Conservation Outlook

Outlook: Deteriorating

Tanzania's biodiversity significance stems from its position within the Eastern Arc Mountains and Coastal Forests biodiversity hotspot, alongside the expansive Serengeti-Mara ecosystem and diverse coastal marine environments along the Indian Ocean. The country encompasses critical habitats from the montane forests of the Udzungwa and Uluguru Mountains to the coral reefs of Mafia Island and mangrove systems of the Rufiji Delta. According to IUCN Red List 2025 data, all 29 assessed species are classified as threatened, with insects representing 7 species and plants 29 species, indicating severe conservation challenges for endemic flora and fauna.

The most pressing threats include rapid deforestation in the Eastern Arc Mountains driven by agricultural expansion and charcoal production, particularly affecting endemic plant communities. Coastal development and tourism infrastructure threaten marine ecosystems, while climate change impacts montane forest species with limited altitudinal migration options. Mining activities in mineral-rich areas pose additional risks to localized endemic species.

Tanzania has established extensive protected area networks covering approximately 40% of its territory, including world-renowned parks like Serengeti and Ngorongoro. Community-based conservation initiatives, particularly around wildlife management areas, show promise. However, enforcement challenges and increasing human-wildlife conflict suggest the conservation trajectory remains precarious despite legislative frameworks.

Frequently asked questions

How many threatened species are in Tanzania?
Tanzania has 1,513 threatened species recorded on SpeciesRadar — 252 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 Tanzania have?
Of the 1,513 threatened species in Tanzania, 252 are Critically Endangered, 655 are Endangered, and 606 are Vulnerable. Together these three IUCN Red List categories make up the "threatened" total.
What is the most endangered species in Tanzania?
Among the 252 Critically Endangered species in Tanzania, Cuviera migeodii 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 Tanzania?
Tanzania has 55 protected areas catalogued on SpeciesRadar, sourced from the WDPA and national designations. Notable sites include Lake Manyara Biosphere Reserve, Serengeti-Ngorongoro Biosphere Reserve, Manyara Ranch Conservancy, and Ngorongoro Conservation Area, among 51 others. The full list is sortable and downloadable on the Protected Areas tab.
Which animal and plant groups are most threatened in Tanzania?
The most affected groups in Tanzania, by number of threatened species, are plants (1,003), fishes (190), and insects (79). The full taxonomic breakdown is shown on the country dashboard.
What are the biggest threats to wildlife in Tanzania?
The leading threats to threatened species in Tanzania are annual & perennial non-timber crops, logging & wood harvesting, 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 Tanzania?
Tanzania has 781 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 Tanzania's threatened species have declining populations?
629 of Tanzania'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 Tanzania compare to other countries for threatened species?
Tanzania ranks #20 of 253 countries by number of threatened species, and accounts for roughly 2.71% 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 Tanzania 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 Tanzania profile — species, national red list, and protected areas — can be downloaded as a CSV spreadsheet or a branded PDF report.
