Landscape historical and floristical research on the Kettőos-halom Hurgan in Cibakháza, Hungary.

Abstract

The twin kurgans, called "Kettős-halom" is one of the most valuable kurgans in the Tiszazug region. They are situated near Cibakháza village in Jász-Nagykun-Szolnok County. The twin kurgans are prehistoric burial mounds, which were built next to each other. The northern mound has outstanding nature protection significance, because its surface conserved a loess grassland vegetation, which is in a favourable conservation state. The number of the vascular plant species is 117. The kurgan harbours many protected and regionally rare vascular plant species (such as Agropyron cristatum, Artemisia austriaca, Asperula cynanchica, Astragalus austriacus, Elymus hispidus, Ornithogalum brevistylum, Stipa capillata, Veronica austriaca subsp. dentata) typical to dry grasslands. In the 1970s the body of the southern-eastern mound was almost completely excavate. Nowadays there is only a remnan of the former kurgan in its north-eastern side. On the northern kurgan invasive trees (Robinia pseudoacacia) were planted; the expansion of this species threatens the grassland vegetation, especially on the eatern and southern slopes. In the short run it would be necessary cut the forest and establish a buffer zone around the mounds. In the long run it would also be worth reconstructing the original form of the southern kurgan.
