Endemic to granite outcrops in Georgia. Despite intensive surveys only 7 small populations are known to be surviving, and these are vulnerable to habitat destruction, especially from quarrying. 3 populations have been lost since the species was first discovered in 1976.
Destruction of habitat from quarrying activities (has destroyed 9% of total population)
Heavy recreational use (trail bicycles, ORV traffic, littering, vandalism, fire building)
Eutrophication resulting from conversion of habitat to pasture (cattle w

Van De Genachte (1996) Studied the conservation genetics of the granite outcrop quillworts Isoetes melanospora and Isoetes tegetiformans for a Masters Thesis at University of Georgia. A summary of this work can be seen in Musselman (2001).
Population at Heggies Rock Preserve is owned by TNC, and has been monitored between 1985 and 1989. Some recovery from past vehicular traffic has been reported at this site (USFWS 1993).
Plants exist in cultivation at the North Carolina Botanical Garden and at the Atlanta Botanic Garden (USFWS 1993)
Protect current populations through land acquisition or by the negotiation of management agreements with private owners
Continue population monitoring
Assess the potential for reintroduction or habitat restoration efforts
Establish protocol for germination, and for maintenance of plants in cultivation.
