|Population:||Often abundant in suitable habitat (e.g. in urban areas).|
|Habitat and Ecology:||This species is present in lowland and coastal regions wherever humans are. It is more common in colder climates (e.g. at higher northern and southern latitudes); in warmer and tropical regions it is restricted to habitats highly modified by humans (sewers, buildings, ports, etc.). It does not compete with R. rattus, as the latter is scansorial/arboreal whereas R. norvegicus is strictly terrestrial.|
|Major Threat(s):||There are no major threats to this species.|
|Conservation Actions:||None in place and none required.|
