Summer Research 2019 has just concluded! Thanks so much to Sean Ahn, Evan Hill, Amelia Richardson, Sam Russo, and Wesley Smith for your amazing work all summer. We had a very productive six weeks of research, investigating gas exchange in trees on the Earlham Plantation and mapping the biodiversity of the Earlham Backcampus Prairie. We identified over 100 plant species and found that native plant richness was much higher and invasive richness was much lower in the fire-maintained prairie than mowed old-field community. Planted trees varied in their instantaneous carbon uptake and water-use efficiency. This pilot study could not draw strong conclusions about which species are better as a carbon sink, but it demonstrates the potential for the Earlham plantation to serve as an important carbon sink for the campus community.
