Location
• The Hudson plains stretch from
Manitoba to Quebec along the southern
eastern edge of Hudson Bay.
Quebec
Climate
• Canada contains a quarter of the world's wetlands,
and the Hudson Plains ecozone's poor drainage has
resulted in the largest continuous wetlands in the
world.
• Hudson's Bay moderates the temperature in
summer, but the ice that covers it in winter prevents
most of this; average summer temperatures are 11˚C,
but in winter the average temperature is -18˚C.
• Precipitation ranges from 400mm in the northwest to
800mm in the southeast.
• It has short cool summers and severely cold winters.

Geology and Geography
• The terrain here is flat, and the poor
drainage encourages the creation of
wetlands and bogs. Palaeozoic and
Proterozoic sedimentary bedrock slopes
gradually towards Hudson Bay.
Vegetation
• Vegetation here follows two basic patterns. The first ranges from
north to south; in the north, the terrain is treeless tundra, but in
the more southern taiga trees appear, getting thicker as you
move south.
• The second pattern follows altitude. The drainage here is poor,
so the trees are only found at the drier higher altitudes, while the
lower altitudes lack trees.
• Some characteristic tree species are black spruce, white spruce,
and tamarack.
• Other plants include eriacaceous shrubs, cotton grass,
sphagnum moss, northern Labrador tea, and Lapland rosebay.

Animals
• The assortment of animals is highest in
summer, when migrating birds appear in huge
numbers to breed.
• The region is more famous for its biting insect
population, which takes advantage of the poor
drainage to breed in huge numbers.
• A single hectare is estimated to be able to
produce ten million black flies, and other biting
insects.

Soils
• The mineral soils that cover much of the area are
finely-textured silt and clay deposited by both marine
and glacial processes. Outcrops of the underlying
sandstone and shale are rare.
• Since glaciation, the flat terrain, impervious soil and
poor drainage have promoted the development of
wetlands throughout the plains. Web-like or polygon
patterns in organic soils are typical of northern
wetlands.
• In this soil there is very little moisture and minerals
because of the poor drainage. There is no topsoil so it
is not very good for agriculture and definitely not
loam.
• The map above is a map of soils for different
regions. If you look closely the Hudson Plains
is mainly covered by the light blue and brown.
That means it is made up of Brunisoic, and
Cryscilic.
Humans
• A lack of timber and minerals means
that tourism and other activities
basically explain why there is only 10
000 people who live here make their
living.

Hudson Plains Slope and the Hillshade
Basically both maps are showing you the elevation of the
land, like how high or low it is. By analyzing each map I
picked up that just like it is known for it has a rather flat
terrain.
Here is a quick recording of
the Hudson Plains Region
QuickTime™ and a

Hudson Plains Arc Scene
In the previous slide I showed you a quick view of
the Hudson plains region. While travelling through
you could see that it is a rather bump terrain.
Although this is not entirely true, the Hudson plains
is knows for its flat terrain. It is a pretty dry region
also so not very good for agriculture.
