Arborist Reports

Browning Arborist Consulting offers arborist reports. Arborist reports are required by most cities in the lower mainland of British Columbia, in order to get a tree removal permit.

 

The city requires that an ISA Certified Arborist and ISA Certified Tree Risk Assessor (TRAQ) conduct a tree risk assessment on the tree or trees in question.

 

In order for there to be any consideration of risk there must be something of high value in the target zone. Such as human traffic, cars parking spot or a building. If the tree has nothing in the target zone, for example a tree in the middle of the field, there is no risk.

 

The arborist needs to conduct the assessment and come back with some evidence that the tree is unhealthy and possesses a risk of failure whether that is a part failure or whole tree failure.

 

If the tree is healthy , even if it has a target rich target zone, it won't be considered a risk and will not be recommend to be removed.

 

Every situation is different, even if you are not looking to remove your tree or trees, having an Arborist conduct a tree risk assessment with a recommendation at the end of the report is a great way of knowing the current condition of the trees on your property.

 

This will give you a plan on how to look after your tree(s) moving forward and it normally gives you information about your tree you didn't know. Early intervention on some trees can be paramount in preventing a large part failure which could be the beginning of the end for the tree. 

 

Most cities in the lower mainland require an arborist report in order to approve a removal permit on a protected tree. A protected tree can be any tree that is considered oversized (20-30cm DBH depending on the city), a tree that is a replacement tree that was required to be planted by the city or a tree of a specific species, such as a Garry Oak in the city of Surrey.

​

Regardless of whether it is a standard level 2 tree risk assessment, a level 1 tree assessment on numerous trees or a level 3 assessment, a more in depth assessment, such as an increment bore, aerial assessment or a root excavation with an air spade. We have all your tree risk assessment needs covered.
