Acacia anegadensis (poke-me-boy)

Few trees are under greater threat from increases in sea level due to climate change than poke-me-boy, found almost exclusively on one of the British Virgin Islands (Anegada), which stands only 8 m above the Caribbean Sea.

About this species

Until recently, Acacia anegadensis was known only from Anegada, a low-lying coral limestone island (sometimes called the ‘drowned island’) in the British Virgin Islands (BVI). These Caribbean islands comprise one of the UK Overseas Territories (UKOTs). Taken overall, they are rich in plant diversity, with over 700 native species, but those species which occur only on a single island are particularly threatened by the potential effects of climate change, as they may have very specific habitat requirements. In 2008, one of Kew’s botanists, Colin Clubbe, discovered a small population of poke-me-boy growing on Fallen Jerusalem, another of the BVI, where environmental conditions are different from those on Anegada.
