Many dominant tree species in aspen-birch forests are expected to decline across northern Michigan by the end of the century (quaking aspen, balsam poplar, and paper birch).

Quaking aspen, balsam poplar, and paper birch are boreal species near their southern range limits in Michigan. 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. These species exist on a wide range of soils and landforms, and this forest type is a management priority for many landowners.
