Snails do not survive rapid and drastic climatic changes. They may then be the nucleus from which a new population is able to develop once more normal conditions return. Saving the terrestrial malacofauna for the future Although it will not be possible to control climatic changes in the future, many of the detrimental factors mentioned above may be reduced if proper actions are taken. One of these will be the strict adherence to a quarantine system to avoid introduction of other new exotic competitors or predators of snails into the islands. An effective control of introduced vegetal plagues is also important, as any modification of the native forests may induce more changes in the microclimates and microhabitats and therefore reduce the ability of snails to survive.
Habitat rehabilitation is a key factor, mainly in the humid forests in the highlands.
It is possibly the most effective effort that could be taken to save snails and many other invertebrates species for the future. This is obviously not an easy task and may include buying land in well chosen areas of the colonized zones in order to protect and develop remaining patches of native forests. Places where snails are still living must be protected first, and control of adequate conditions of life must be made. Some observations have already been done in the field and will be continued in the future. Captive breeding may be a good solution to preserve some of the species for the future.
