Société internationale d’arboriculture - Québec inc.

The Société internationale d'arboriculture Québec inc, commonly known as SIAQ, is a group of professionals dedicated to the maintenance and preservation of trees. Our mission is to encourage a greater appreciation of trees, promote research, technology and the professional practice of arboriculture. The SIAQ is a non-profit organization founded in 1977. It is a local chapter of the International Society of Arboriculture, an international organization present in more than 60 countries. Our objectives are to promote and improve the practice of arboriculture through training and information. The general public can therefore find a wealth of information in our pages, more specifically under the heading "Arboriculture". We wish to promote professional arboriculture by making the general public aware of the importance of hiring a professional for tree care. Arboriculture professionals who are members of SIAQ have access to many resources to help them in their practice.
