I was the field auditor/evaluator in this 4-year long research study for PG&E and Phytosphere Research of Vacaville. The project was designed to compare two different methods of pruning trees below overhead electric lines. It was a very well-designed matched pair study that I was proud to participate in. We were able to provide some very good date to PG&E which I hope will be useful in reducing their line clearance costs, and eventually our electric bills.
