Habitat

Vertigo nylanderi is a rare species with particular taste in habitat and as a result is only found in a relatively small region in North America. It is found in areas with calcareous substrates from Northern and Eastern Main to Northwestern Minnesota (Nekola and Massart 2000). The ideal soil appears to have a thin layer of organic material such as fallen leaves over firm ground held together with plant roots (Lee 2007). When found in Wisconsin and Michigan it tends to be within 40 kilometers of a large body of freshwater (i.e. Lake Michigan or Lake Huron). The majority of the time they are found in wooded wetlands where White Cedar, Tamarack, or Black Ash trees are abundant, but can occasionally be found in low grasslands (Nekola 2002). The largest known population of Vertigo nylanderi is in Eastern Maine.
