Range Extent250-20,000 square km (about 100-8000 square miles)
Number of Occurrences21 - 80
Rank Reasons
Restricted range, regional endemic. Still relatively easy to find in appropriate habitat. Don't be swayed by number of Georgia counties (45); they are half the size of neighboring states' counties. Monotypic genus. It occurs in small numbers, usually less than 30 per population. Clear threats but probably not at critical point yet. Few protected populations.
Range Extent Comments
Pinckneya occurs from southernmost South Carolina southwestward to the Florida Panhandle (west to Okaloosa County); there is a slightly disjunct grouping in Clay, Putnam, and Marion Counties, Florida. It is also slightly disjunct to Butts County, Georgia. Historically, it occurred in Beaufort and Jasper Counties, South Carolina, at least 45 counties in Georgia, and 15 counties in Florida. Currently it is known from Jasper County, SC, and an undetermined number of counties in GA and SC. There are no proven records for Alabama.
Occurrences Comments
This species is tracked only in South Carolina, so site-specific data is scarce over the bulk of the range. In South Carolina, there are 4 current EOs. Based on the number of total counties of occurrence and the frequency with which botanists encounter it, only a broad estimate of 20-100+ can be made.
Threat Impact Comments
Conversion of habitat to pine plantations and to agriculture are the two main threats. Included in this is the construction of farm ponds and stock ponds, usually done in stream headwaters.
Ecology & Habitat

Habitat

Pinckneya occurs in and at the margins of streamheads in habitats termed streamhead pocosins, bayheads, branch bays, and seepage swamps. It also may occur in adjacent seepage bogs without associated canopy species. These communities are perennially saturated due to active seepage water which is forced to the surface by underlying clay layers. Trees typically are small to medium sized members of Nyssa, Acer, Liriodendron, Persea, Symplocos, Quercus, Liquidambar. Associates include a number of ericaceous shrubs in these genera: Ilex, Vaccinium, Clethra, Gaylussacia, Lyonia, Leucothoe, Rhododendron, Viburnum, Toxicodendron, Myrica.
