About

Quercus incana is a species of oak known by the common names bluejack oak, upland willow oak, sandjack oak, and cinnamon oak. It is native to the Atlantic Plain and Gulf Coastal Plain of the United States, from Virginia around Florida to Texas and inland to Oklahoma and Arkansas.

Where it grows

Quercus incana often grows in longleaf pine (Pinus palustris) ecosystems, where it shares the understory with turkey oak (Q. laevis) and wiregrass (Aristida stricta). In the Big Thicket of Texas it codominates with post oak (Q. stellata) and a number of pines. The oak can be found on sandy soils. It grows downslope from ridgetops, where the soils are finer and less dry than the tops of the ridges. It is well adapted to wildfire and grows in habitat where fire is common and often required, such as longleaf pine ecosystems. The oak does not tolerate dense shade and requires fire to remove taller, more robust oaks that would otherwise outcompete it.

Uses

The wood of Q. incana is hard and strong, but the trees are usually too small to be useful except as fuel or posts.
