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.
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.
In October, Stroud Water Research Center hosted 17 people from Central and South America for an intense 5-day workshop. Participants — who included educators, conservation professionals, and government agency representatives — took the Spanish version of the Leaf Pack Network manual back to their countries.
