Ornithological information 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).
Site description 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.

Management considerations 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.
Protection status National Low International High75 ha of IBA covered by Nature Reserve (Fischlhamerau, 75 ha). 2,100 ha of IBA covered by Special Protection Area (Unteres Trauntal, 2,100 ha).
