Residents in Eastern Shasta County may see some low flying helicopters this week. They’ll be flying at 2-to-300 feet along electrical distribution lines checking on drought-stricken trees for PG&E. Wednesday between 8AM and 4PM flights will take place near Round Mountain and Montgomery Creek. Several years of drought have made trees susceptible to bark beetles and other insects, and foresters will be riding in the copters to spot trees that are threatening power lines. Trees identified from the air will later be inspected on the ground, and then the landowners will be contacted to schedule tree work. The Forest Service says that in 2014 there were 11 Million dead trees in California. In 2015 the number grew to 40 Million and last year it was 102 Million. Investigators are still trying to determine if trees into power lines were to blame for the wine country fires. That’s already been identified as the cause of the Helena Fire in Trinity County.
