federal list of endangered, threatened, or candidate species in
the United States (U.S. Fish and
Wildlife Service, 2003). Even though it is not included on
the list, its is still seen as a species that is vulnerable in

There are many activities that have a negative impact on habitat of many land snails. These activities can alter the soil or change the amount of moisture, calcium, food or refuge in the habitats that the land snails occupy (Sterki, 2007). Such activities that cause these problems are timber harvesting, road construction and mining, just to name a few (Sterki, 2007). Vertigo paradoxa, along with many other land snails, have had reduced species and abundance in areas that have had prescribed fire (Sterki, 2007). Rock climbing may also impact this species as it has been found to negatively impact land snail density and diversity (Sterki, 2007).
Timber harvesting is greatly reducing the number of Vertigo
paradoxa.
