British Indian Ocean Territory

The JNCC database lists 230 plant species and 4 mammal species for British Indian Ocean Territory.

Problems with invasive non-native species

Most of the islands in the group are rarely visited but there are black rats (Rattus rattus) on most of the islands and feral cats and donkeys are present on Diego Garcia. Indications are that seabird numbers are significantly reduced on rat infested islands. Marine Toads (Rhinella marina) are also present on Diego Garcia and are regarded as a introduced species of conservation concern. Coco Palms have dominated or replaced native vegetation on a number of islands.

Priority invasive non-native species and actions

There is an ongoing programme of cat eradication on Diego Garcia. A rat eradication project on Eagle Islands in 2006 failed.
