    History, origins and importance of temporary ponds

    In Europe, temporary ponds are a naturally common and widespread habitat occurring, often in abundance, in all biogeographical regions from the boreal snow-melt pools of northern Scandinavia to the seasonally inundated coastal dune pools of southern Spain. Ecological studies in Europe and elsewhere also emphasise that temporary ponds are a biologically important habitat type, renowned both for their specialised assemblages and the considerable numbers of rare and endemic species they support. They are, however, a habitat currently under considerable threat. Most temporary ponds are inherently shallow and the majority are destroyed even by limited soil drainage for agriculture or urban development. The paper gives an overview of definitions of temporary ponds and examines their formation and abundance. The authors also summarise a visit to the Bialowieza Forest in Poland to investigate the occurrence of temporary ponds

    This describes two projects accomplished in 2010 by the Three Ponds Protective Association (TPPA) and several partners to identify and reduce soil erosion due to storm water runoff into the Milton Three Pond

    USING PLANTS FOR GREENING OF TAILING PONDS OF IRON ORE COMBINES OF KRYVYI RIH AREA

    The tailing ponds of the iron ore-dressing combines occupy thousands of hectares in Kryvyi Rih area and create a serious ecologic problem in this region. If the surface of the tailing ponds dries up, it leads to dust storms, which often cover housing areas of the city as well as surrounding villages. To green these tailing ponds is one of the most reliable methods of dust suppression. However, the solving of this problem is fraught with a number of difficulties because very restricted quantity of herbaceous plant species can survive in the sludge substrate under conditions of the steppe zone of Ukraine
