What
is an Ecozone?
An
ecozone is a region based on it's ecological characteristics. It
is literally a "file folder" of information about that specific
area. These "file folder" contains information such as area,
landforms, climate, vegetation, soils, human activities and major
cities.
Which

There
are many different ecozones located in northern Canada. These
include the Arctic Cordillera, the Northern Arctic, the Southern
Arctic, the Taiga Plains, the Taiga Shield, the Taiga Cordillera, the
Boreal Cordillera, and a tiny bit of the Boreal Plains.
Southern Arctic
The Southern Arctic is 776 000 km2.
It experiences long winters of around -25˚C and short summers of up to
10˚C. There is a short growing season of around 80 days and there
is around 200 to 300mm of precipitation. There are some shrubs
but that is about all of the vegetation that you will find. The
landforms in this region consist of plains and hills of the Canadian
