Protection and restoration of soil quality is an important task and should be a goal for arborists, tree owners, and managers. These Best Management Practices are the recommended practices for assessing, modifying, and conserving soils that support trees and shrubs in the urban environment. Because trees are unique living organisms, not all practices can be applied to all trees. A qualified arborist should write or review contracts and specification using national standards and this BMP. Departures from the standards should be made with careful consideration of the objective and with supporting rationale.
