Piedmont: Field trip to Blackjacks Oak Savanna

October 21, 2017 @ 10:30 am - 5:00 pm

In celebration of South Carolina’s Native Plant Week (Oct 16 – 20) the Piedmont Chapter of the SC Native Plant Society is hosting a field trip to some uniquely interesting natural native plant communities in our area.

South Carolina has a lot of natural diversity for a state of our size, and one of the most interesting sites is the Blackjack Oak Savanna.

The SC Dept. of Natural Resources’ Blackjack Oak Savanna is found on the edge of Rock Hill, in an area of basic rock geology. These basic rocks break down into high calcium, high magnesium soils with near neutral pH. These soils contain a clay type that swells when wet, and shrinks and cracks when dry. This shrinking and swelling is damaging to tree roots. Blackjack oak (Quercus marilandica), another short-statured tree, is more tolerant of these conditions than most other trees. Again, short, thinly spaced trees allow maintenance of native grasses and wildflowers. These two sites contain a large number of prairie-type grasses and wildflowers (some quite rare in our State) that persist naturally, and are unique in the largely forested Piedmont of SC.

On Saturday, October 21 the Piedmont group will lead a trip to the Blackjacks site. The 10:00 meeting spot in Rock Hill is at the Blackjack Oaks Heritage Preserve parking area off Blackmon Rd. There is limited parking, so please carpool.
