Utah Forest Insect and Disease Conditions Report 2012 (PDF | 2.2 MB) (Dec 2013)

This report focuses only on the impacts of insects, diseases, and other disturbances on the various tree species of the state. In 2012, insect and disease-caused tree mortality generally decreased from 2011. Decrease in insect mortality may be attributed to the depletion of suitable host type. General weather conditions have not been conducive to insect brood establishment, development, and survival. However, forest health conditions are still poor, and conducive to insect and disease activity. Adequate precipitation is necessary to maintain tree vigor, thereby resistance to insects and diseases. Drought conditions throughout the state continue to place more stress on forests that are already in poor health.
