ST. HELENA ENDEMIC INVERTEBRATES PROJECT
St Helena is small, rugged 47 sq mile island in the Atlantic ocean, with a population of 4500, and it is a UK overseas territory.
Rarity: St Helena has over 420 endemic invertebrates, this a third of the UK's unique biodiversity on one tiny island. It includes the fantastical Spiky Yellow Woodlouse (pictured), which glows in the dark.
Causes of decline: St Helena invertebrates are threatened by invasive plant and invertebrate species, and the destruction and degradation of their habitats.
