Central Canadian Shield forests
This ecoregion consists of rolling hills, lakes, bogs and rocky outcrops covering a large curved swathe on the Canadian Shield from eastern Manitoba and Northern Ontario running southeastwards through Thunder Bay District to the north shore of Lake Superior and then northeastwards into western Quebec. The area has a cool climate with summer temperatures averaging around 13°C dropping to a very cold -17°C in winter, with the hills around Lac Seul in northwestern Ontario being warmer and wetter than most of the area. Average rainfall in the eastern side of the ecoregion is 550mm per year, rising to 750mm in the centre (near Lake Nipigon for example), up to 900mm in the west. Specific areas include Lake Nipigon and Big Trout Lake (Ontario). These forest contrast with more severe boreal forest ecoregions such as the Eastern Canadian Shield taiga to the north, which covers most of Northern Quebec and Labrador.
List of trees of Canada
This list compiles many of the common large shrubs and trees found in Canada. 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).
