The area was used as small-scale ploughland and vineyards between app. 1900 and 1960. From 1960 it was gradually abandoned and became a part of the Kiskunsag National Park. We distinguished 4 age-groups of old-fields according to the time of the abandonment: 1–6, 7–11, 12–25 és 26–35 years old abandoned fields in year 2000. In every age-group 10–10 (total 40) 4 m × 4 m large permanent vegetation survey plot were established. We made vegetation survey (presence and cover of every vascular plant species) in the year 2000, 2008, 2010, 2015, 2017 and 2020.

GIS thematic data on human activity and infrastructure in the Park, covering a.o. (1) tourism infrastructure and activity (trails, shelters, campsites, caves accessible to tourists, museums, sports and leisure infrastructure, educational facilities, etc. - as well as tourist traffic counts); (2) roads and other transport facilities (incl. cable car); (3) buildings (dense housing and individual objects), (4) geodetic/cadastral layers, land parcels, (5) cultural heritage (historic monuments incl. religious objects, remnants of past mining activity, historic sheep/cattle grazing infrastructure such as shepherd huts, etc.); (6) other infrastructure (e.g. power lines, water takeup points, meteo stations, etc.). Also, data on anthropogenic pressure: environmental impact and damage of human activity available.
