Erfassung und Bewertung der Landschaftszerschneidung im Landkreis Wernigerode / Harz

Abstract

In this article first computer processed results on landscape dissection of the district Wernigerode (SaxonyAnhalt) were presented. The term "landscape dissection" is based on landscape-ecological model approaches. The concept distinguishs between causes of dissection (technogenous linestructures, material- or energystreams) and effects of dissection concerning animal movements. The statewide applicable methods for analysing and evaluating the dissection of landscape were shortly explained. The results content data of potential dissection elements (footpathes, roads, railways, power lines), of dissection effects (barrier-, disturbance- and collision effect), of the largest undissected areas and their value as resting places for species sensitive to disturbance and parameter of dissection per area.
