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.
Net-spinning caddisflies build nets to trap their food. But did you know that these nets also hold rocks together in streams?
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.
