Land snails, semi-slugs and slugs are important players in the forest decomposition process and contribute to the nutrification of soils through their decaying bodies, shells and faeces. Their dead shells can form an important source of calcium for other animals in calcium-poor habitats.
Land snails recycle forest nutrients and are prey for a number of vertebrate animals as well as other invertebrates including carnivorous snails. And their dietary preference for fungi may also be a factor in fungal spore dispersal.
Land snails are important environmental indicators and biodiversity predictors and have role to play in the monitoring of climate change. Their conservation should be a high priority.
