Welcome to the Leaf Pack Network, an international network of people investigating their local stream ecosystems. Leaf Pack Network is part of WikiWatershed, an initiative of Stroud Water Research Center to help people advance knowledge and stewardship of fresh water.
In September 2009, Yosemite Institute began using leaf packs to study macroinvertebrates in four streams in Yosemite Valley. Students have been studying water chemistry in these streams for several years but institute staff felt that biomonitoring would provide a more accurate measurement of the health of these ecosystems.
David C. Richardson wrote in the professional journal Stormwater about Forest Grove Community School in Oregon and Mahopac High School in New York, two of the schools that are using the Leaf Pack Experiment and getting results that are making a real difference to their communities.
Charlie Graham teaches all subjects, including science, at Forest Grove Community School. He takes his job seriously and gets genuine enjoyment from watching his students connect the dots and understand their relationship to the environment. So, it’s no wonder that he is a fan of the Leaf Pack Experiment Kit.
