NatureServe Status

Global Status: G3
Global Status Last Reviewed: 26Jan2003
Global Status Last Changed: 21Nov1985
Rounded Global Status: G3 - Vulnerable
Reasons: Coreopsis latifolia is a rare species known from the Blue Ridge Mountains, occurring in western North Carolina southward into South Carolina, northeastern Georgia and Tennessee. This composite is a species of rich, moist, deep, well-drained shaded sandy loams.
Nation: United States
National Status: N3

Other Statuses

NatureServe Global Conservation Status Factors

Range Extent Comments: Blue Ridge Mountains, from western North Carolina southward into South Carolina and northeastern Georgia (Kral). Also occurs in Tennessee (Kartesz and Meacham 1999).

Number of Occurrences: 21 - 80

Population Size Comments: Rare across its range, with highest abundance in North Carolina. In Georgia most populations consist of a few clumps. Tom Patrick has observed it mostly along roadsides but thinks there might be more in remote hardwood slopes where concentrated searches have not been undertaken, although given how conspicuous the plant is, other botanists working in the north Georgia mountains should have found it more frequently. On the other hand it may be overlooked because it somewhat resembles other yellow composites with broad and thin leaves, such as Heliopsis helianthoides (Patrick, 1999).

Overall Threat Impact Comments: Coreopsis latifolia occurs over a somewhat narrow range in restricted habitats, (rich, mesic forests) making it especially vulnerable to land-use conversion, habitat fragmentation, and forest management practices. Threatened by vacation home development (view lots) in some areas on private land; logging or timber sales in mid-high elevation oak stands could impact the species (Southern Appalachian Species Viability Project 2002). Probably under no distinct threat providing forestry practices remain about the same on national forests within the Blue Ridge; selective cutting of hardwoods probably is beneficial to this light-gap dependent species (Patrick, 1999).

Short-term Trend: Relatively Stable (<=10% change)
Short-term Trend Comments: Considered "stable" at the Southest Heritage Conference (November 1994).

Ecology & Life History
Help
Habitat Comments: Mesic forests, especially over mafic rocks such as amphibolite or hornblende gneiss. Rich, hardwood forested mountain coves and slopes; well-drained, shady sandy loams. Generally not seen above 1200 m. Invariably in or at the edges of open or dense forest. The site is often rocky, the deep soil around or pocketed in a jumble of acidic rock (Kral).
