Hubbard Brook Streamflow Response to Deforestation

Back to Search Results

This teaching activity explores what the short- and long-term effects of a whole-watershed deforestation experiment are on streamflow. Students can use an MS Excel file or hard copy of data to graph short- and long-term streamflow response to a whole-watershed manipulation. Students can then compare results to baseline data, draw conclusions about hypotheses, and consider implications of long-term research.

Pedagogical Use Description	This activity compares short- and long-term data collected after a whole-watershed experiment conducted in HBEF Watershed 2 in 1965. Because data collected in the years immediately following the experiment suggest a different response than data collected twenty years later, this activity would be a useful addition to a discussion of the importance of long-term experiments and data collection in ecological research. NOTE: Data can be graphed easily with Excel or by hand.
