The UK Overseas Territories make an enormous contribution to Britain’s natural heritage. They are spread across the Pacific, Caribbean and South Atlantic and are rich in biodiversity, home to plants and animals found nowhere else on Earth. Yet the remarkable development of these species also makes them vulnerable.

In the last 500 years, travellers have introduced other, less desirable invaders that threaten the survival of native species. That’s why visitors today must take extra care not to spread seeds or import alien animals into these habitats, says TV plant guru Alan Titchmarsh.

In this video, Alan looks at the problem of invasive species and the remarkable conservation work being done in the UK Overseas Territories.

The video was produced for the Royal Society for the Protection of Birds by greentravelguides.tv parent company Wildside UK Productions Ltd.
