COUNTRYAAH, Liechtenstein, despite its small size, can be divided
into three topographically different areas: the Rhine canal,
which is located at about 450 m above sea level. the castle
Vaduz and the mountains, which with the summit Grauspitze
reach 2 599 m above sea level. The Rhine sink is
tectonically landscaped but affected by glacial and fluvial
erosion and accumulation. Bergen, which belongs to Rätikon,
is the boundary zone between the Western Alpine Hell School
and the Eastern Alpine. Flysch, ie degradation products from
the alpine fold, cover large parts of the mountain areas.
The climate is similar to that of the Austrian and Swiss
Alps (see Austria: Climate) and varies with altitude above
sea level. The rainfall normally amounts to between 1,050
and 1,200 mm per year, but can rise to 1,800 mm in the
mountainous regions. Summers are hot with temperatures of up
to 28 °C; in winters the temperature can drop to –15 °C.
About 25% of Liechtenstein is wooded. The forests are
largely planted and poor on other plants and animals. Above
the forests and vineyards, however, there are alpine meadows
with richer fauna and flora.
Just over 40% of the country's area is protected by
nature, an internationally high figure. By far the largest
area is dedicated to the protection of mountain fauna.
