Overview

Urban Forestry's guidance for consulting arborists, tree care specialists and foresters on the content of an arborist report filed with a development application, a tree removal or injury application, or a ravine permit application. It covers contact information, location, species, size, nature of work, condition rating factors, the five by-law categories, the client's reason for removal, replacement planting and the arborist's recommendation, then tree retention and protection. Two worked example reports close it — a single removal, and a removal with three trees retained through a house addition.
