PLANTS IN THE GILLS CREEK WATERSHED!

Our plant inventory shows the diversity of plants and habitat in the watershed.

This list began with a floral inventory of the Gills Creek watershed from field observations, herbarium research, and expert reports. We invite residents of the watershed to get involved and relay your observations to us for inclusion in our list.

Resources for help with identification are listed at the end of this document.

The list includes naturally occurring plants and plants that have escaped cultivation.

NINV – Native invasive, causing problems in natural areas outside its native range.

For a list of the most troublesome invasive species of plants and animals and links for identification and removal, see our Invasive Species in the Watershed page.
(location)
SSP - Sesquicentennial State Park is the site best representing the sandhills.
JLJ - Jackson/Little Jackson Creek
AL - Arcadia Lakes
FALK - Forest Acres/Lake Katharine
SRH - Shandon/Rosewood/Heathwood
OFP - Owens Field Park and Shandon lots are disturbed areas that people have cleared, so the species found in these locations are commonly occurring weeds.
HSC - Hammond South Campus and Buchanan St. (off Beltline Rd.) represent mixed sandy-silt floodplain with upland slopes and mixed pine-hardwood forests.
SBW - S. Beltline locations (Hickory and Mikell streets) and Bluff Rd. represent coastal floodplains.
FJ - Fort Jackson
SBH - South Beltline/Hamptons/Humane Lane are a mixture of the Gills Creek floodplain and upland slopes.
ABR - Arthurtown/Bluff Road
CF - Congaree Floodplain
if no location is noted, plant is widely observed in the watershed

AWFI - Austin Williams' Floral Inventory. This project was conducted from fall 2014 through spring 2016 to satisfy the Honors Thesis requirement in biology from the University of South Carolina. The final product was a list of plants that are known to presently or historically exist in the watershed. The paper is available at Scholar's Commons. Although the paper was the basis for our inventory, it is only cited when it notes unusual or rare plants.
USCH - University of South Carolina A. C. Moore Herbarium

LRK - Lewis Kirk
