Upper Austria

All Upper Austrian spatial units

The Inntal is one of the 41 Upper Austrian spatial units and is located in the Innviertel along the Inn River. It comprises the Austrian parts of the Lower Inn.

Location

The spatial unit is located in the districts of Braunau, Ried and Schärding.

The area of the Inn Valley is about 231 km² and extends over about 60 km. The width varies between 200 meters and 9 km. The lowest area is at about 312 m a.s.l. near Schärding. The highest area of the region is near Fuchshofen at 406 m abovesea level.

The following municipal areas have a large share of the Inntal (arranged alphabetically by district): Altheim, Braunau, Burgkirchen, Mining, St. Peter/Hart, Überackern, Weng, Antiesenhofen, Geinberg, Kirchdorf, Mörschwang, Mühlheim, Obernberg, Reichersberg, St. Georgen/Obernbg, St. Martin/Innkr., Schärding, St. Marienkirchen/Schärding, St. Florian/Inn, Suben and Wernstein.

The spatial unit is surrounded by the following Upper Austrian spatial units (clockwise, starting in the north)
Danube gorge and side valleys, Sauwald, Inn and Hausruckviertel hill country, Mattigtal, Neukirchner Platte, Weilharts and Lachforst and Salzach Valley.

The Inn valley is divided into four subunits:

  • Inn and riparian forests
  • Low terrace with cultural landscape
  • Terraced landscape
  • Slope forests

Characteristics

  • Wide valley lowland on the right bank of the Inn with floodplain forest and chain of power stations.
  • The riparian forests consist mostly of grey alder, silver willow and ash. They are an important waterfowl area and there is a stable beaver population. There are conflicts between anglers and conservationists over the bird sanctuary. The riparian forests also occur outside the power plant dams (e.g. near Mining and Kirchdorf).
  • The cultural landscape between Mühlheim and Hagenau has many structural elements. Numerous hedges, small forests, orchard meadows and marshes can be found. Furthermore, there are small settlements in this subunit.
  • The slope forests are near-natural forests with ash, maple, beech, oak and hornbeam. There are also many small streams and ponds here.
  • Flowing waters from the adjacent hill country are often regulated in the Inntal. The Antiesen flows through a gorge up to 40 metres deep with Schlier walls.
  • The high and low terraces are intensively used for agriculture. This area is covered with loess, the proportion of forest is less than 4%.
  • The settlement areas lie along the edges of the terraces and dense development exists only in Braunau. The numerous castles and monasteries (e.g. Reichersberg Abbey) are characteristic of the landscape.
  • Traffic routes (e.g. Innkreis motorway) cut through the area.
