Longleaf Pine Woodlands
Xeric-Mesic, Sandy Woodlands and Scrub
General Description Members of this habitat include species of oaks (Quercus) that are restricted to sand ridge habitats in the Coastal Plain, along with a set of the herbivores that are strongly associated with them.

Turkey Oak (Quercus laevis) is adapted to deep sands and highly xeric soil conditions. The other oaks, however, are more associated with pockets of clay or loammy soils imbedded in the sands and with somewhat more mesic soil moisture. All are adapted to frequent wild fires. The root systems and seeds of the plants survive below ground and resprout following a burn. The animal members of this habitat probably do not survive a fire directly, but instead rely on re-colonization from unburned refugia to maintain their populations within these habitats.

This habitat intersects the General Longleaf Pine habitat, the Sand Ridge Herb and Grassland habitat, as well as the habitats defined by more generalized oaks, pines, and their associated animal species, and the species associated primarily with the sandy substrates themselves.

Distribution Map
Distribution The range map shows that this habitat is concentrated in the Fall-line Sandhills and Outer Coastal Plain, both areas with significant amounts of sandy woodlands and scrub. No county, however, has the full set of species identified for this habitat. Moore County has the most recorded species at 18, but that is ten short of the total number expected for this habitat. The explanation is probably that these habitats were naturally patchy in distribution and have become more and more fragmented due to conversion to human uses and to the suppression of wildfires. Once lost from a given site (or county), it is becoming increasingly difficult for species to recolonize those affected areas from areas outside.
