Description
A description of Quercus incana is provided in The Flora of North America.
Distribution
Ecology
Habitat
Q. incana has been found in turkey oak-longleaf pine stands, sand dunes, sand pine scrub, longleaf pine-wiregrass ridges, slashpine flatwoods, dry pine barrens, upland woods, and evergreen oak scrub.[1] It is also found in disturbed areas including along roadsides, clear cut longleaf pine forests, and burned pinewoods.[1]
Associated species: Q. myrtifolia, Quercus marilandica, Opuntia humifusa, Stillingia sylvatica, Tephrosia virginiana, and Quercus-Ilex.[1][2][3][4]
Quercus incana is restricted to native groundcover with a statistical affinity in upland pinelands of South Georgia.[5]
Q. incana has shown regrowth in reestablished longleaf pine woodlands that were disturbed by agriculture in South Carolina, making it a post-agricultural woodland indicator species.[6] It also increased its density in response to disturbance by roller chopping in west Florida sandhills.[7]
This species became absent in response to military training in west Georgia longleaf pine forests.[8] Q. incana reduced its frequency and density in response to roller chopping in northwest Florida sandhills.[9] It also became absent and decreased its occurrence in response to agriculture in north Florida pinelands.[5] It has shown resistance to regrowth in reestablished habitats that were disturbed by these activities.
It does not respond to soil disturbance by clearcutting and chopping in north Florida flatwoods forests.[10]
Quercus incana is frequent and abundant in the Panhandle Xeric Sandhills, North Florida Subxeric Sandhills, and Clayhill Longleaf Woodlands community types as described in Carr et al. (2010).[11]
Phenology
Q. incana has been observed flowering in March and April.[12]
Seed dispersal
This species is thought to be dispersed by gravity.[13]
Fire ecology
Populations of Quercus incana have been known to persist through repeated annual burning.[14]
Herbivory and toxicology
Q. incana has been observed to host treehoppers such as Ophiderma pubescens (family Membracidae).[15]
