Colleagues from our lead partner, the Budapest University of Technology and Economics, recently visited the iNNO SED demonstration site along the Iller River in Southern Germany.
The Iller is heavily fragmented and regulated by hydropower dams, disrupting sediment transport, gravel replenishment, and spawning habitat quality.
Here, they were especially fortunate to witness fish spawning along the river shore! Seeing the fish excavate spawning redds with intense tail movements in the restored gravel bed was perhaps the clearest sign that the habitat is becoming functional again 
You can see some of the action in the video below (watch out for occasional splashes!).
Our partners at BME have started a small new tradition: collecting sediment samples from iNNO SED demonstration sites and associated regions across Europe 
Below are a few more photos from the fieldtrip!
