Frequently asked questions

How many threatened species are in Seychelles?
Seychelles has 463 threatened species recorded on SpeciesRadar — 117 of those are Critically Endangered, facing an extremely high risk of extinction. The figures combine IUCN Red List data with national red list assessments where available.
How many Critically Endangered, Endangered, and Vulnerable species does Seychelles have?
Of the 463 threatened species in Seychelles, 117 are Critically Endangered, 209 are Endangered, and 137 are Vulnerable. Together these three IUCN Red List categories make up the "threatened" total.
What is the most endangered species in Seychelles?
Among the 117 Critically Endangered species in Seychelles, Astropanax procumbens is one of the most at-risk — featured prominently on the country dashboard. The full list of Critically Endangered species is filterable on the Species tab.
What protected areas exist in Seychelles?
SpeciesRadar does not yet catalogue protected areas for Seychelles. Where available, protected-area data is drawn from the World Database on Protected Areas (WDPA) and national designations.
Which animal and plant groups are most threatened in Seychelles?
The most affected groups in Seychelles, by number of threatened species, are arachnids (136), plants (60), and insects (53). The full taxonomic breakdown is shown on the country dashboard.
What are the biggest threats to wildlife in Seychelles?
The leading threats to threatened species in Seychelles are invasive non-native/alien species/diseases, habitat shifting & alteration, logging & wood harvesting, and fishing & harvesting aquatic resources. Each threat is mapped to the species it affects in the country's threat breakdown.
How many threatened species are found only in Seychelles?
Seychelles has 318 threatened species that are endemic — found nowhere else on Earth. Because their entire global population depends on this one country, they are especially vulnerable to local habitat loss.
How many of Seychelles's threatened species have declining populations?
140 of Seychelles's threatened species have populations that are still declining. Reversing these trends is the central focus of the conservation work the country dashboard tracks.
How does Seychelles compare to other countries for threatened species?
Seychelles ranks #76 of 250 countries by number of threatened species, and accounts for roughly 0.83% of all threatened species tracked worldwide. Threat is geographically concentrated, so a high rank reflects both rich biodiversity and intense pressure on it.
Where does the data for Seychelles come from, and can I download it?
SpeciesRadar draws on the IUCN Red List, the Global Biodiversity Information Facility (GBIF), the World Database on Protected Areas, and national red lists. Every table on the Seychelles profile — species, national red list, and protected areas — can be downloaded as a CSV spreadsheet or a branded PDF report.
