アッツェンブルークの天然記念物・トップ20

ニーダーエスターライヒ州トライズマウアーにあるトライズ川の河口は、技術と自然がどのようにうまく調和できるかを示す魅力的な例です。ここではトライズ川がドナウ川に合流しますが、かつては今日ほど牧歌的ではありませんでした。元々、トライズ川は約7.5キロメートル上流で合流していました。1970年代にドナウ川のアルテンヴェルト水力発電所が建設されたことで、すべてが変わりました。発電所のためにドナウ川の水位が上昇したため、トライズ川は自然に流れ出ることができなくなりました。そのため、まったく新しい川床を掘削する必要がありました。

ここは、70以上のショウガーデンを備えたヨーロッパ初の環境ガーデンショーです。特に人気の高いツリートップウォークからは、トゥルナーフェルト（Tullnerfeld）の素晴らしい景色を眺めることができます。

Idyllic place and lovely time

It's a pity that there is no catering here anymore😌

At approximately 12.5 kilometers, the Altenwörth Fish Bypass is the longest of its kind in Austria and was built between 2019 and 2022 as part of the LIFE Network Danube Plus project. It allows fish such as huchen, schied, and zingel to bypass the Altenwörth Danube power plant and provides a continuous connection to the tributaries, the Kamp and Krems. The near-naturally designed bypass stream, with shallow water zones, gravel banks, and deadwood, also creates new habitats for numerous animal and plant species. The facility is also of interest to cyclists: Along the Danube and its adjacent waterways, natural paths offer views of renaturalized landscapes, small bays, and ecologically valuable rest areas. It is a successful example of how flood protection, energy use, and biodiversity can be reconciled.

One of Austria's longest fish bypasses was created between Altenwörth and Greifenstein as part of the "LIFE Network Danube Plus" project. The approximately 12.5-kilometer-long, near-naturally designed bypass stream allows fish such as huchen, zebrafish, and schied to migrate freely along the Danube and connects important habitats in the tributaries of the Kamp and Krems. Between 2019 and 2022, approximately 34 hectares of new aquatic areas were created, featuring shallow water zones, gravel banks, and deadwood areas – also for kingfishers, otters, and other protected species. In addition to its ecological benefits, the area is now also attractive to recreational travelers: Along the waterway corridor, natural banks, small bays, and viewpoints invite visitors to linger – a successful example of the combination of nature conservation, water development, and sustainable tourism.
