Cool Trees: Surviving Cold Temperatures
University Outreach Publication
Trees are found all over the globe in a variety of climates. One of the most limiting climatic constraints on tree growth is the lowest sustained temperature which the tree must endure and survive. In addition to absolute low temperatures, climate can damage trees by too quick of temperature change preventing appropriate tree reactions. Temperatures too low and changing too fast or too slow kills trees. A good example of cold constraining tree growth and survival can be seen as the tree growth line on high mountain sides which are associated with low temperatures, wind stress, and water availability problems. Trees are not usually found in areas or at altitudes where sustained temperatures in the dormant season fall below -22°F. For trees around the world, they must adjust to cold temperatures or die.
