Some species in Mesic Hardwood Forests are projected to decline across northern Minnesota by the end of the century (quaking aspen, paper birch).

Multiple forest impact models tend to agree that these species are more likely to decline in suitable habitat and biomass across a range of climate scenarios by the end of the century. NPC Class MHn44 (Northern Wet-Mesic Boreal Hardwood-Conifer Forest) may be particularly vulnerable because this class contains boreal species such as quaking aspen, balsam fir, and paper birch.
