In July 1794, Andre Michaux collected the type
specimen of Michaux's sumac (Rhus michauxii),
a Federally listed endangered species, in Mecklenburg County, North
Carolina, where the species was apparently later extirpated.
In November 2001, students in Dr. Barden's Conservation Biology lab
re-introduced the plant to the county at a prairie restoration at Latta Plantation Park.

Research Interests
Schweinitz's sunflower (Helianthus schweinitzii), a Federally listed endangered
species, occurs only within 100 km of Charlotte,
NC. We are using reciprocal
transplants, long-term monitoring, and habitat restoration to learn why the
species is rare and what must be done to increase its populations. We have
learned that the sunflower was one of many prairie species that once
inhabited Piedmont prairies east of the Appalachian
Mountains. We are currently restoring and monitoring three
prairie sites near Charlotte
as part of the management of the sunflower. We are also studying the ecology
and conservation of Michaux's sumac (Rhus michauxii),
a very rare dwarf shrub that occurs only in Virginia, North and South Carolina, and Georgia.
