With this conference, the ISA Ontario Education Committee aims to explore the inner workings of trees and the impact they have on the world around them. By dissecting the internal operations of a tree, we can begin to understand their connection to each other and the impact they have on society. Trees provide benefits far beyond providing oxygen and carbon sequestering, so it is important for arborists to understand how trees work and why they do what they do. This eagerly anticipated 2019 event will see us return to Caesars Windsor Hotel and Casino. This venue offers a luxurious setting with exciting entertainment opportunities. There are a variety of amenities to be enjoyed. The City of Windsor has a full arboricultural history and the proud International Gateway between Canada and the United States.
