Multitemporal floristic and phenological (flowering) analysis of the shores of Lake Issaqueena, South Carolina
The floristic and phenological(flowering)study of Lake Issaqueena in Pickens County,SC,conducted by William Pamplin in 1970-1971 was reinvestigated in 2011-2012 using the Carolina Vegetative Survey(CVS)natural community sampling methods and photo documentation using a GPS enabled camera to determine floristic and phenological changes for this site during the forty years separating these twostudies.Phenological events(flowering)were recorded via photographs taken by a GPS enabled camera on a monthly basis.Photographs were downloaded and organized by sampling date in Picasa 3 web albums and stored in a project Google website.Plants were identified using expert knowledge,existing keys and the USDA plant database.Precipitation in 1970,2011 and 2012 was below the long-term average and this combined with higher than average air temperature impacted drought severity in the area.Comparison of phenologies indicated 269 plant species blooming in 1970-1971 compared to 203 plant species blooming in 2011-2012 and 149 common plants blooming in both study periods. The blooming period was 11 months in 2011-2012 compared to 8 months in 1970-1971. Majority of plants were blooming earlier and longer in 2011-2012 than in 1970-1971. There appears to be a phenological shift in blooming dates, but it is unclear whether it is due to climatic variation or other environmental changes in the area.
