In this activity, students work with data collected during 15 years as part of a long-term research project at Harvard Forest. Students analyze the data to address the question, "How have stands of pine and hardwood forest responded to long-term nitrogen fertilization?" Students address the question using data on several ecosystem characteristics and processes: net primary productivity, tree photosynthetic capacity, soil respiration, and soil microbial biomass.
