On Sunday, September 16 from 10 – 2, hike with Patricia Swain and the New England Wild Flower Society through Mt. Watatic Reservation’s open summits, the adjoining spruce and northern hardwoods forests, and several types of transition communities between them. The views of the multiple community types should provide near-peak fall color, great for differentiating species and for our enjoyment. Habitat: northern forests including spruce, fir, northern hardwoods, and rocky summits, known for red spruce forest, spruce and northern hardwood forests, acid rocky summits, open oak forest, ridgetop heathland, blueberries, and huckleberry barrens. Difficulty: Moderate/Difficult. $38 for NEWFS members, $46 for nonmembers. Register at www.newenglandwild.org.
