RIVER OTTER, MINK, OPOSSUM, SKUNK, MOUNTAIN BEAVER, NUTRIA, MUSKRAT, ETC.

River Otters/Mink will access crawlspaces and nest their young. They will also get into fish ponds and cause immense damage.
Opossums/Skunks will gain access to chicken coops, crawlspaces, and other small dwellings.
Mountain Beavers dig large tunnels in gardens and other landscapes. They can also eat valuable plants/crops, sometimes causing immense damage to the branches/leaves of rhododendrons.
Nutria/Muskrats create burrows in the banks of ponds, streams, lakes, and rivers. This eventually leads to erosion and other issues.
