Frequently asked questions

How many threatened species are in Croatia?
Croatia has 780 threatened species recorded on SpeciesRadar — 154 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 Croatia have?
Of the 780 threatened species in Croatia, 154 are Critically Endangered, 221 are Endangered, and 405 are Vulnerable. Together these three IUCN Red List categories make up the "threatened" total.
What is the most endangered species in Croatia?
Among the 154 Critically Endangered species in Croatia, Dalmatinella fluviatilis 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 Croatia?
SpeciesRadar does not yet catalogue protected areas for Croatia. 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 Croatia?
The most affected groups in Croatia, by number of threatened species, are insects (407), arachnids (75), and molluscs (67). The full taxonomic breakdown is shown on the country dashboard.
What are the biggest threats to wildlife in Croatia?
The leading threats to threatened species in Croatia are urban development and infrastructure expansion, type unknown/unrecorded (pollution), housing & urban areas, and logging & wood harvesting. Each threat is mapped to the species it affects in the country's threat breakdown.
How many threatened species are found only in Croatia?
Croatia has 40 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 Croatia's threatened species have declining populations?
98 of Croatia'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 Croatia compare to other countries for threatened species?
Croatia ranks #51 of 250 countries by number of threatened species, and accounts for roughly 1.40% 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 Croatia 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 Croatia profile — species, national red list, and protected areas — can be downloaded as a CSV spreadsheet or a branded PDF report.
