15 Years of the Leaf Pack Network®

The Leaf Pack Network helps people assess their stream’s health by performing a simple leaf pack experiment. Since the Stroud Center launched the Leaf Pack Network in late 2000, groups registered in 38 U.S. states and 11 countries have completed 671 experiments, tallying nearly 100,000 macroinvertebrates! Can you spot which states don’t have groups yet?
