Over the past decade, several deer and moose exclosures have been built at the Harvard Forest to study the effect of ungulate browsing on tree regeneration, species diversity, and composition. In 2018, we continued the processing of the soil samples collected in 2017 at the four sites with exclosures located within the limits of the Harvard Forest; three on the Prospect Hill tract and one on the Tom’s Swamp tract
Samples are currently being processed at Boston University. Root biomass has been measured for all samples. Soil carbon and nitrogen content are in the process of being determined on each sample. Root carbon and nitrogen content will also be measured.
