Description
Summary:Linking historic herbarium collections with current geospatial temporal floristic and phenological data is crucial for environmental change research and education. 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 two studies. 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. 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 plants blooming in 2011-2012, and 149 common plant species blooming in both study periods. The blooming period was 11 months in 2011-2012 compared to 8 months in 1970-1971. A majority of plants were blooming earlier and longer in 2011-2012 than in 1970-1971. Repeat photography and data storage using website have a great potential to enhance phenological research by linking it to historical herbarium collections.
