Mt. Airy Arboretum

Planting and rehabilitation of farmland purchased in 1911 began almost immediately. During the next 10 years, over 1,000 acres were acquired for reforestation and conservation purposes and, in later years, additional land acquisition increased the total area to its present 1,469 acres.

What was once scarred, eroded, and nearly treeless ridges and slopes has become today's lush forest which includes 700 acres reforested in hardwoods; 200 acres reforested in evergreens; 269 acres in native woodland; 170 acres of open meadows and 120 acres of arboretum development.
