Snails are often seen as pests when found in gardens (Land Snails, FOSS, 2011).  Their hard shells protect them from predators, along with their ability to retract into the shell (Land Snails, FOSS, 2011).  The status of the Patera roemeri snail, as far as whether it is endangered or not, has not been researched (Discover Life, 2012).
