Forest Ecosystem Responses to Chronic Nitrogen Additions
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.

| Pedagogical Use Description | This activity can be used to teach students about the effects of long-term nitrogen deposition on forest ecosystems. It provides background information on nitrogen deposition and the research project that generated the data. There are complete instructions that guide students through the data analysis as well as guidelines for teachers on how the activity can be used and adapted. The activity incorporates active learning methods to engage students in their own learning process. Open-ended questions, synthesis activities and criteria for student evaluation are included. |
