Talbot Mackenzie & Associates Arborist Statement - March 9, 2015

Re: 17a Jedburgh Road

At your request we visited the above mentioned site in order to further comment on the existing trees on the property as they relate to any proposed development on the property. We initially commented on the trees in our report regarding the address dated December 11, 2014.

The existing trees on the site are a mixture of: Douglas fir, Grand fir, Garry oak, Arbutus, and Native willow with the predominant species being Douglas fir. The majority of the trees grow in a grove that extends along the back of the property where it meets the E&N railway property. Trees that develop in this type of surrounding tend to develop low live crown ratios with the majority of the foliage concentrated in the upper portion of the canopy and will often develop asymmetric forms at the edges of the grove. As a stand they become accustomed to relying on each other to buffer against high winds and will develop limited rooting systems. When a portion of the stand is removed, it will often leave the remaining trees unsuitable to retain, particularly when new targets such as houses are introduced. In general, Douglas fir trees have a poor tolerance to construction impacts and changes in their drainage patterns as well as being prone to limb failure in high wind or heavy snow load conditions. For these reasons we generally do not recommend retaining mature Douglas fir trees that have developed in a grove in residential areas unless they can be retained as an intact grove in a low target area and isolated from any construction activities.

In our opinion the trees that offer the best opportunity for retention, should the property be developed, would be Garry oak trees that are known to have a good tolerance to construction impacts and any young trees that can be successfully isolated from construction activities and can better adapt to the new growing conditions that are going to be introduced.

Please do not hesitate to call us at 250-479-8733 should you have any further questions.

Thank You.

Yours truly, Talbot Mackenzie & Associates

Disclosure Statement

Arborists are professionals who examine trees and use their training, knowledge and experience to recommend techniques and procedures that will improve their health and structure or to mitigate associated risks.

Trees are living organisms, whose health and structure change, and are influenced by age, continued growth, climate, weather conditions, and insect and disease pathogens. Indicators of structural weakness and disease are often hidden within the tree structure or beneath the ground. It is not possible for an Arborist to identify every flaw or condition that could result in failure or can he/she guarantee that the tree will remain healthy and free of risk.

Remedial care and mitigation measures recommended are based on the visible and detectable indicators present at the time of the examination and cannot be guaranteed to alleviate all symptoms or to mitigate all risk posed.
