The small Caribbean island of Redonda near Antigua and Barbuda provides is a case study for what is possible with well-planned ecological restoration efforts are enacted. Project design and on-the-ground management were keys to this success and the island's tropical environment allowed for rapid recovery to occur.
Collaborations were established between the non-profit Environmental Awareness Group (EAG), Fauna and Flora a Caribbean wildlife organization, and local volunteers who worked together to restore a 'moonscape' on denuded Redonda to become a wildlife sanctuary. Some native species recovered from remnant survivors on the island; some seabirds re-established rookeries; while several other species were specifically re-introduced to their former habitat. The recovery of the island's vegetation, birds, and other wildlife was remarkable. Before and after drone views show the progress of recovery over a six year timeline.

Islands are excellent locations for restoration projects as the represent a contained landscape surrounded by water. An island's ecological degradation typically began with the release, sometimes purposefully in the release of goats, pigs and rabbits for food, or un-intentionally by the escape of rats and cats from ships that stopped there. The invasive animals adapted well to their new environment becoming feral pests that devoured the island's plants, trees, birds, and other wildlife. For restoration to have any chance of success, these invaders must be removed. This can require aerial sharp-shooters to cull the goats and pigs or species-specific viruses that eliminate the cats and rats. Other islands, from California's windy Channel Islands to Australia's sub-Antarctic Macquarie Island, show how rewilding is possible even in extreme environments when a project is planned and executed properly.
The EGA, Fauna & Flora, and their collaborators are working to restore other islands iin the Caribbean degraded by feral pests to repeat their success demonstrated on Redonda. WHB
