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.
