"Life at the Bottom of the Food Chain"

Wetlands microbes are often called “the lungs of the earth.” Explore the dynamics of microbial communities in LaRivere Marsh ponds. Join microbiologist Wayne Lanier, PhD for a brief presentation in the Visitor Center; then a microscope hike to LaRiviere Marsh where we will view the most ancient creatures on earth. See how they produce the oxygen we breathe and take up the carbon dioxide we produce. Ages 9-90 years. Call 510-745-8695 or email vs_intern@yahooo.com for reservations.
