What disadvantages do otters have if all the reeds were removed from riverbanks?

If all the reeds were removed from riverbanks, otters would face several disadvantages. Reeds provide crucial habitat for otters, offering protection from predators and a place to rest. Without reeds, otters would be more exposed and vulnerable to threats. Additionally, reeds are important for stabilizing riverbanks and maintaining water quality, so their removal could have broader ecological impacts on the otters' environment.
