Trees in their natural enviorment have evolved to develop a high degree of resistance to threats from insects and diseases. Conversely, urban trees face increased challenges due to their harsh growing conditions, leaving their resistance compromised and more vulnerable to attack.
It is vital that potential problems are identified and strategies created to protect trees in the urban and suburban landscape, as scale insects, ambrosia beetles, foliage diseases, trunk borers, decay organisms, and other pests and diseases are attracted to weakened trees.
