KISKUN LTER was established in 1995, together with the Hungarian LTER Network. Its study area is the Kiskunság Sand Ridge and its periphery, 14000 km2 altogether, 17% of the area of Hungary. The primarily sandy area is extremely heterogeneous. It consists of arable lands, planted forests, meadows, abandoned fields, settlements, alkaline lakes, wetlands, and species rich remnants of forest steppe. It is also very varying in time: ploughing and setting aside, extensive plantation of alien trees, drainage, wild fires, biological invasions, and fast demographic movements have been happening in the last 100 years, and beyond all those, the area is particularly sensitive to the climate change.

Purpose of Site :

KISKUN LTER aims to study the living environment, to detect and monitor its changes, to understand and model the underlying causes and mechanisms, and to use the knowledge acquired to help preserving the biodiversity and associated ecosystem services. The major actor behind the changes is the human being, the the quality of the changed living environment impact the quality of the human life. We study the living environment and its ecological processes embedded into the social and economical environment. Major topics: organization and structure of the sand grassland; climate change simulation field experiment on sand grassland; spontaneous regeneration of vegetation after agricultural field abandonment and fire; recent changes in ecosystem services due to changes of water availability; restoration of high diversity vegetation.

Geology:

The parent materiel of Kiskunság is Quaternary sediment of Danube river mostly consists of sand. The surface is Holocene, shaped by wind, resulting in well classified (i.e. coarse) sand.

Hydrology:

The ground water level is higher than the level of the surrounding Danube and Tisza river, most probably because of the communicating vessels effect of the Carpathian Mountains. The ground water is slightly and varyingly alkaline. There are undulating surfaces and sand dune systems, where the depressions might be close to ground water. There are extended areas under ground water effect, as well as a shallow freshwater lake, and plenty of temporarily drying alkaline lakes with surrounding alkaline wetlands. In the 1970s, a regional draining system had been installed, and then the groundwater table level dropped one to eight meters. Many of the former wetlands dried out, and most of the alkaline lakes disappeared in the Kiskunság Sand Ridge, i.e. in the muddle part of the area, while other lakes and wetlands remained at the margins of the ridge.
