Frequently asked questions

How many threatened species are in Thailand?
Thailand has 1,024 threatened species recorded on SpeciesRadar — 166 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 Thailand have?
Of the 1,024 threatened species in Thailand, 166 are Critically Endangered, 386 are Endangered, and 472 are Vulnerable. Together these three IUCN Red List categories make up the "threatened" total.
What is the most endangered species in Thailand?
Among the 166 Critically Endangered species in Thailand, 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 Thailand?
SpeciesRadar does not yet catalogue protected areas for Thailand. 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 Thailand?
The most affected groups in Thailand, by number of threatened species, are plants (464), fishes (178), and corals (85). The full taxonomic breakdown is shown on the country dashboard.
What are the biggest threats to wildlife in Thailand?
The leading threats to threatened species in Thailand are logging & wood harvesting, annual & perennial non-timber crops, fishing & harvesting aquatic resources, and housing & urban areas. Each threat is mapped to the species it affects in the country's threat breakdown.
How many threatened species are found only in Thailand?
Thailand has 220 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 Thailand's threatened species have declining populations?
643 of Thailand'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 Thailand compare to other countries for threatened species?
Thailand ranks #40 of 253 countries by number of threatened species, and accounts for roughly 1.84% 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 Thailand 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 Thailand profile — species, national red list, and protected areas — can be downloaded as a CSV spreadsheet or a branded PDF report.
