Ecology


Habitat

In southeastern Europe, ''H. pomatia'' lives in forests, open habitats, gardens, and vineyards, especially along rivers, confined to calcareous substrate. In Central Europe, it occurs in open forests and shrubland on calcareous substrate. It prefers high humidity and lower temperatures, and needs loose soil for burrowing to hibernate and lay its eggs. It lives up to 2100 m above sea level in the Alps, but usually below 2000 m. In the south of England, it is restricted to undisturbed grassy or bushy wastelands, usually not in gardens; it has a low reproduction rate and low powers of dispersal.

Juveniles hatch after three to four weeks, and may consume their siblings under unfavourable climate conditions. Maturity is reached after two to five years. The life span is up to 20 years, but snails die faster often because of drying in summer and freezing in winter. Ten-year-old individuals are probably not uncommon in natural populations. The maximum lifespan is 35 years. During

s and drainage, usually less threatened by commercial collections. Many unsuccessful attempts have been made to establish the species in various parts of England, Scotland, and Ireland; it only survived in natural habitats in southern England, and is threatened by intensive farming and habitat destruction. It is of lower concern in Switzerland and Austria, but many regions restrict commercial collecting.


Cultivation

In Japan, the Mie Escargot Farm succeeded in the complete cultivation of Burgundy species (Pomatia).


Uses

The intestinal juice of ''H. pomatia'' contains large amounts of aryl, steroid, and glucosinolate sulfatase activities. These sulfatases have a broad specificity, so are commonly used as a hydrolyzing agent in analytical procedures such as chromatography to prepare the sample for analysis.
