Park Species Detail: Hobson, 1998: A single individual of the state rare mountain camelia was documented in 1989 . . . but this individual is suspected to have died since no additional shrubs have been found at this site. The previously documented occurrence of this plant was reverified, but only one snag wa located. Element occurrence rank = D = poor. Threats to the quality of the site for rare plants arise from invasive alien lant species, particularly eulalia that is especially abundant in the ravine bottoms. Clark and Rafkind (1997) provide additional information on threats to the occurrences of bog twayblade, mountain camelia./ Townsend, 2005: global rank, G4; state rank, S2 = Imperiled -- At high risk of extirpation from the state due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors./Ludwig, 1993: Stewartia ovata . . . is found on a ridge growing amid a dense shrub layer of Kalmia latifolia and Myrica cerifera. Monitor . . . to determine degree of threat from the Eulalia viminea population. If competition with the exotic is a threat, implement control measures to protect the population., Park Species Data Source: Ludwig et al, 1993a-Colonial Parkway/Jamestown Unit/Yorktown Unit;Hobson, 1998-Yorktown Unit/ Cheatham and Wormley Pond Drainages;Clark, 1998-Colonial Parkway/Jamestown Unit/Yorktown Unit;
