona rosewood (Vaquelina californica),
and coral-bean (Erythrina flabeliformis) [45,55].
