Is beavers build a dam on the stream the kinds of plants and animals that lived around the stream would not be affected?

When beavers build a dam on a stream, it significantly alters the local ecosystem, affecting both plants and animals. The dam creates a pond, which can change water levels, temperature, and sediment distribution, thereby impacting the types of vegetation that can thrive in the area. Aquatic species may benefit from the new habitat, while some terrestrial species may struggle with the altered landscape. Overall, the construction of a dam has a profound effect on the surrounding flora and fauna.
