TUNDRA REGION WITH FFORDS, GLACIERS AND MOUNTAINS, KONGSFFORDEN, SPITSBERGEN |
Facts about the Tundra and what is the
Tundra?
Following the forest towards the north
of the planet, you will find stunned willows and birches. Further on, it is
replaced by conifer and the vast treeless plains where only low vegetation
survives. There are sedges, rushes, perennial herbs and dwarf woody plants,
bryophytes and lichens. This is the tundra.
The ground is permanently frozen. The
permafrost stops drainage of the soil and roots can't penetrate. It is frozen
in winter and thaws in summer with a waterlogged surface.
Sedges and rushes grow in boggy
areas. Dwarf willows and birches in well-drained areas. The mosses are
protected in the winter by a cover of snow from the icy condition.

Tundra Plants
For one or two months the sun raises
high enough to melt the snow in the summer. This is the time when nature comes
alive and the legendary summer carpet of flowers in the tundra comes alive. You
will find in abundance forget-me-nots, blue anemones, Canadian dogwood, lupins
and saxifrage. It also buzzes with life of insects breeding in pools of melting
snow. There are millions of mosquitoes, midges, flies, plant-sucking weevils,
mites, springtails, blowflies, dung beetles, spiders and caddisflies. The ponds
and marches are full of crustacceans, aquatic insects, fish and plants.
This offers a great feast and is an
invitation for birds to migrate to the tundra. They breed and rare their chicks
there. It is teeming with ducks, swans, geese, plovers, sandpipers, phalaropes
and other waders.
CARIBOU |
Tundra Animals
After they flew south the reindeer
and caribou herds moving into the tundra and have a feast on aromatic plants.
Their hooves are adapted, being broad, flat and cleft, to be sure-footed on the
snow and icy ground. The arctic wolves follow the reindeer and caribou herds.
Their smell is 100 times more sensitive than man.
The long-tailed skua favourite meal
is the lemmings. The period when the lemmings breeding plentiful; it also
encourage the skuas to breed successfully. The skuas breed on the tundra and
spend winters at sea.
ARCTIC WOLF |
When the Arctic Wolves trying to
attack the Ox calves; the herd of musk oxen stand tightly packed in a circle,
with a barricade of horns outwards toward the wolves.
The large herds of caribou crossing
the tundra feed on lichens which were uncovered by the melting snow. They head
towards the north in the summer to calve. Males and females have antlers.
The moose coming into the tundra
eating the aquatic vegetation. Usually a third of their calves are killed by
wolves and other predators.
Red throated divers raise their
chicks there, alongside other migrate bird. They also called loons.
It is amazing that the American
porcupine sits up on a tree. Its diet is roots, berries, flowers and seeds
which are plentiful in the summer.
In places where there are shrubs and
dwarf trees; the Lapland buntings raise its chicks there. In the winter they
join the snow buntings.
SNOWY OWL |
The snowy owl's favourite prey is the
lemmings which she catches at dawn and at dusk. The male is white all year

their hind legs, in their white coat. Maybe they get a better view.
Red foxes adapt to most environments
- such as the Arctic tundra.
