The oribatid faunae at 248 sampling points in 13 mires in northern Japan were surveyed with the object of establishing a method of assessing environmental change on wetlands using the occurrence of oribatid mites. Analysis of the general and characteristic features of oribatid fauna in the localities confirms that oribatid mites are overwhelmingly the dominant animal group in wetlands. There were 14 common genera in these localities: Limnozetes, Trimalaconothrus, Oppiella, Malaconothrus, Liochthonius, a member of the Suctobelbidae, Atropacarus, Trhypochthoniellus, Ceratozetes, Nanhermannia, Tectocepheus, Nothrus, Hoplophthiracarus and Hydrozetes. The most characteristic oribatid mites were the two genera Limnozetes and Trimalaconothrus, which were both common and dominant in most localities. The fauna in each locality was uniquely characterized by combinations of particular genera, including Platynothrus, Hydrozetes, Hypochthoniella, Parachipteria, Diapteroabates.
