Field work at Harvard Forest
From May 2015 onward, we have been monitoring the canopy below the Hardwood Walkup Tower at Harvard Forest. This monitoring will allow us to better characterize how individual trees and the whole canopy cycle and store carbon through the growing season from May-October. Sometimes you take bike to get samples, sometimes you take a canopy lift called "Bucky". Hualei Yang, a PhD student, is pictured helping in the canopy lift, and Jonathan Michelsen, an undergraduate from University of Chicago, is manning the leaf-level fluorometer.
