ABOUT US

Gabriel Deshaies-Daigneault, a forest engineer specializing in urban forestry for almost 15 years, is the founder and president of Xylème Inc. He has extensive experience in assessing urban trees, having inspected and analysed tens of thousands of trees to date and written as many reports with a professional signature (inspections, tree-cutting permits, preservation recommendations, tree appraisal, impact studies, etc.). Gabriel Deshaies-Daigneault has very good knowledge of the municipal environment through working as a consultant in urban forestry and arboriculture in many cities and municipalities, ever since the beginning of his career. In addition, he has been involved in the inventory and characterization of the tree heritage of many owners of large-scale tree populations.

Since 2015, Gabriel Deshaies-Daigneault has been certified by the ISA (International Society of Arboriculture) as a Certified Arborist. He has participated in numerous workshops and conferences related to arboriculture and urban forestry in order to maintain the highest standards of technical knowledge. He holds the vast majority of professional certifications available in Quebec, particularly in the area of risk management related to urban trees.

Did you know that….

  • The root area of a tree far exceeds the length of the longest branches. The roots can extend over a distance equivalent to more than twice the height of the tree!

  • Winter is the best time to inspect your tree's overall architecture. Think about it!

  • There are many myths about the relation between tree roots and foundation problems. Did you know that it is extremely rare for tree roots to cause direct and proven damage to the foundations of a building? There are no "jackhammer" roots, no matter what the species.

  • Just like in humans, stress is a predisposing factor for tree pests. For example, a tree stressed by a lack of water may be more vulnerable to insect attacks. Xylème can offer you advice to correct some of the stresses that are harmful to the health of your trees!

  • Trees are beneficial to the environment, not only because they improve air quality, but also because they capture atmospheric dust, reduce noise as well as cut heating and cooling costs.

  • The emerald ash borer (Agrilus planipennis) is a terrible enemy. Without preventive treatment, all attacked ash trees decline and die within just a few years' time. Control of this insect is essentially limited to detection, injection of conservable trees and progressive replacement of trees that have been cut down. Have you developed your strategy with a professional?

  • A tree whose roots have been disturbed by construction may appear normal for several years and may show only very few warning signs before breaking. A forest engineer specializing in arboriculture can help you recognize these signs before breakage occurs!

  • L’étendue racinaire d’un arbre dépasse largement la longueur des plus longues branches. Les racines peuvent s’étendre sur une distance équivalent à plus de deux fois la hauteur de l’arbre!

  • Trees can contribute up to 15% of the market value of a property, or the equivalent of about $45,000 for a property worth $300,000.

  • Pollarding consists of drastically reducing the height of the trees in an effort to limit the risk of breakage and increase the owner's sense of security. In actual fact, this practice is far from professional, as it causes tremendous damage to trees and increases the risk of breakage in the medium and long term. Moreover, this practice is prohibited in a number of municipalities.

  • Have your trees been inspected in the past 5, 10 or even 20 years? It may be wise and responsible to seek the advice of a forest engineer specializing in urban trees.

  • A forest engineer specializing in arboriculture can give you an independent, objective opinion on the work to be undertaken and advise you on the essential questions to ask potential contractors.

  • Planting a tree requires careful consideration of the desired species and planting site.      Although there are many varieties and cultivars available in stores, few species are truly well adapted to urban conditions. Xylème can inform you about the best tree species for your own situation and the functions you want the tree(s) to serve (for example, to provide shade, to act as a visual screen, to attract birds, etc.).
