Mires in the Danubian Lowland (Northern part of the Pannonian Basin) are typically overgrown with common alder (Alnus glutinosa). Similar stands at this location are unfortunately very rare, what is caused by continuous human intervention in landscape and its natural pattern from Early Holocene. Peatland degradation near Pusté Úľany village started in the mid -eighteenth century, what is supported by historical maps. In the previous century a huge peat extraction took place at this specific mire. Despite these anthropogenic changes, there are still some remnants of natural habitats present, mostly dependant on ground water level. Methodology includes historical map's analysis, digital terrain model and vegetation cover mapping. Actual map of biotopes was completed for the current state of the vegetation cover acquaintance. Historical map's analysis revealed changes and development in the vegetation cover as well as the further relevant landscape changes in the mire during drainage system building. The first artificial drainage channel was built in the second half of the eighteenth century. Subsequently, dense system of the drainage channels was built near Továrniky settlement, continuing the drainage of this area for meadows, pastures and arable land acquisition. This wetland habitat was probably one of the largest mires in Slovakia during Holocene. Its area used to be markedly larger and its sedimentary basin presented much more important influence on landscape development. However, the historical sources revealed higher occurrence of common alder in the past, as well as typical xerothermic oak forest in this area. 27 biotopes were identified, from which 13 biotopes was purely human induced. Most of the area is currently abandoned for its own vegetation succession.
