The Canadian flora is depauperate because of the near total glaciation event in the Pleistocene. Due to the vast area of Canada, a tree that is common in one area may be completely absent in another. In particular, many warm-temperate trees can only be grown on the mild Pacific coast (where gardens may contain additional species not listed here).
For example, the Northern hardwood forest is an ecosystem located in large areas of southeastern and south central Canada as well as in Ontario and Quebec. The Great Lakes region includes white pine, hemlock and red maples, yellow birch, and beech trees.

Today, less than 1% of Canada's forests are affected by logging each year. [2] Canada is the 2nd largest exporter of wood products, and produces 12.3% of the global market share. [6] Economic concerns related to forestry include greenhouse gas emissions, biotechnology, biological diversity, and infestation by pests such as the mountain pine beetle.
A mature tree. Populus deltoides is a large tree growing to 20–30 m (65–100 ft) tall and with a trunk up to 2.8 m (9 ft 2 in) diameter, one of the largest North American hardwood trees.
