Estimating carbon stock of live trees located on the main campus of the University of Georgia.

Abstract

We developed a case study for estimating carbon stock (stored and annually sequestered) in aboveground and belowground portions of all the live trees located on the main campus of the University of Georgia. We recorded species, diameter at breast height, and height of trees located between East Broad Street and Carlton Street (north-south direction) and East Campus Road and Lumpkin Street (east-west direction) covering an area of 94.1 hectares. We used i-Tree Eco V6 for estimating carbon stock. There are 6,915 trees in the study area, out of which 73.0 percent (5,049 trees), 32.3 percent (2,236 trees), and 0.7 percent (50 trees) are native, understory, and invasive, respectively. The total carbon stored in trees is 3,450.4 t (SD = 65), and the annual sequestration rate is about 65 t. The University of Georgia should adopt a multifaceted approach for offsetting or reducing the overall carbon emissions, as annual sequestered carbon in measured trees is only 0.11 percent of the total carbon emitted by the university in 2018. This study highlights the role of trees in meeting the carbon reduction challenges faced by colleges and universities across the United States and beyond, and contextualizes the role of green spaces in general, and trees, in particular toward the ongoing movement of sustainable universities and campuses worldwide.
