Now I want to share a wonderful rescue story with you. Charleston was blessed to land the second Boeing Dreamliner manufacturing plant last fall – a real economic boost for our community. For me, the excitement was tempered with dread because I knew that the only inland Charleston County population of southern sugar maple, see photo above (Acer barbatum), quite rare on the Coastal Plain, was located on the Boeing site, which is near the Charleston air- port. I first discovered this population more than 10 years ago, when I stopped on the roadside to photograph the uncommon Elliott’s aster (Symphyotrichum elliotii). I turned my head and spotted the maple. I stared with disbelief – this is not an inland species on the outer Coastal Plain. We see it on salt marsh shell mounds. But there it was, and I was so thrilled! It was late fall, and my quick dash into the woods revealed little. This is a habitat that blossoms in the spring. I tried for many years to gain access to the site in the spring, but was always turned away, and I was never even able to document the maple due to post 9/11 security. I never lost my intense curiosity to know what else might be in there, though, and when the Boeing announcement was made, I was able to contact them, assisted by an interested Post and Courier reporter who later wrote 2 fantastic articles on the rescue project. To my utter delight, Boeing granted access. We had to move quickly, though! Almost from one day to the next, I was given permission to take my plant taxonomy class to the site. We roamed Jean Everett, PhD College of Charleston Biology Department Boeing Site Plant Rescues Greetings, fellow SCNPS mem- bers. In the last issue I gave some highlights of the 2010 symposium in the Low Country. Our 2011 Symposium is planned for Saturday, May 14, 2011 in Rock Hill at the Museum of York County. Details are still being worked out, but we will have a one- day event, with several speakers in the morning, starting at 10:00, followed by field trips and workshop sessions in the afternoon. Field trips will include the rocky shoals spider lilies site. The York County region is home to some very interesting native plant communities, including remnant piedmont prairies. The Museum has been a long-term partner with the Piedmont Chapter. Over the last 5 years, the MYCO and the Piedmont Chapter have planned native plant sales, field trips and vari- ous programs that focused on native plants and communities, such as the piedmont prairies. The MYCO features a rain garden that was installed at the 2007 Symposium and a Carolina Fence Garden that is maintained by SCNPS members. So, please save this date on your calendar, and look for regular updates on the SCNPS list-serve and website, and in newsletters. Jeff Beacham, President Fall 2010.indd 1 9/24/10 9:15 AM
