The site consists of the lower and middle courses of the River Traun, a tributary of the Danube, and neighbouring areas of gravel-pits and fish-ponds. Substantial areas of riverine forest remain along the middle course of the river. Surrounding arable land is increasingly being put into set-aside. The area is very popular for recreation, primarily watersports and angling.
An important site for breeding species associated with a mix of wetland and forest. The gravel pits hold a large breeding population of Riparia riparia (800-1,700 pairs).
Pressure/threats to key biodiversity
Forested areas are threatened by conversion to arable land, forestry plantations and gravel-pits. A new power plant is under construction within the IBA. The erection of high-tension power-lines has been detrimental to large migrant birds. There is a high degree of disturbance from recreational use of the area.
