The landscape of the Weidmoos was
formed by Ice Age glaciers. When the tongues of the
Salzach Glacier receded at the end of the last Ice Age,
about 17,000 years ago, they left behind an extensive
area of lakes in the Alpine foothills.
Such a lake was created in the area
of the present Weidmoos, and substantial deposits of
lake clay accumulated on its floor. Even today this
clay still prevents rainwater in the subsoil draining
away. In the course of time the lake silted up. Peat
mosses became established and over the millennia they
formed a layer of peat up to six metres deep. A bog
had been formed.
The bogs of Ibmer Moor, Weidmoos
and Bürmooser Moor extend over some 2,000 hectares,
making this the largest connected bog complex in Austria.
These large bogs used to be the home of a range of birds
which have now vanished entirely from the area, including
cranes and black grouse. Human activity - the cultivation
of the bogs which began in the 18th century and the
peat cutting which followed – has completely transformed
the landscape of the Weidmoos.
