Leaf Pack Experiments Stream Ecology Kit
Got bugs in your stream? This complete kit helps students discover the value of macroinvertebrates as living indicators of water quality. A totally reusable and flexible tool, this kit can be adapted for varying time limits, number of students, and grade levels.
Conducting a leaf pack experiment by placing artificial leaf packs in streams replicates the natural process of leaves forming packs in streams and can be an important tool for understanding the structure and function of stream macroinvertebrate communities. The basic idea is that leaf packs will become colonized by macroinvertebrates. The relative abundance and diversity of macroinvertebrates found in the leaf packs can be used as an indicator of the stream habitat quality and an indicator of water quality.
