Leaves that fall into streams form natural leaf packs that provide food for aquatic organisms. Participants create artificial leaf packs and place them in a stream for three to four weeks. The leaf packs are retrieved from the stream and examined in the classroom... ...leading to the discovery of aquatic macroinvertebrates that indicate stream health. Schools enter their data into the online Leaf Pack database to share with the public. LPN experiments teach the importance of streamside forests and promote their stewardship.

The Leaf Pack Network® (LPN) is a network of citizens, teachers, and students investigating their local stream ecosystems. Using the Leaf Pack Experiment Kit, participants:

Interested in connecting your classroom to the outdoors? Here’s how to get started!

Anyone interested in learning about riparian communities can use the resources available on the Leaf Pack Network®. Navigate the LPN website using the menu on the left, or start with these pages:

View data from a particular stream. Search by major watershed or school.

Visit our learning center to learn about watersheds, the link between trees and streams, macroinvertebrates, or data analysis.

Explore interesting resources from Stroud Water Research Center and other organizations that provide information about rivers and streams.

Slimy Leaves For Healthy Streams

A Training in the Leaf Pack Network for middle and high school teachers and environmental educators

Saturday, September 17
9:30 a.m.–3:30 p.m.
at Stroud Water Research Center

How can clumps of slimy leaves spark stream exploration? The Leaf Pack Experiment is a fun, hands-on research and outreach tool for citizens of all ages and teachers, demonstrating how our actions on land impact life in streams and water quality.

Sacramento Leaf Pack Network workshop

Leaf Pack promotes inquiry-based interdisciplinary watershed education and engages diverse audiences in conducting their own experiments, gathering relevant ecological data, exploring food webs, learning classification skills, using technology to share data, comparing data with those of other communities and applying that information to protect local watersheds.

Join us at our workshop, we’ll show you how! During this workshop participants will receive an overview of stream ecology and watershed concepts based on research done at the Stroud Water Research Center.

Taking our boots to the stream, we’ll then experience hands-on examination of leaf packs with live aquatic macroinvertebrates, including their identification and a look at the Leaf Pack Network┬« website and database.

Registration deadline is September 14!

$10 per person

At the workshop you will receive:
