Endemic to a small area of the Carolinas and restricted to very specific aquatic habitat conditions, including continuous seepage. ?There are several on-going threats including land conversion, negative hydrological changes and exotic species. ?
Habitat destruction (drainage of seeps for residential/commercial development)
Disturbance by livestock
Competition with other species for space, nutrients (encroachment of woody spp., shading by exotic weeds)
Change in water flow rates
7 element occurrences in North Carolina, 26 element occurrences in South Carolina (USFWS 1983).
Newberry (1991) evaluated the effect of artificial reduction of interspecific competition on growth and reproduction, and performed demographic and longevity studies. Results showed that Sagittaria fasciculata is sensitive to changes in flow rates and silt deposition. Interspecific competition for light, nutrients and space was also found to be a major factor affecting growth and survival.
Plants have been successfully grown by tissue culture by Valerie Pence at the Cincinnati Zoo and Botanic Gardens.
The South Carolina Heritage Trust has begun efforts to protect a number of populations through agreements with landowners. In cooperation with Duke Power Company, they have also conducted experimental management of populations in a power line right-of-way.
The Nature Conservancy of North Carolina and Southern Railway are cooperatively managing sites in NC, and the Nature Conservancy and General Electric Company have signed a similar management agreement.
The North Carolina Plant Protection Program has conducted one site restoration and reintroduction in a historical mountain bog
Research on reproductive biology
Propagation and reintroduction studies
Monitor existing populations, search for additional populations or sites suitable for reintroduction
Weeding as a management strategy to reduce competition
Germination protocol needed.
