Frequently asked questions

How many threatened species are in Brunei?
Brunei has 348 threatened species recorded on SpeciesRadar — 24 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 Brunei have?
Of the 348 threatened species in Brunei, 24 are Critically Endangered, 101 are Endangered, and 223 are Vulnerable. Together these three IUCN Red List categories make up the "threatened" total.
What is the most endangered species in Brunei?
Among the 24 Critically Endangered species in Brunei, Shorea teysmanniana 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 Brunei?
SpeciesRadar does not yet catalogue protected areas for Brunei. 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 Brunei?
The most affected groups in Brunei, by number of threatened species, are plants (233), birds (36), and mammals (31). The full taxonomic breakdown is shown on the country dashboard.
What are the biggest threats to wildlife in Brunei?
The leading threats to threatened species in Brunei are logging & wood harvesting, annual & perennial non-timber crops, housing & urban areas, 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 Brunei?
Brunei has 23 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 Brunei's threatened species have declining populations?
267 of Brunei'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 Brunei compare to other countries for threatened species?
Brunei ranks #92 of 250 countries by number of threatened species, and accounts for roughly 0.62% 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 Brunei 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 Brunei profile — species, national red list, and protected areas — can be downloaded as a CSV spreadsheet or a branded PDF report.
