The northern hardwood-conifer forest is found around the refuge in the mid-and upper-elevations, serving as a transition from the lower hemlock-hardwood-pine forest to the high elevation spruce-fir forest. This is the most abundant refuge habitat type. Approximately 705 acres of northern hardwood-conifer forest are present on the refuge. The northern hardwood-conifer forest is characterized by American beech, sugar maple, and yellow birch. The northern hardwood-conifer forest supports a large diversity of plant life. The most common tree types are yellow birch, eastern hemlock, American beech, white pine and red oak. The understory of the northern hardwood-conifer forest is very diverse, including striped maple, high bush blueberry, mountain laurel, and hobblebush. Ephemeral plants and other woodland wildflowers thrive in this forest type. Trillium, goldthread, wild sarsaparilla, pink lady’s slipper, wood sorrel and several ferns are found in the herbaceous layer of this forest type.
