Discovering New Guests in Berlin's Graveyards: The Edged Snail Arrives
It seems Berlin's graveyards have welcomed a new resident, likely hailing from Southern Europe. This uninvited guest is none other than theedge snail (Hygromia cinctella), as revealed in a study by the Museum für Naturkunde Berlin. The researchers suggest that the snail species is set to expand its territory in the area soon. According to their report, the snails might have found their way into Berlin through innocent human activities, such as transporting plants or soil.
The sighting of these snails in Berlin hadn't been documented before in the scientific literature, but there have been whispers from locals indicating their presence since 2019, even in Brandenburg. The edge snail has now made its presence known in the Wilmersdorf and Buschkrugallee (Neukölln) cemeteries, where the researchers also discovered many empty shells, likely due to rodents and beetles.
As established in the Wilmersdorfer Strasse Neukölln cemetery, the edge snail can be easily distinguished by its characteristic, often white-banded edge, approximately 1 cm wide. Despite the edge snail being classified as foreign, there's no clear evidence yet that it negatively impacts native ecosystems. However, it might compete with native species or possibly displace them.
Originally thought to have originated from Italy, this snail species spread to various parts of Europe, with Germany being one of the latecomers. In fact, the first recorded sighting in Germany was in Bavaria, back in 1995. Recent research has verified its presence in cemeteries around Berlin. Over 200 cemeteries in Berlin have the potential to serve as crucial refuges for biodiversity.
The study, published in the portal Neobiota-Nord, concentrated on investigating four Berlin cemeteries through search and soil sample processes. Check out the for more details.

As more native and non-native species join the vibrant urban landscape, the importance of conserving biodiversity in our cities grows exponentially. The appearance of non-native species such as the edge snail in Berlin underscores the need for informed ecological studies.
The spread of the edge snail beyond Berlin's cemeteries paves the way for intriguing research in the fields of urban ecology and conservation. Future research should examine the interactions between the edge snail and native species, as well as evaluate the overall effects on Berlin's urban biodiversity.
The presence of the edge snail in Berlin's Southern European-influenced cafes and restaurants might introduce an unexpected twist to the local food culture – after all, who knew we shared our environment with the small, intriguing creatures?
Beyond the Base Article: In-depth
The spread of the edge snail raises several questions about its impact on biodiversity. While it's possible that the snail could contribute to the overall diversity of the cemetery ecosystem, its presence might also disturb native species and alter the existing habitat structure.
One of the positive impacts of the edge snail is that it might contribute to the creation of new habitats within the cemeteries. Snails' activities, such as burrowing, can help alter the physical structure of the soil, benefiting other organisms like insects and microorganisms. However, this new habitat might also create challenges for native species that depend on specific conditions, causing displacement or altering the food chain.
Predation, competition for resources, and disease transmission are some of the potential negative impacts of the edge snail's arrival. The introduction of a new species could disrupt ecological niches and harm native species that might not be able to adapt as quickly.
It's crucial to monitor the edge snail's movements and its impact on Berlin's cemeteries and surrounding ecosystems to determine its overall contribution to the city's urban biodiversity. By staying informed on the effects of non-native species in urban environments, we can better understand the diversity of our cities and make more informed decisions regarding conservation and management strategies.
