GoKawiilFront Range Cities Urged to Diversify Urban Tree Species Amid Climate Stress
Experts at the Eighth Annual Tree Diversity Conference warned that Colorado's Front Range has unusually harsh growing conditions for trees—hot summers, cold winters, alkaline soil and a shortened growing season—and that climate models show these stresses intensifying, especially at higher elevations. Speakers noted that losses of ash and cottonwood trees, combined with rising heat-island effects from pavement and dense development, are weakening urban forests and leaving them more susceptible to pests and disease.
