At the other extreme, the area utilized by urban raccoons has been documented at less than 0.1 km . Generally, home ranges of individual raccoons overlap, and there is little evidence of territoriality, especially in urban areas. As with home ranges, raccoon densities vary significantly depending on the type of habitat. In urban areas, exceptional numbers of raccoons as high as 100 per square kilometre have been recorded. However, densities as low as 1 per square kilometre may occur in prairie habitat.
Raccoons are able to live in a diversity of habitats.
The only apparent requirements are a source of water, food, and a protected area for denning. The best habitats are hardwood swamps, floodplain forests, fresh- and saltwater marshes, and farmland, both cultivated and abandoned. On the prairies, raccoons are most abundant in woodlot and wetland areas. This highly adaptable animal is also very common in many cities of North America. An annual moult of the fur begins in the spring and lasts about three months.
