Snail Rescue: A Tiny Victory in Island Ecology

The story of Partula snails shows how small creatures can teach big lessons about nature and human care.

• 1980s – A harmful snail was introduced to French Polynesia to combat another pest.
• Outcome – Instead of helping, it preyed on native Partula species, pushing them close to extinction.

A Bold Rescue Mission

In 1991, a team led by the Zoological Society of London launched an ambitious plan:

• Captive breeding: Snails were bred in zoos.
• Reintroduction: Thousands of individuals were released onto four islands.

This effort is the largest of its kind, moving over 7,000 snails into protected areas.

Why They Matter

• Experts compare the Partula to “Darwin’s finches”: small, rapidly evolving, and highly adaptable.
• Their study provides a live window into how isolation shapes species over time.

A Model for the World

The initiative is praised as a model for protecting fragile island ecosystems worldwide.
