Frequently asked questions

How many threatened species are in Micronesia?
Micronesia has 126 threatened species recorded on SpeciesRadar — 17 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 Micronesia have?
Of the 126 threatened species in Micronesia, 17 are Critically Endangered, 64 are Endangered, and 45 are Vulnerable. Together these three IUCN Red List categories make up the "threatened" total.
What is the most endangered species in Micronesia?
Among the 17 Critically Endangered species in Micronesia, Giant Clam (Tridacna gigas) 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 Micronesia?
SpeciesRadar does not yet catalogue protected areas for Micronesia. 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 Micronesia?
The most affected groups in Micronesia, by number of threatened species, are corals (49), fishes (24), and birds (14). The full taxonomic breakdown is shown on the country dashboard.
What are the biggest threats to wildlife in Micronesia?
The leading threats to threatened species in Micronesia 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 Micronesia?
Micronesia has 28 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 Micronesia's threatened species have declining populations?
87 of Micronesia'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 Micronesia compare to other countries for threatened species?
Micronesia ranks #168 of 250 countries by number of threatened species, and accounts for roughly 0.23% 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 Micronesia 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 Micronesia profile — species, national red list, and protected areas — can be downloaded as a CSV spreadsheet or a branded PDF report.
