Working in Trees is a field-oriented proven educational resource for entry level tree trimmers or climbers with little formal arboricultural training. It was originally developed for use as the textbook in the US Forest Service's Job Corps urban forestry training program. Working in Trees is a 525-page manual with all the subject material you need, arranged in a progressive, easily taught and understood sequence. Use it as a preliminary text, as a supplement to current instructional material, or supply it to your workers or students for self study.
