Terrestrial molluscs: Major Threats

The most significant threat to terrestrial molluscs is the destruction of suitable habitats through urbanisation; the increasing overflow of settlements and related infrastructure into the countryside. This problem is amplified in islands with only limited space. The second most important threat is agriculture, which alters basic environmental factors leading to a decrease in habitat quality. In addition agriculture increases the isolation of remaining non-arable land patches, thus contributing to reductions in species richness. In third place are recreational activities, particularly in coastal and alpine areas, which are transformed and over-used due to tourism. In the future wild-fires could have a significant effect on terrestrial snails, particularly in the Mediterranean region.
