Eastern hemlock, Tsuga canadensis, is a keystone species native to eastern North America. However, since 2013 it has faced a significant decline at Harvard Forest due to the invasive insect, hemlock woolly adelgid, Adelges tsugae. Hemlock decline is associated with canopy loss, which thus alters its cool, damp microclimate. This leads to increased soil temperature which can affect soil decomposition rates, soil moisture, and rhizosphere dynamics. At Harvard Forest, a healthy and unhealthy stand has been identified on the Prospect Hill tract. One potential driver of different eastern hemlock health statuses is the role of root exudate quantities within the different hemlock stands. Root exudates are active compounds that help recruit beneficial microbiota. The stands also have differing bedrock, which could have weathered and developed into different soil types. Soil type influences the movement of ions in the soil. Therefore, the differences in soil type can lead to a difference in exudation and thus health response at the stands. Four mature and four young eastern hemlock trees were selected from both stands. Exudate samples were collected from the fine roots of each tree and were analyzed using total organic carbon analysis. Results from this data were analyzed in RStudio alongside other soil health measures. We hypothesized: (1) The healthy hemlocks will have more total exudates because the healthier hemlocks have a thick canopy which will result in greater photosynthesis and more photosynthetic carbon inputs to the soil through exudation. (2) The healthy stand will have a higher percentage of clay and with it, greater total exudates to potentially access cations and metals stored on the clay surfaces. (3) The younger eastern hemlock have fewer total exudates than mature eastern hemlock due to higher previously reported mortality rates.
