The forests of Canada are diverse, dynamic and are the basis of life in Canada and in some cases the world. They modify the climate, providing oxygen, shade and soil sytability. They are used by a large number of humans : individuals, Aboriginal groups, environmmental organizations, scientists, trappers, recreationalists, and the forest industry. Most native trees migrated here during the last 10,000-20,000 years since the melting of the Pleistocene ice sheets. Canadian f orests are divided into 15 terrestrial ecozones, which contain the 8 Forest Regions of Canada (). The Forest Regions are groupings of forest types who have similar site requirements such as soil and climate. Trees can also be described in terms of their hardiness zone. Hardiness is the ability of a tree to survive climatic stress in a given area and are based on climate. Forests are dynamic ecosystems - a complex, functional system of interacting and often independent biological, physical and chemical components. As such, they are subject to many forces seeking to change and modify it. In Canada, many of our forest types are driven by " disturbance agents " or factors which seek to change the forest on a temporary types through biological or non-biological events such as forest fires, windstorms or even insect infestations. These factors are also in many ways a measure of forest health. A healthy forest is one that maintains and sustains desirable ecosystem functions and processes. Indicators of healthy forests include ones related to biodiversity change, resilience, wildlife habitat, aesthetic appeal, and resource sustainability. Both natural and human influences can impact on forests in positive and negative ways. In fact, natural influences, such as fire, insects, and disease are essential for the regeneration and succession of most of our forests.
