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.
Obabika Old-Growth Forest
Obabika old-growth forest is an Eastern White Pine and Red Pine dominated old-growth forest at the north end of Obabika Lake, just west of the Temagami region of Ontario, Canada. At in size, is commonly considered to be the largest remaining white pine dominated old-growth forest in the world. It is also sometimes called Chee-Skon Lake old-growth forest, or Wakimika Triangle old-growth forest. This area was slated for logging in 1989 and was protected largely as a result of a blockade on Red Squirrel Road in which 344 protestors were arrested, including future Ontario premier Bob Rae. The oldest trees in the Obabika old-growth forest are confirmed to be at least 375 years old, but a diversity of age classes occur in this forest. Another important feature of the area is the spirit rock, a column of rock on the shore of Chee-Skon Lake that is of spiritual significance to the Teme-Augama Anishnabai people.
