DISTRIBUTION AND OCCURRENCE
SPECIES: Quercus havardii | Sand Shinnery Oak 



GENERAL DISTRIBUTION : 
Sand shinnery oak grows from the Texas Panhandle and western Oklahoma to
northeastern New Mexico and Arizona, northward to southeastern Utah
[14].  It is a dominant plant throughout much of the southern Great
Plains [51] and grows on more than 3.4 million acres (1.4 million ha) in
north and west Texas [47].  Sand shinnery oak occurs as a dominant on an
estimated 5.7 million acres (2.3 million ha) in the Southwest [47].

HABITAT TYPES AND PLANT COMMUNITIES : 
Sand shinnery oak grows as a dominant in xeric, shrubby oak communities
in Texas, Oklahoma, and the Southwest.  It occurs in a variety of other
communities including mesquite (Prosopis spp.)-buffalograss (Buchloe
dactyloides) prairie [26], shortgrass prairie [53], and in parts of
certain southwestern pinyon-juniper (Pinus-Juniperus spp.) woodlands east
of the Continental Divide [48].  It also occurs as a codominant with
sand sagebrush (Artemisia filifolia) on many sandy sites throughout the
southern Great Plains.

It has been listed as a dominant in the following community type
classification:

Plant associates:  In the southern Great Plains, sand shinnery oak
commonly grows with sand sagebrush, sideoats grama (Bouteloua
curtipendula), little bluestem (Schizachyrium scoparium), buffalograss,
skunkbush sumac (Rhus trilobata), and honey mesquite (Prosopis
glandulosa) [26,35,50].  Little bluestem, big bluestem (Andropogon
gerardi var. gerardi), sand sagebrush, and sideoats grama are common
where grazing has not been too severe [3].  Sand sagebrush, soapweed
yucca (Yucca glauca), honey mesquite, and sand shinnery oak often
dominate on severely grazed sites.  In parts of west Texas and eastern
New Mexico, sand bluestem (Andropogon gerardi var. paucipilus), little
bluestem, sand dropseed (Sporobolus cryptandrus), pricklypear (Opuntia
spp.), soapweed yucca, honey mesquite, broom snakeweed (Gutierrezia
sarothrae), and threeawn (Aristida spp.) are common associates
[7,11,33,47].
