2.a.8 Svydovets (Ukraine)<br />

Abiotic conditions<br />

Being a part of the CBR, this cluster is located on the slopes of the Svydovets Ridge and<br />

on its offshoots at 350-1.883 m and it belongs to the Svydovets-Chornohirskyi Physical-<br />

Geographic district of the Polonynsko-Chornohirskyi Region of the Eastern Carpathian<br />

Subprovince.<br />

The flysch formations with dominating clay and aleurite are present in the geologic<br />

structure of the cluster, and sandstones with admixtures of limestone occur here.<br />

The western part of Svidovets is characterized by the Middle-Mountain landscapes<br />

complicated by erosion-denudation activity of streams. Besides, the fragments of the High-<br />

Mountain Meadow denudation leveled surface are characteristic features of the Svidovets<br />

summits; they are mainly flat saddles and gently sloping foothills, and they are complicated<br />

by the signs of an ancient icing with typical glacial forms (karrens and trough valleys).<br />

The climatic conditions here vary from moderate-warm to cold. Annual precipitation is<br />

750–1.500 mm.<br />

The cluster covers the drainage area of the rivers Chorna (Black) Tysa and Kisva (right<br />

tributary of the Tysa River). A dense network of streams curves this area.<br />

Acid (dystrophic) brown soils totally dominate in the topsoil of the cluster, and only<br />

small patches on rocks are covered with primitive and initial soils. The characteristic features<br />

of soils here are the high pH level (ca. 4.0), a powerful profile of 80-100 cm; rich content of<br />

rough humus (10-12% in upper horizons and 1-2% in transition and bottom horizons), and a<br />

low content of amphoteric bases (degree of saturation less than 30%). Brown soils on<br />

limestone rocks have a two-member grid (double structure). The upper part corresponds to<br />

acid (dystrophic) brown soil, and the bottom one to eutrophic saturated with calcium brown<br />

soils with neutral reaction. Soils are very stony, mostly middle-loamy with good penetration<br />

of water and air into them.<br />

Biota (vegetation and flora)<br />

The total area of the cluster “Svydovets” is 8.670 ha: core zone is 1.525 ha and buffer<br />

zone is 1.145 ha, and here is the richest flora within the Ukrainian Carpathians. Beside the<br />

forest vegetation belt, the High-Mountain belt (mainly subalpine and partly alpine) occur<br />

within the Svidovets site.<br />

Soil-climatic conditions are optimal for beech, therefore its communities here are of a<br />

climax character, and they are mainly Fagetum rubosum hirtae, Fagetum asperulosum,<br />
