One reason for confusion about tree damage from construction involves the dormancy of trees during winter. Another factor is that trees may not show symptoms of damage until 24-months or longer after damage has occurred. For that reason, persons uneducated in arboriculture science may not correlate the actual cause and resultant effect.

Various organizations, such as the International Society of Arboriculture, the British Standards Institute and the National Arborist Association (about 2007 renamed the Tree Industry Association), have long recognized the importance of construction activities that impact tree health. The impacts are important because they can result in monetary losses due to tree damage and resultant remediation or replacement costs, as well as violation of government ordinances or community or subdivision restrictions.

As a result, protocols for tree management prior to, during and after construction activities are well established, tested and refined. These basic steps are involved:

* Review of the construction plans
* Development of the related tree inventory
* Application of standard construction tree management protocols
* Assessment of potential for expected tree damages
* Development of a tree protection plan (providing for pre-, concurrent, and post construction damage prevention and remediation steps)
* Development of a tree protection plan
* Development of a remediation plan
* Implementation of tree protection zones (TPZ)
* Assessment of construction tree damage, post-construction
* Implementation of the remediation plan
