Betula alleghaniensis
Hardwood–conifer mixed forests occur in a transition zone between lowland conifer and northern hardwood forests. The ground is less rocky than in the lowland conifer forests and thus supports more vegetation. Trees include red spruce, balsam fir, eastern hemlock ("Tsuga canadensis"), red maple ("Acer rubrum"), and yellow birch ("Betula alleghaniensis"). The understory vegetation is abundant, with witchhobble ("Viburnum lantanoides"), honeysuckle ("Lonicera" spp.), and striped maple ("Acer pensylvanicum"). The herbaceous layer include common wood sorrel ("Oxalis" spp.), bunchberry ("Cornus canadensis"), yellow clintonia ("Clintonia borealis"), ferns, and mosses.
