Abstract: The diabase geology of North-central North Carolina supports remnants of several historically prevalent plant communities whose original characteristics must be extrapolated from their fragmented and degraded current states. This suite of vegetation types ranges from annual grass-dominated glades, through perennial grass-dominated barrens, to distinctive oak-shortleaf pine woodlands. Of these diabase-influenced vegetation types, which host a number of rare and disjunct species tracked by the NC Natural Heritage Program, the most poorly understood and speculative is the perennial grass-dominated barrens. These currently maintain a tenuous existence along roadsides, under powerlines, and on private and public lands, only a few of which are adequately protected and managed. We will provide an overview of the flora of existing sites and present preliminary results of an inventory of remnants in a 3 county study area (Durham, Granville, Orange). Using soil maps, expert knowledge, rare plant locations, and field surveys, we have complied a list of known sites and a quality ranking process by which to evaluate these sites. Further, we will discuss issues involved in the restoration, management and potential expansion of these sites for long-term protection.
