The possibilities of wetland preservation within the depression cones of limestone and marl mines at Leśnica-Małogoszcz and Bukowa in the circumstances of deepening the level of exploitation
Journal Title: Annals of Warsaw University of Life Sciences – SGGW. Land Reclamation - Year 2014, Vol 46, Issue 4
Abstract
As a result of enlarging the depth of exploitation of raw rock material deposits of marl and limestone at Leśnica-Małogoszcz (Przedborsko- Małogoskie Range – Świętokrzyskie Voivodeship), initially to the level of +215 m a.s.l. and then +200 m a.s.l., a mine depression cone will develop, which may threaten the existence of wetlands included in the Natura 2000 network. The wetlands are present in the pre-gorge section of Łososina river flowing through Grząby Bolmińskie and Gnieździskie Hills, at the mouth section of its hydrometrically ungauged tributary – the Wrzosówka river. In the study there has been demonstrated the possibility of preserving the current state of moisture content of the habitats which exist here, taking into account the quantitative characteristics of the components of water cycle and morphological conditions. The analysis of water resources has shown that under the conditions of a functioning mine depression cone, they will be sufficient to supply endangered wetlands and enable their irrigation. The solutions of an ecohydrological character have also been put forward which would compensate the loss of water in the area within the open-pit mine depression cone. This would require the construction of dams (e.g. artificial rapids) in the Wrzosówka river bed and a system of ditches at the bottom of its valley.
