Spring isn’t the only time of year that Mason Farm Biological Reserve is worth a scenic stroll! Join naturalist Ed Harrison for an in-depth tour of the “old farm trail” that travels through some 260 years of cultural and natural history. Ed will point out early fall wildflowers and others as well as discuss the many positive effects of the Garden’s intense management for both field and forest on the Reserve. Meet at the ncbg Visitor Parking Lot gazebo. Fee: $10 ($5 ncbg members).
