One year after the complet emptying of the reservoir, the Selune river is already welcoming its new inhabitants. Jean-Marc Rousel from INRA tells us “1km upstream the former Vezins dam the river is breathing vigorously now, incredibly rich in habitats and many invertebrates species (stone flies, caddis flies, dragon flies…) and some fish too! In particular the Sculpin (Cottus gobio) has returned from upstream. The invasive American crayfish is also spreading from downstream… but its upcoming predator, the European eel, is waiting for its turn, below the second dam (La Roche-qui-boit), ready for ascending…”.
