Examples of maladapted trees experiencing stress from abiotic factors • Adverse environmental factors add up to cause vigor problems. • No pests involved, at least, initially. • Trees with existing declines may be that much more vulnerable to the effects of climate change.

A. Because most forest pests are sensitive to temperature, even modest warming could speed up their metabolism requiring more food, increasing mobility & distribution, increasing reproduction. B. Deer, invasive plants and earthworms cause damage to native flora, soil structure and nutrient cycling. Their effects by will be accelerated. C. Trees maladapted to their existing sites will become more and more drought stressed. Conversely, some species will benefit, by gaining abundance and/or distribution. Others may be unaffected.
