Frequently asked questions

How many threatened species are in Bulgaria?
Bulgaria has 803 threatened species recorded on SpeciesRadar — 149 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 Bulgaria have?
Of the 803 threatened species in Bulgaria, 149 are Critically Endangered, 216 are Endangered, and 438 are Vulnerable. Together these three IUCN Red List categories make up the "threatened" total.
What is the most endangered species in Bulgaria?
Among the 149 Critically Endangered species in Bulgaria, Amara quenseli 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 Bulgaria?
SpeciesRadar does not yet catalogue protected areas for Bulgaria. 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 Bulgaria?
The most affected groups in Bulgaria, by number of threatened species, are insects (517), arachnids (79), and plants (63). The full taxonomic breakdown is shown on the country dashboard.
What are the biggest threats to wildlife in Bulgaria?
The leading threats to threatened species in Bulgaria are habitat fragmentation, urban development and infrastructure expansion, agricultural intensification, and agricultural intensification and pesticide use. Each threat is mapped to the species it affects in the country's threat breakdown.
How many threatened species are found only in Bulgaria?
Bulgaria has 51 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 Bulgaria's threatened species have declining populations?
72 of Bulgaria'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 Bulgaria compare to other countries for threatened species?
Bulgaria ranks #47 of 248 countries by number of threatened species, and accounts for roughly 1.44% 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 Bulgaria 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 Bulgaria profile — species, national red list, and protected areas — can be downloaded as a CSV spreadsheet or a branded PDF report.
