Graduate student approved to core trees at old dam site to study impacts on carbon cycling
Summary
Katieanne Peterson, a graduate student at the University of Illinois Urbana-Champaign, received unanimous committee approval to take tree cores and soil samples at the old dam site to measure how dam removal affects tree growth and carbon capture; she will provide a report to the committee after lab analysis.
The Token Creek Conservancy Committee unanimously approved a research proposal from graduate student Katieanne Peterson to study how removal of the old dam affects tree growth and carbon cycling.
Peterson, a first-year graduate student at the University of Illinois Urbana-Champaign, told the committee she will measure tree diameters and heights, take increment cores for ring-width analysis and collect soil samples. She said coring is an injury that will not cause tree death and that she will allow the trees to respond to the small wounds on their own.
Field sampling will take place over three days and will include locations up to 100 meters upstream and downstream from the dam site. Peterson said she has sampled two other dam sites and will return to her lab for data preparation and analysis; she will provide a written report to the committee when the work is complete. Peggy McCallen moved approval; Holly Anderson seconded and the motion carried unanimously.
The committee did not place additional restrictions on the study in the meeting record; members approved the project as consistent with the committee mission and requested the final report be shared with the committee.
