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.

In natural and artificial leaf packs, after a few weeks of submersion, the leaves become slimy with the colonization of fungus and bacteria and, in time, are colonized by macroinvertebrates. Leaf packs provide important habitat for macroinvertebrates in healthy streams.

Leaf Pack Network Program Materials List. The Leaf Pack Stream Ecology Kit contains everything you need to perform a leaf pack project with a group. Use the following lists if you choose to purchase materials independently of the kit or if you need to replenish your kit materials.

The Leaf Pack Network® is designed to enhance understanding of stream ecosystems and to demonstrate the importance of streamside forests. Historically streams, and the life in those streams, evolved and developed under forested conditions.

Prepare two replicate leaf packs representing each of the three leaf types into the stream (two oak leaf packs, two willow leaf packs and two maple leaf packs) for a total of six leaf packs. Is A Control Leaf Pack Necessary?

leaf packs have layers of leaves, typically trapped against a rock, with stream water fl owing rapidly over them, which keeps the leaves in place. some time and
