How can we better understand and protect them? #Vigilife has launched the #30sentinelrivers program with #eDNA. A thread 1/n By building an international network of partners and sharing #eDNA know-how, #Vigilife is establishing long term #monitoring programs, which will become a precious tool for safeguarding freshwater biodiversity.
