Arborist Report

Arborist reports give detailed information regarding the overall health and condition of a tree, documents any defects or concerns such as disease or structural damage, and offers recommendations for each tree in question. We provide timely arborist reports to ensure your job is completed to your specifications and meets City requirements.

 

Tree Risk Assessment

A tree assessment is a process of evaluating the health, structure, and safety of trees. It can involve a detailed inspection of the tree’s leaves, branches, trunk, roots, and surrounding environment to determine its current condition and potential risks. These are often referred to as Hazard Tree Assessments or Danger Tree Assessments.

 

How to Recognize Tree Risk? Consider these questions when assessing a tree:

 

  • Are there large dead branches?

  • Are there detached, hanging branches?

  • Have any branches fallen from the tree?

  • Is there loose bark on the trunk?

  • Are there cracks or splits in the trunk or where branches are attached?

  • Has the trunk developed unusually?

  • Are there cavities or rotten wood along the trunk or in major branches?

  • Are mushrooms present at the base of or under the tree?

  • Has the area recently been altered by construction, changes in soil level, or installations of lawns or pavement?

  • Has the tree been topped or heavily pruned?

 

Evaluating the seriousness of these defects is best done by a certified arborist. Regular tree care performed by an ISA Certified Arborist will provide an opportunity to identify trees that have defects and unacceptable risk levels. Once the risk is identified, steps may be taken to reduce the likelihood of an incident or damage.

 

Performing an Aerial Inspection

An aerial tree inspection is a process of examining the condition and health of a tree’s canopy from an aerial perspective. This type of inspection involves a climber who is also a Certified Arborist and navigates throughout the crown of the tree to look for signs of damage, decay, or disease that may affect its stability and health. The aerial inspection is commonly used by arborists, forestry professionals, and property managers to assess the safety and maintenance needs of trees in urban and rural areas.

 

Tree Inventory and Management

Tree inventories are intended to provide the basic information on the plant population of a property in order to make informed management decisions. Our Certified Arborists provide tree inventory’s including tree ID, DBH & Height measurements, defects (if any), recommended management including hazard mitigation, pruning and pruning cycles. If you are considering having a tree inventory conducted on your property, one of the most important steps is to determine what information will be collected for each tree or for the site. Take the stress out of managing your trees. Contact Strathcona Tree Care to discover how we can help. Want to know your trees? The world of tree ID is huge and if we don’t already know it we will find it.

 

Arborist Monitoring

Some municipalities require that an ISA Certified Arborist needs to be on site monitoring construction activities near a critical root zone or tree protection barrier in order for the project to be approved. This is to make sure that the critical root zone of the tree(s) be protected as required by the city bylaw. The ISA Certified Arborist will monitor and document the works being carried out and provide a report including photos and what impact there was if any. The goal is to minimize any unnecessary damage to the protected tree root system during construction activities.

Frequently Asked Questions

What is Critical Root Zone Protection / Tree Protection Zone?

Each tree has a critical root zone (CRZ) that varies by species and site conditions. Critical Root Zone = Tree DBH in cm x 12.

In general tree protection zones are six to eight times the diameter at breast height and used to determine the optimal root protection zone (RPZ) setbacks are adjusted to suit the specific needs of the tree and site conditions. The optimal root protection zone is to be measured in the field from the outer edge of the stem of the tree. The RPZ is the area around the tree in which no grading or construction activity may occur without project arborist approval and is required for the tree to retain good health and vigor.

 

What does DBH stand for?

Diameter at breast height is the standard for measuring trees. DBH refers to the tree diameter measured at 1.4m above the ground.
