AN ASSESSMENT OF THE HYDROGEOLOGIC CONDITIONS AND IDENTIFICATION OF ECONOMIC THREATS TO THE PRIMULA FARINOSA POSITION IN SÄ„DECKI BESKID

Primula farinosa position is the only area in Poland where this plant occurs native. This area has status of Nature 2000. The work contains chosen physical properties of soil in the area of Primula appearing, and also at surrounding area. On this base possibilities, conditions and a scope of performing engineering works and works associated with acquiring wood in the precinct were determined for the station. Presence of clayey soils was identified, with pour ability of the filtration (from 2.95 ÷ 5.60 m•per twenty-four hours). Soil inside the station is marked by a quite large content of organic parts (to c 30%). Outside the station contents of organic parts isn't large (to c 10%). To preserve stability of the hydrological conditions of the station it is crucial to remain the continuity of soil cover layer at this area and at area situated above. Therefore in this area a prudent forest management is proposed, skidding of wood using additional resources minimizing damages of the soil cover layer, reclamation of tracks after skidding of wood, discontinuing engineering work associated with excavations, and proper surface draining of already existing roads. ...
