Description
Q. margarettae is a perennial shrub/tree of the Fagaceae family native to North America.[2]
Distribution
Q. margarettae is found in the southeastern corner of the United States from Texas to Virginia.[2]
Ecology
Habitat
Q. margarettae proliferates in sandhills, typically in slightly loamy or clayey soils, not usual in the deepest and most xeric sands.[1] Specimens have been collected from mixed woodland, longleaf pine-scrub oak, sandpine flatwoods with sandy soil, hardwood hammock, planted slash pine on sand ridge, longleaf pine wiregrass scrub oak ridge, hardwood stand, beach ridge, sand pine scrub, and loamy sand of xeric flatwoods.[3]
Q. maragarettae reduced its occurrence in response to soil disturbance by agriculture in South Carolina longleaf woodlands.[4] It has shown resistance to regrowth in reestablished longleaf woodlands that were disturbed by agriculture in South Carolina, making it a possible indicator species for remnant woodlands.[5]
Q. margarettae does not respond to soil disturbance by clearcutting and chopping in north Florida flatwoods forests.[6]
Quercus margarettae 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).[7]
Phenology
Q. margarettae has been observed to flower March through June.[8]
Seed dispersal
This species is thought to be dispersed by gravity.[9]
Fire ecology
Populations of Quercus margarettae have been known to persist through repeated annual burns.[10][11]
