Destruction processes in the alpine zones

What is it about?

Research of destruction processes shows how sensitive are the alpine and subalpine zones to geomorphic phenomena. Even subtle damage of turf or forest can trigger a series of processes that can result into a degradation of the original ecosystem and create a new one at the same time. This paper focuses on 1. observation of destructed surfaces at horizontal and vertical level 2. variability of destructed/degraded surfaces (Does the avalanche chutes expand? Are we witnesses of spontaneous re-forestation at former turf areas? ...) We have used the aerial photographs as well as the field research to confirm slow gradual expansion of all destructive morphogenetic forms.Among the signs of the intensity of surface degradation are the erosive-avalanche chutes the most significant. Extension of five chutes was recorded during the period 1961-2012. The average intensity of the chute′s vertical erosion is 20-24 mm/year.

Why is it important?

Paper brings about findings on effect of avalanche controls and climate factors on development of soil and vegetation destruction. Variability of destructed surfaces hints increase/decrease of geomorphological processes and their linkage to geoecological factors.
