The Leaf Pack Network® (LPN) is a network of teachers and students investigating their local stream ecosystems. The investigation uses the Leaf Pack Experiment Kit from the LaMotte Company. After conducting their own leaf pack experiment, schools share data through the network. These data shed light on the important connection between streamside forests and the ecology of rivers and streams.
The Leaf Pack experiment involves creating an artificial leaf pack (dry leaves in a mesh bag), placing it in the stream for three to four weeks, examining the packs in the classroom and discovering different types of aquatic insects that are used as indicators of stream health.
