A warming climate means that hardiness zones are shifting northwards. However, warmer mean temperatures during winter are also associated with increasing variability. Also, Minnesota will still have shorter winter daylengths and lower sun angle than areas further south, so that extreme winter minimum temperatures will not warm up as fast mean winter temperatures. Caution is needed in decisions regarding planting of new long-lived woody species that originate from areas south of Minnesota. We will review potential neonative trees species that are likely to be successful in Minnesota with a warmer climate.
