Well that article ended suddenly.
I'm far from an ecologist, but I know beavers can have harmful effects on certain waters. Slowing the stream may impede the movement of fish, allow mosquitos to breed, and give predators more opportunities. Of course, reducing water downstream may have other knock-on effects too.
It seems like there's good reason to perform long ecological studies before doing something like reintroducing beavers to a river.
I know I have read that in North America, reintroducing beaver leads to more wetlands and less fire danger. However, Europe is different. I just thought this was noteworthy.
Europe at one point was covered in beavers as well. They were just wiped off the face of the continent a lot earlier so you don't have the same evidence. I'll promote the book Beaverleand, how one strange rodent made America again if anyone wants to see how amazing beavers are. It's like reintroducing wolves to Yellowstone, the entire ecological web gets stronger. I LOVE BEAVERS.
Water isn't reduced downstream in any sort of consistent way. It slows the flow of water for a short while as the beaver builds its dam, but unless the soil is so parched that the surrounding groundwater basin could absorb significant volumes, the water will keep going after a short stay in the wetlands.
