Forests of Canada
Named forests are found within eight distinct regions. These forests may also be part of ecosystems, a number of which extend south into the United States. 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. This system extends south into the United States.
Geography of Ontario
Köppen climate classification Dfa is represented in the southwestern tip of Ontario including the city of Windsor. Dfb climate classification is present in London and the southern/western section of the Golden Horseshoe region including Hamilton, Niagara, Oakville and the city of Toronto, have a moderate humid continental climate, similar to the lower Great Lakes portion of the Midwestern United States. The region has warm, humid summers and cold, usually moist winters. Extreme heat and cold usually occur for short periods. It is considered a temperate climate when compared with the remainder of continental Canada. In the fall and winter, temperatures are moderated by the delayed cooling of the Great Lakes; this effect is reversed in spring and summer when afternoon warming is tempered. The lakes' moderating effects allow for a longer growing season than areas at similar latitudes in the continent's interior; some areas exceed 200 frost-free days and have an annual mean temperature of 10 °C (50 °F). Both spring and fall generally consist of mild days and cool nights but are prone to drastic temperature changes over a short timespan. Annual precipitation ranges from 75 to 110 cm (30–43 in) and is well distributed throughout the year with a usual summer peak. Upland areas in this region have cooler conditions, generally more precipitation (especially snowfall), putting them into the Dfb climate scheme. Most of this region lies in the lee of the Great Lakes, making for abundant snow in some areas (London, Goderich for example) over 2 m (80"), while some other areas are not in the direct snowbelt and receive closer to an average of 1 m (40") of snow per year.
