Workshop 1: Insects & Diseases of Native Trees & Shrubs
The rapid spread of the Pinyon Needle Scale in the pinyon-juniper woodland in several areas of the state, was the biggeest forest health concern noted in 2013 on state and private lands. It was also detected heavily infesting transplanted pinyons in the Village of Oak Creek. This and other insects and diseases are the focus of this presentation.
