Increasing our understanding of natural vegetation in the Chagos
A comprehensive task
In 2018, Sara Bárrios and Tim Wilkinson, a botanist and a spatial scientist from the Science Department of the Royal Botanic Gardens Kew, travelled to the island of Diego Garcia with the aim of creating the first comprehensive record of the island’s vegetation.
Once known for its coconut plantations, the vegetation of Diego Garcia is now a complex mix of abandoned plantation sites gone wild, and areas where native plant species still dominate.
A blooming success
Prior to this field trip only very limited plant survey data was available. Now, having used a suite of different survey techniques, the team surveyed the whole island and its various habitats.
Expedition key aims
Recording vegetation every mile by dividing the islands into areas, using a traditional survey approach. This botanical data is available online via Kew’s Online Herbarium（https://www.kew.org/science/collections-and-resources/collections/herbarium）.
