Wetlands systems are at the risk to changes in hydrological regime under climatic variation. Wetland habitat is sensitive and responses quick to climate changes. Wetlands cover 6% of the world’s land surface and contain about 12% of the global carbon pool, play an important role in the global carbon cycle (International Panel on Climate Change (IPCC); In a time of global climate change, wetlands conditions are not known well enough. That’s why the research that we have been carried out since couple of years which are based on satellite data and in-situ data are important for depicting the changes in hydrological and vegetation parameters. Biebrza Wetlands are our main area of research, because they are: • one of the largest area in Europe covered with marshes, swamps, and wet meadows • 60 000 ha of flat river valley covered with hydrogenic soils such as peat in various stages of mouldering • habitat of 271 bird species • protected as a National Park, Natura 2000 and RAMSAR sites The results are also connected to serve as an indicator of UN Sustainable Development Goal 6.6.1 - Change in the extent of water-related ecosystems over time.
