According to the Nature Conservation, the snails most likely arrived on their grounds more than 100 years ago on stones imported from Italy and Greece. Since then the snails have only populated a small area, but the Nature Conservation is conducting a search to see if the snails have populated anywhere else. They are asking the public to be on the look out for the snail.
It doesn't seem as if the snail has any negative impact on the environment in terms of disturbing the food chain or causing any other disruptions, but I still find it strange that finding the invasive species seems to be more of an oddity than a concern. I also find it strange that it took over 100 years for anyone to notice the snail where it wasn't supposed to be.
