Frequently asked questions

How many threatened species are in Taiwan?
Taiwan has 492 threatened species recorded on SpeciesRadar — 78 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 Taiwan have?
Of the 492 threatened species in Taiwan, 78 are Critically Endangered, 196 are Endangered, and 218 are Vulnerable. Together these three IUCN Red List categories make up the "threatened" total.
What is the most endangered species in Taiwan?
Among the 78 Critically Endangered species in Taiwan, 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 Taiwan?
SpeciesRadar does not yet catalogue protected areas for Taiwan. 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 Taiwan?
The most affected groups in Taiwan, by number of threatened species, are fishes (150), corals (101), and plants (100). The full taxonomic breakdown is shown on the country dashboard.
What are the biggest threats to wildlife in Taiwan?
The leading threats to threatened species in Taiwan are fishing & harvesting aquatic resources, logging & wood harvesting, annual & perennial non-timber crops, and type unknown/unrecorded (pollution). Each threat is mapped to the species it affects in the country's threat breakdown.
How many threatened species are found only in Taiwan?
Taiwan has 53 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 Taiwan's threatened species have declining populations?
333 of Taiwan'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 Taiwan compare to other countries for threatened species?
Taiwan ranks #75 of 253 countries by number of threatened species, and accounts for roughly 0.88% 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 Taiwan 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 Taiwan profile — species, national red list, and protected areas — can be downloaded as a CSV spreadsheet or a branded PDF report.
