<p>Post oak is a valuable contributor to wildlife food and cover. Considered a beautiful shade tree for parks, post oak is often used in urban forestry. It is also planted for soil stabilization on dry, sloping, stony sites where few other trees will grow. The wood of post oak, commercially called <a data-inlink="2g4tePlFq2n-raPEQz1mVg&#61;&#61;" href="https://www.thoughtco.com/white-oak-tree-overview-1343202" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="1">white oak</a>, is classified as moderately to very resistant to decay. It is used for railroad ties, lathing, siding, planks, construction timbers, mine timbers, trim molding, stair risers and treads, flooring (its highest volume finished products), fenceposts, pulp, veneer, particle boards, and fuel.</p>Forestryimages.org provides several images of parts of post. The tree is a hardwood and the lineal taxonomy is Magnoliopsida &gt; Fagales &gt; Fagaceae &gt; Quercus stellata. Due to varying leaf shapes and acorn sizes, several varieties of post oak have been recognized-sand post oak (Q. stellata var. margaretta (Ashe) Sarg.), and Delta post oak (Quercus stellata var. paludosa Sarg.)<p>Post oak is widespread in the eastern and central United States from southeastern Massachusetts, Rhode Island, southern Connecticut, and extreme southeastern New York; south to central Florida; and west to southeastern Kansas, western Oklahoma, and central Texas. In the Midwest, it grows as far north as southeastern Iowa, central Illinois, and southern Indiana. It is an abundant tree in coastal plains and the Piedmont and extends into the lower slopes of the Appalachian Mountains.</p>Leaf: Alternate, simple, oblong, 6 to 10 inches long, with 5 lobes, the two middle lobes are distinctly square, resulting in an overall cruciform appearance, thickened texture; green above with scattered stellate pubescence, pubescent and paler below.<p>Twig: Gray or tawny-tomentose and dotted with numerous lenticels; multiple terminal buds are short, blunt, orange-brown, somewhat pubescent, short, thread-like stipules may be present.</p>In general, small post oaks are top-killed by low-severity fire, and more severe fires top-kill larger trees and may kill rootstocks as well.
