The Fundamentals of Earthworms & Waste Reduction. Registration now open Join us for this hands-on workshop to explore the biology of this extremely important yet under-appreciated organism. Find out how they can reduce the amount of land used for sanitary landfills and can clean up contaminants in our soil. Learn why an earthworm's life cycle and bodily functions make them a gardeners' and farmers' best friend, yet a forester's foe. This workshop is sponsored by a Mansfield Twp. Recycling Grant.
