Wank (mountain) - Physical Characteristics

Physical Characteristics

The mountain's geology, which is dominated by calcareous rocks, is typical of the Bavarian Alps. Its climate is also typical of the region. Precipitation is high, ranging from about 1,300 millimetres (51 in) at valley level to 1,800 millimetres (71 in) at the summit. It peaks in the summer and is lowest in winter. Wank's mean annual air temperature ranges from 7 °C (45 °F) in the valley to 3 °C (37 °F) at the summit. The prevailing wind comes from a westerly direction but for about 30 to 40 days a year the mountain experiences a warm, dry föhn wind. A local wind system also operates in the area giving a daily uphill/downhill circulation. Inversion layers occur for about 30 days per year, predominately in the autumn and winter.

Wank was originally covered by a forest consisting of a mix of spruce, fir and beech trees. A process of man-made deforestation that began in the Roman period, when the trees were cut down and the mountain's slopes were grazed by horses, sheep, goats and cattle, resulted in much of the forest being destroyed by the 15th century. Forestry in the area was taken over by the Bavarian government in 1803 but the former forest cover did not regenerate due in part to the continued use of forest lands as pasture, storms and browsing by game animals. As a result, the current Wank forest is predominately spruce (about 75%) and pine (15%). Forestry programmes are currently underway to improve the arboreal diversity of the mountain.
