"It was so completely overgrown with trees and vines that I couldn't even see the 7-foot-long sign with bright yellow lettering marking the site that was only a few feet from the road," Treuer said. "I knew we needed to come up with some really robust metrics to quantify exactly what was happening and to back up this eye-test, which was showing up at this place and realizing visually how stunning the difference was between fertilized and unfertilized areas."
Treuer studied the area with Jonathan Choi, who, at the time, was a senior studying ecology and evolutionary biology at Princeton. Choi turned the project into his senior thesis.
"The site was more impressive in person than I could've imagined," Choi said. "While I would walk over exposed rock and dead grass in the nearby fields, I'd have to climb through undergrowth and cut paths through walls of vines in the orange peel site itself."
