These pea-sized mollusks, once thought to be extinct, were bred in captivity and are now being monitored for their adaptation and survival in their natural habitat after invasive species destruction prompted their rescue.
Conservation Triumph: Endangered Snails Reintroduced to Remote Island

Conservation Triumph: Endangered Snails Reintroduced to Remote Island
1,329 tiny, critically endangered snails have been successfully released into the wild on a remote Atlantic island, marking a significant step in conservation efforts.
Paragraph 1:
In a remarkable conservation achievement, over 1,300 critically endangered snails have been reintroduced into the wild on a remote island in the Atlantic. The tiny mollusks, no larger than a pea, were bred through dedicated efforts at Chester Zoo, and their release represents a vital step in restoring two species of snails that were previously thought to be extinct for the last hundred years.
Paragraph 2:
The initiative came to fruition after conservationists discovered a meager population of these land snails surviving on Deserta Grande island near Madeira. The presence of invasive species such as rats, mice, and goats had severely compromised their habitat. Fortunately, several expeditions carried out between 2012 and 2017 revealed that 200 individuals had managed to survive, prompting a conservation rescue mission at various zoos across Europe.
Paragraph 3:
At Chester Zoo, meticulous care was taken to recreate suitable living conditions for the snails, leading to the successful breeding of 1,329 offspring. These young snails were carefully marked with non-toxic identification dots before their return to a more natural habitat on Bugio Island, a nearby nature reserve where invasive threats have been effectively eradicated.
Paragraph 4:
Dinarte Teixeira, a conservation biologist, highlighted the importance of the color-coded dots which will aid in tracking the snails’ dispersal, growth, and adaptation post-release. This initiative symbolizes a significant stride in a broader species recovery plan, as Gerardo Garcia from Chester Zoo expressed hope that the success of this release may encourage further reintroductions in the upcoming spring.
Paragraph 5:
The snails play a crucial role in their ecosystem, serving as food for native species and contributing to soil health by breaking down organic matter. Conservationists, including Heather Prince from Chester Zoo, emphasized that the restoration of these tiny yet mighty creatures is key to fostering a balanced and thriving natural habitat. As efforts intensify to protect these vulnerable species, the success of this reintroduction signifies hope for biodiversity conservation.
