Background: Austrian scientists are waging a campaign against avalanches, which bury many people each year and bring chaos to communications in the Alpine Provinces.
On the Patscharkofel Mountain, near Innsbruck, a "climate house" is being built. In it, the scientists will be able to reproduce a wide range of mountain weather conditions, and to study their effect on mountains trees and shrubs. They aim to find out how trees and shrubs can be made to grow in the rigorous climate of high altitudes, where they could be used to prevent masses of snow from crashing down into the valleys.
Thee has been a sharp increase in the frequency of avalanches in the past ten years. The gradual recession of trees from the higher altitudes is believed to be responsible. Out of 2,000 incidents in inhabited areas of the Tyrol between 1951 and 1954, two thirds occurred in areas where there used to be forest.
In the "climate hose" - climbed to be unique and due to go into operation this spring - it will be possible to creates big variations in temperature, wind-speed, light and humidity. Instead of waiting years to observes the growth of trees planted experimentally high up on the mountains slopes, scientists will be able to obtain results in a few months. They will also be able to study the effects of abnormally cold spells which can kill a forest after years of normal growth.
