Shinnery is scattered throughout the western third of Oklahoma principally on coarse soils derived from materials of the Pliocene and Pleistocene epochs. It occurs on sandy soils (Brownfield and Nobscott series) throughout the mixed prairie and short grass plains in a region of low precipitation (20 in. to 25 in.). The most common species is Quercus Havardi, although Q. stellata, Q. Margaretta and Q. Mohriana are present. The shinnery constitutes an oak population of extreme hybridity with Q. Havardi x Q. stellata being the most common hybrids. Most stands of shinnery are two to four feet high, although the height may vary from one to 40 feet. Since no germination of acorns was observed, it is assumed that reproduction is accomplished largely by rhizomes. Fire is utilized to control the height of the shin oaks and to promote an increase in forage whereas the herbicide, 2,4,5-T, when used for three successive years, eliminates much of the shinnery.
