What is a significant impact of muskrat overpopulation in aquatic environments?

The significant impact of muskrat overpopulation in aquatic environments is the loss of shoreline stability. Muskrats are known to create extensive burrowing systems along the banks of rivers and ponds, which can lead to increased erosion. This erosion destabilizes the shoreline, causing soil and vegetation to wash away, resulting in altered habitats for both aquatic and terrestrial species.

Maintaining shoreline stability is crucial for preventing sediment runoff, preserving aquatic plant life, and providing habitats for various organisms. An overpopulation of muskrats can disrupt these essential ecological functions, ultimately leading to degraded water quality and diminished biodiversity in the area.
