The suggested area of the European protected area “Machland Nord” extends from the power station Wallsee-Mitterkirchen in the west to the borders of the Danube near Hirschenau. In the south, the frontiers to Lower Austria form the borders. In the north, the eastern part is defined by the northern Danube banks and near Dornach the terrace edge to the lower terrace forms the borders.
Approaching the power station Wallsee-Mitterkirchen, the „Hüttinger Arm“ is the northern border of the area.
Near the lower terrace the floodplain forest is loosen up by arable land and meadows. The predominantly forestry dominated riparian forest has remnants of white willow floodplains and numerous alluvial waters. Intensive agricultural use and a low proportion of forest characterize the lower terrace. At the acclivity of the low terrace, from a nature protection point of view, the most valuable habitats are situated: rough pastures and semiarid grasslands. In the lowlands of the left banks feeder Aist, Narn and Mettendorf’s Mühlbach exists a mosaic of forest residues and agricultural land
