Frequently asked questions

How many threatened species are in Palau?
Palau has 208 threatened species recorded on SpeciesRadar — 33 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 Palau have?
Of the 208 threatened species in Palau, 33 are Critically Endangered, 117 are Endangered, and 58 are Vulnerable. Together these three IUCN Red List categories make up the "threatened" total.
What is the most endangered species in Palau?
Among the 33 Critically Endangered species in Palau, Diplommatina alata 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 Palau?
SpeciesRadar does not yet catalogue protected areas for Palau. 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 Palau?
The most affected groups in Palau, by number of threatened species, are corals (112), molluscs (35), and fishes (31). The full taxonomic breakdown is shown on the country dashboard.
What are the biggest threats to wildlife in Palau?
The leading threats to threatened species in Palau are habitat shifting & alteration, fishing & harvesting aquatic resources, invasive non-native/alien species/diseases, and annual & perennial non-timber crops. Each threat is mapped to the species it affects in the country's threat breakdown.
How many threatened species are found only in Palau?
Palau has 39 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 Palau's threatened species have declining populations?
150 of Palau'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 Palau compare to other countries for threatened species?
Palau ranks #132 of 250 countries by number of threatened species, and accounts for roughly 0.37% 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 Palau 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 Palau profile — species, national red list, and protected areas — can be downloaded as a CSV spreadsheet or a branded PDF report.
