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.

Become Empowered and Energized Learning About Your Local Watershed!

The Leaf Pack Network® is an international network of teachers, students, and citizen monitors investigating their local stream ecosystems. Following instructions in the Leaf Pack Network Manual, monitors use tree leaves and aquatic insects to determine the health of their stream and understand its ecology.

Get Involved!

Individuals participating in the Leaf Pack Network engage in the full process of conducting real research while communicating and sharing their results worldwide. The Leaf Pack Network can be easily implemented in any curriculum and fulfills many state and national science standards.
