The tract is almost completely wooded. DEC identifies five distinct forest communities within the Slide Wilderness: three subtypes of the boreal forest found at higher elevations in the Catskills ("mountain fir", "mountain spruce-fir" and "spruce-fir rocky summit"), hemlock-northern hardwood forest and beech-maple mesic forest northern hardwoods, such as sugar maple, beech and yellow birch, are the most predominant, with associate species such as black cherry, white ash, red maple, basswood, big-tooth aspen and red oak can be found at some locations. White pine and hemlock also carve out some groves of their own, particularly in areas closer to streams.
