Urban Tree Threat Response Guide for Insect, Disease and Environmental Threats to Urban Trees in Arizona and New Mexico
The Guide provides detailed information about 24 insects and diseases that weaken or kill urban trees. Some of these are currently present in Arizona and/or New Mexico. Others could make their way here in coming years. Five environmental/cultural factors that affect urban tree health are also addressed. The 50-page Guide can be viewed on screen or downloaded. The format enables it to be shown as a computer-projected presentation.
