Pilot management programmes for Nature 2000 sites, “The Małopol-ska Vistula gap”, “The Vistula gap in Małopolska” and “The Zwolenka river valley”

With the financial support of the European Union, as part of the Twinning Project PHARE PL/IB/2001/EN/02 "Implementation of NATURA 2000 Network in Poland", management plans of selected sites within the NATURA 2000 network have been prepared. The project was carried out by IUCN with considerable support from the French Ministry of Ecology and Sustainable Development and the Polish Ministry of the Environment. Part of this project, apart from preparing plans of management of selected pilot areas within the NATURA 2000 network, was preparing methodological tools for area management. Among other things, programmes have been prepared for the management of two existing sites: a bird site “The Małopolska Vistula Gap” (PLB140006) and a habitat site “The Zwolenka River Valley” (PLH140006) as well as a planned habitat site “The Vistula Gap in Małopolska. The following strategic aims in protecting habitats and species have been formulated: 1. Sustaining natural processes that shape the Vistula Valley, maintaining suitable habitat conditions for ecosystems to function, especially maintaining and, if necessary, recreating appropriate water relations as well as maintaining the high quality and appropriate physico-chemical composition of local waters. 2. In forest ecosystems and plantings in the Vistula Valley the main strategic aim is sustaining or re-naturisation of ...

Water as the forest habitat quality differentiating factor within flooding areas of the NATURA 2000 system

Riverline woodland habitats are extremely valuable in terms of ecology, and many of them are included to the Natura 2000 network. Unfortunately, in recent decades water conditions on these areas have considerably changed, what is causing their degradation. For that reason, studies on differentiation of habitats determined by variable water conditions in flading areas have been curried out. The case study was Oława-Lipki flood polder, covered with forest. This article presents an analysis of water and habitat conditions executed in years 1997–2000. ...

Environmental aspects of water management at the detention reservoir as an example of designed Racibórz reservoir

Detention reservoirs are designed for rise interceptions of flow intensity exceeding the flow capacity of the discharge devices. With this follows gradual refill of the hemisphere reservoir, this results in a decrease of runoff size and a diminishing culmination. Detention reservoir designed in Raciborz will be located on the naturally valuable areas including grounds classified into Natura 2000 network and its influence will be seen at a flight of 230 km on the Odra River. The research analyzed the potential influence of the water management on the natural environment of the river valley. The flood heights are put together in the reservoir bowl. ...

Environmental impact assessments of recon-struction of the Chróścice dam for Natura 2000 the special protected area Grądy Odrzańskie

Hydrotechnical investments in Natura 2000 areas may characterized potentially significant conflict for natural environmental values. For limitation of negative effects of its implementation it must be execute natural inventory and va-lorisation and next evaluation of impact for natural environment. Basic principle is prevention and restrict to losses in natural environmental. Eherever losses are inevitable it should be indicated methods of natural compensation. Evaluation of condition of natural values in The Chróścice Dam areas not indicate on an occur-rence of significant limitation for reconstruction of dam. Most conflict building works will run between flood embankments. To restore habitats of species protected in Natura 2000 Special Protected Areas Grądy Odrzańskie metods of natural compensation were proposed. Natural compensation was agreed with build designers. On the basis of investigation made sugestion, that natural values of Odra Valley are protected in reconstruction of The Chróścice Dam.     ...

ALLIANCE IN THE AREA OF KALINA-LISINIEC SPECIALITY PROTECTED HABITATS IN THE MIECHOWSKA UPLAND

The Malopolska Upland, with its beneficial geo-morphological, soil and climatic conditions is a place where xerothermic plant communities are quite numerous. Natural hazards to which these communities are exposed cause that in a vast majority they have been covered by various forms of protection. Vascular flora of Inuletum ensifoliae alliance in the Kalina-Lisiniec Special Habitat Protection Area, which reveals a considerable biodiversity, unique character and occurrence of protected and endangered species, plays a crucial role in the natural environment of the Miechowska Upland. The habitat covered by Inuletum ensifoliae alliance are mainly sandy loams and silt deposits. These are usually moderately poor (mesotrophic) soils, in vast majority alkaline, dry or ranging from dry to alkaline. Habitat conditions are characterized by a full or moderate insolation. ...

AN ASSESSMENT OF THE HYDROGEOLOGIC CONDITIONS AND IDENTIFICATION OF ECONOMIC THREATS TO THE PRIMULA FARINOSA POSITION IN SĄDECKI 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. ...
