The dynamics of the timberline ecotone on the asymmetric ridge of the Babia Góra Massif, Western Carpathians

Abstract

Timberline ecotone (TE) generally developed because the temperatures in the environment were too low. There are other overlapping biotic and abiotic factors which affect the TE. The main aim of this work was to determinehow the asymmetry of Babia Góra’s ridge influences the location and characteristics of the timberline ecotone nowadays, and how the ridge influenced the timberline ecotone in the mid-20th century. The asymmetryof environmental conditions means the timberline has formed in two extreme environments: on the sunny and gentle southern slope (40% of the timberline length) and on the cold, humid, steep northern slope (another40% of the timberline length). The southern slope of the ridge shows a progressive timberline length of 86%. In turn, 81% of the timberline on the northern slope is in a stable ecotone.
