The Leaf Pack Network is an initiative of Stroud™ Water Research Center. The Stroud Center seeks to advance knowledge and stewardship of freshwater systems through global research, education, and watershed restoration.
Fall is a great time to do a leaf pack experiment — but not the only time! If you can’t do an experiment in the fall you can still collect and dry your leaves and then assemble and deploy your leaf packs later. Macroinvertebrates are hungry year-round! You’ll need 30 grams of leaves for each leaf pack and we recommend making three leaf packs for each experiment. You may pick leaves off...[Read More]

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.
