Flood detention basin Stillbach

This project shows with the right construction of the base layer, the adjusted greening techniques and the a site specific seedmixture an extensive, high valuable ecological meadow is possible. The flood detention basin was built in cooperation with the nature conservation department of Upper Austria and the Agricultural Research and Education Centre Raumberg-Gumpenstein (AREC). The demonstration site is also part of the Salvere Project and the applications of the seedmixtures from High Nature Value Farmland will be tested. For the construction of the flood detention basin different types of gravel are used as well as different seedmixture combinations. The area was sown via hydroseeding, consisting of a mixture of seed-rich material from on-site threshing of commercially propagated species from regional origin. The seed rich material from on site threshing was originated from the Welser Heide. The different samples of seed mixture are

• Sample area I semi dry grass and mixture (AV1)
• Sample area II poor grass and mixture (BM1)
• Sample area III Tall oat grass meadow (AV2)
