Jack pine forests in northern Wisconsin and western Upper Michigan may be tolerant of increased moisture stress due to climate change.

Jack pine forests can thrive on droughty, nutrient-poor sites. These traits may allow jack pine forests to tolerate a moderate amount of moisture stress and disturbance due to climate change. Although some current jack pine sites may become too hot or dry in the future, other sites currently dominated by red pine, white pine, or other species may become more suitable for jack pine. Jack pine seedlings are more susceptible to drought stress than are established trees, however, and regeneration failure may occur more frequently.
