Muskrats Overview
Muskrats are medium-sized, semi-aquatic rodents recognized for their dense fur, laterally flattened tails, and webbed hind feet, adaptations that make them excellent swimmers. Inhabiting wetlands across Tennessee and South Carolina, muskrats are crucial for maintaining healthy aquatic ecosystems. They build lodges and burrows along waterways, which can alter the water’s flow and provide habitats for other species. While generally beneficial, muskrats’ burrowing habits can compromise levees, dikes, and agricultural lands, sometimes necessitating control measures.
Muskrat Burrows and Lodges
Muskrats are known for constructing elaborate systems of burrows and lodges, which serve as shelters and protection against predators. Burrows are dug into the banks of rivers, ponds, and lakes, with underwater entrances that lead to above-water living chambers. Lodges are built from vegetation and mud in the water, creating dome-shaped structures that are visible above the surface. These constructions are crucial for muskrat survival and reproduction but can sometimes cause issues for human infrastructure, such as erosion and flooding, due to their impact on water flow and bank stability.
Muskrats Diet
Muskrats primarily feed on aquatic vegetation, such as cattails, water lilies, and rushes, playing a significant role in controlling the growth of these plants in wetlands and waterways. They also eat crops like corn and soybeans when living near agricultural fields, which can lead to conflicts with farmers. In addition to plants, muskrats occasionally consume fish, shellfish, and amphibians, showcasing their adaptability to available food sources in their habitats.
Muskrat scat provides an indicator of their presence and diet in aquatic environments. The droppings are typically small, tubular, and contain bits of plant material, reflecting their herbivorous diet. Scat is often found near feeding sites or within muskrat lodges and burrows. Identifying muskrat scat can help in monitoring their populations and the health of wetland habitats, as well as in managing their impact on human-made structures and agricultural areas.

Muskrats Tracks
Muskrat tracks are an interesting feature to observe, especially near wetland habitats where these animals are active. The tracks typically show four toes on the front feet and five on the back, with slight webbing visible on the hind feet, which aids in their swimming. The front tracks are smaller and less distinct than the hind tracks, which can leave a more pronounced impression in soft mud or sand along the water’s edge.
Muskrat tracks often lead to and from water bodies, indicating the pathways these animals use to travel between feeding areas, burrows, and lodges. In snow or mud, besides the footprints, you might also see drag marks from their tails, adding a distinctive trail to the prints. Recognizing muskrat tracks can provide valuable insights into their presence and movement patterns, aiding in the understanding and management of their populations and the ecosystems they inhabit.
