Sudden Oak Death is a potentially injurious pest in Canada. Oak and other related species are valuable hardwoods in the Deciduous Forest, Great Lakes-St. Lawrence and Acadian Forest Regions in Canada. Oak species are also valuable as shade trees in urban areas. Their wood is in much demand for furniture and flooring for both domestic and overseas markets.
Oaks also provide valuable habitat and food source for wildlife.
Rhododendrons and azaleas are popular ornamental plants in Canada. There is a significant movement of rhododendron stock from the United States into Canada. The recent discovery of Phytophthora sp. Huckleberry bushes, which occur throughout the pacific northwest, may bridge gaps between oak forests and could play an important role in spreading the pathogen. A Guide to Writing and Editing .
