Nature never deceives us; it is always we who deceive ourselves.                         - Jean Jacques Rousseau

Had Rousseau walked in the 18th-century Alleghenies, he would have observed a substantially different natural world than the one that we see today. Old-growth forests, filled with mighty chestnut, hemlock and beech trees, dominated the ridges. A wondrous diversity of plants provided food and other essentials of life.

Over the ensuing centuries, old-growth forests were cut, blight decimated the chestnuts, and species such as Japanese knotweed and multiflora rose were introduced, crowding out native plants.

Natural Biodiversity is a program committed to curtailing invasive species and restoring native plants. Learn more about our mission, our projects, and how you can help!
