Beavers were recently reintroduced in my country to help the ecological system develop. All I know is that they build dams, which I would assume isn’t very good for river fish. I also just learned they tend to eat/use young trees, which can’t be good for the forest growth. How do they actually benifit the ecological system?

Basically, their dams end up regulating the water, keeping nutrient-rich soil in the river system, and creating small ponds that massively help most native river fish.
