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.

估算位于乔治亚大学主校区的活树的碳储量

我们开发了一个案例研究，用于估算位于佐治亚大学主校区的所有活树的地上和地下部分的碳储量（存储和每年封存）。我们记录了物种，胸部高度的直径以及位于东布罗德街和卡尔顿街之间（南北方向）以及东校园路和卢普金街之间（东面和西方向）之间树木的高度，树木的面积为94.1公顷。我们使用i-Tree Eco V6估算碳储量。研究区域中有6,915棵树，其中分别是原生树种，林下树种和入侵树种的73.0％（5,049棵树），32.3％（2,236棵树）和0.7％（50棵树）。树木中储存的碳总量为3,450.4吨（标准差= 65），年封存率约为65吨。
