Hungary's first national park, Hortobágy National Park, encompasses roughly 72 square miles (115 km2) of almost completely flat saliferous, semi-arid grasslands, pockmarked with rivers, lakes and wetlands containing remarkable biological diversity of plant and animal species and habitats. This landscape has been primarily shaped by water, mainly by the huge floods of the River Tisza which once seasonally covered this part of Hungary rejuvinating the region.
