The following is a press release from PG&E dated December 5. The initial import of the release is to notify and explain to residents of Round Mountain, Montgomery Creek, and Big Bend the reasons that helicopters would be flying low over their areas on Tuesday, December 7. The release gives details about the growing number of trees that have died as a result of the drought or are threatened by insects and disease as a result of weakened resistance. After the aerial check, foresters will follow up on foot to inspect trees. Then private landowners will be contacted. Dead or infected trees will need to be trimmed or removed.
Pacific Gas and Electric Company (PG&E) will be flying low by helicopter in Shasta County on Tuesday to check for drought-stricken trees near power lines. Flights will occur over Round Mountain, Montgomery Creek and Big Bend.
Residents are advised that the helicopter will fly low – about 200 to 300 feet – along distribution power lines.
PG&E is using a contract helicopter service to fly foresters to check for trees weakened by the drought. This patrol is in addition to the annual patrols PG&E does along power lines to identify trees and vegetation in need of pruning and removal. Weakened trees and branches can fall into power lines, leading to outages and even wild land fires.
The drought has weakened and killed many trees and left others susceptible to disease or insects. After the flights, foresters will hike to the trees in question for an up-close inspection to verify tree conditions. Once a forester confirms a tree needs to be removed, PG&E will work with the property owner to schedule a contractor to cut the tree.
Consecutive years of drought have taken a toll on trees and even some trees deemed healthy six months ago have since succumbed to the dry conditions. The U.S. Forest Service recently identified an exponentially growing rate of tree mortality in California. In 2014, 11 million dead trees were identified throughout the state. That number grew to 40 million in 2015 and 102 million in 2016.
While tree mortality is more serious in 10 counties in the southern and central Sierra Nevada Mountain region, the Forest Service also identified increasing mortality in the northern part of the state.
Weather permitting, all flights will occur between 8 a.m. and 4 p.m.B>>
