This species is rated as special concern in Wisconsin meaning that some problem of abundance or distribution is suspected but not yet proven. The main purpose of this category is to focus attention on certain species before they become threatened or endangered (DNR, 2009). To read more follow link.

This species is found in wooded calcareous or igneous outcrops, limestone/lakeshore ledges, and on bark on hard wood grooves. Vertigo bollesiana is also found in leaf litter on wooded hillsides and in marshes (Burch, 1962). The range of this species includes southern Ontario, north to Lake Temagami. In the United States this species is known in Indiana, Iowa, Kentucky, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New York, North Carolina, Ohio, Tennessee, Virginia, West Virginia, and Wisconsin (Pilsbry, H. 1948). I have provided a map to make it easier.


This species does not respond well to disturbance and seems to be limited to sites which have not been disturbed for at least 100 years (Nekola, J. 2003). Vertigo bollesiana has been found to inhabit algific and manderate sites. Threats include physical filling of upland sinks with trash or soil, discharge of agricultural pollutants such as pesticides, herbicides and fertilizers, grazing, human traffic, removal or clearing of vegetation, road building, quarrying. Rock climbing is minor but a real problem on some specific sites (Nekola, J. 2003).
