Corine Land Cover 2000 - Broad-leaved and Mixed Forests
Broad-leaved and mixed forests cover an area of approx. 8% in Tyrol. On the map the almost broad-leaved forest free areas of the Central Alps are clearly visible. Broad-leaved and mixed forests are found more in the alpine fringes up to an altitude of about 1500 m. Generally speaking, broad-leaved trees require a milder climate than coniferous forests (exception: green alders that often occur at the tree line).
The most common tree types in the mountain mixed forest are copper beeches, silver fir and in the higher regions an increasing number of spruces. In the south alpine regions at the Colline level (under 500 m), sub-Mediterranean varieties such as hop hornbeams; down oaks and common oaks are indigenous. Along the rivers and in the wetlands mainly broad-leaved trees (alder) are found.
The expanse of the broad-leaved and mixed forests today is, however, generally much less than its natural distribution area. On the one hand, reforestation measures mostly resorted to fast-growing spruces and, on the other hand, the lower, more climate favourable valley locations, were frequently used for arable land use. The mead forests, made up of broad-leaved trees, have mostly fallen victim to river regulations and other uses.
Because of their varied flora and fauna, broad-leaved and mixed forests are valued recreation areas. They are mostly completely or partly conservation areas. In the meantime measures are being taken to increase tree varieties and therefore also the proportion of broad-leaved trees in Tyrolean forests.
