Global Rank: G2 - Imperiled
Legal Status: Federally Endangered
Family: Rosaceae
State: NC, SC
Nature Serve ID: 138698
Lifeform: Forb/herb
Date Inducted in National Collection: 04/01/1990

Description:

Endemic to two counties of the Carolinas, this aquatic herb has a severely threatened habitat. The mountain bogs in which Sagittaria fasciculata occurs have been drained for residential development and pasture. In the few remaining suitable sites, the population growth of nearby cities presents the continual threat of disturbance. Several other rare plants share the restricted habitat of Sagittaria fasciculata, making the protection of these areas a top priority.

Where is Bunched Arrowhead (Sagittaria fasciculata) located in the wild?

Habitat:

Mountain bogs, partially shaded seeps with constant but moderate water flow, where it typically inhabits a narrow band at the bluff-floodplain ecotone (USFWS 1983).

Distribution:

Henderson County, North Carolina and Greenville County, South Carolina (USFWS 1983).

States & Provinces:

Bunched Arrowhead can be found in North Carolina, South Carolina

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. ?

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 (USFWS 1983)
