Less than 200 mm
Characteristics
Arctic Cordillera Ecozone
It ranges from the northeastern
parts of Nunavut to the northern
- The
north of the Arctic
parts
of Quebec
Cordilleran is cold and dry
Throughout the year
- Where the ice caps are
located
Basically no growing
season in this ecozone
This ecozone consists
Of a range of mountains
- The south of this
ecozone is more fortunate
having a more humid
climate and cool summers
with long hours of sunlight
- Where the glaciers are
located
Overview of the Land
• Main landform is mountains
• Changes in elevation
• Approximately 75% of this ecozone is exposed bedrock
• The other 25% is glaciers and ice fields
➥This is the ultimate landscape for Nunatak
• Soil in this area is limited and is a type of soil known as cryosolic soils
➥ With these factors the land only supports herbaceous vegetation
Positive
• This ecozone has a protected park called “Quttinirpaaq National Park”
which includes 7 fjords, a variety of glaciers and the world’s largest lake
north of the Arctic Circle called “Lake Hazen”
• Contains unique icy scenery
Negative
Temperatures can reach as low as -40C and within a year there are 10 months
of inhospitable weather cold enough to keep water frozen. Therefore, with so
little frost-free days in this region, the area can only support herbaceous tundra
vegetation. People in this region have to hunt, fish and trap for survival leaving
them deprived of vitamins C and D and more that crops provide.
Human Activities
Only about a thousand people live in this 196,235 km2
(75,767 sq mi) island.

Interesting Points
Geographic Issue
» World’s tenth largest
island and Canada’s
third largest island
» Covers 2.5% of
Canada
» This ecozone is known
for its unique and
broad ice and
mountains however,
due to global warming
in the 20th century the
Ellesmere Ice shelf
reduced by 90% (this
covered the Northwest
coast of Ellesmere
Island)
Overall
-
Small area
Has a small population
Very Cold
Little plants and animal species
Not much resources
Untouched Land
