The Société internationale d'arboriculture Québec inc, commonly known as SIAQ, is a group of professionals dedicated to the care 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 active in more than 60 countries. Our objectives are to promote and improve the practice of arboriculture through training and information.
