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 responds positively to agricultural-based soil disturbance in South Carolina coastal plains communities.[6] It also responds positively to roller chopping in West Florida with an overall increase in density.[7] When exposed to soil disturbance by military training in West Georgia, Q. incana responds negatively by way of absence.[8] Q. incana responds negatively to soil disturbance by roller chopping in Northwest Florida sandhills.[9] 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]
