Most interesting landmarks of Ascension Island

Ascension Island is a part of British Overseas Territory of Saint Helena. This remote island is neither part of Africa nor South America – but in order to keep files in some order, Wondermondo lists Ascension Island as a part of Africa.

Rather many species of animals and plants are met only on this remote island and in the sea waters around it.

The indigenous plants and animals of this island have been heavily affected by introduced species of plants and animals, but some have survived. There are the following endemic plant species (all endangered):

  • fern Anogramma ascensionis
  • fern Asplenium ascensionis
  • spurge Euphorbia origanoides
  • fern Marattia purpurascens
  • fern Pteris adscensionis
  • grass Sporobolus caespitosus
  • fern Xiphopteris ascensionense

Several species of fish (including Taenioconger camelopardalis and Helcogramma ascensionis) along the shores of the island are not met anywhere else. Endemism among the smaller animals – insects and crustaceans – is higher, f.e. 14 species of decapods are met only here. All 5 species of pseudoscorpions are endemic.
