DISTRIBUTION AND OCCURRENCE
SPECIES: Quercus pungens | Sandpaper Oak 



GENERAL DISTRIBUTION : 
Sandpaper and Vasey shin oaks are widespread throughout the Edwards
Plateau and Trans-Pecos region of Texas.  Scattered, isolated
populations continue southward into the state of Tamaulipas and proceed
westward into Chihuahua, Mexico [10,21,27].  Populations of sandpaper
oak extend northward into the Guadalupe Mountains of Texas [16,21] and
westward to the mountains of southwestern New Mexico and southeastern
Arizona [17].  Sandpaper oak has been reported from southern Colorado
[4]; however, Harrington [14] was unable to locate any specimens
supporting this range extension.

HABITAT TYPES AND PLANT COMMUNITIES : 
Sandpaper oak occurs with true mountain-mahogany (Cercocarpus montanus)
and desert ceanothus (Ceanothus greggii) as a dominance type in the
chaparral formations in the Guadalupe Mountains, Texas [9,26] and the
montane chaparral of the Chihuahuan Desert region [15].  Sandpaper oak
is a characteristic member of juniper (Juniperus spp.)-oak (Quercus
spp.) communities and intermixes with desert scrub savanna in the
canyons of central and western Texas [8,33].  In Texas sandpaper or
Vasey shin oaks are a dominant or characteristic species in the Mohr
shin oak (Quercus mohriana) series, oneseed juniper (Juniperus
monosperma) series, and sandpaper oak-true mountain-mahogany series [33].
Sandpaper or Vasey shin oaks are dominant species in the following
publications:

(1) Vegetation and community types of the Chihuahuan Desert [15]
(2) Plant communities of Texas (Series level) [33].

Several species that were not previously included in Distribution and
Occurrence information but occur with sandpaper oak are cane cholla
(Opuntia imbricata), purplefruited pricklypear (O. phaecantha), Mexican
buckeye (Ungnadia speciosa), Texas persimmon (Diospyros texana), hairy
tridens (Erioneuron pilosum), and plateau oak (Quercus fusiformis)
[7,8,9,22].
