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. 

​Threats to the endemic invertebrates of St Helena, include:

  • Invasive species, including introduced plants and animals 

  • Loss and fragmentation of native habitat, the habitats on island are very unique but they are vulnerable with increasing population pressures, these areas are getting smaller, further apart and more degraded

  • Development on a small island where tourism is increasing, what looks like boring habitat can contain many endemics

  • Climate change impacts

The Species Recovery Trust is supporting projects on St Helena's endemic invertebrates, including via the Invasive Invertebrate Project DPLUS104 and the wider Cloud Forest Projects. Providing specialist invertebrate advice, conservation planning skills and increased capacity for conservation delivery.
