Some tree species in upland spruce-fir forests may be more likely to persist across northern Michigan by the end of the century (red maple, quaking aspen, and white pine).

These species all tolerate a fairly wide range of conditions. Multiple forest impact models tend to agree that these species are more likely to increase or remain stable in suitable habitat and biomass under a mild climate scenario, but these species are all expected to fare worse under a hotter, drier future climate scenario.
