Tsavo Wildlife Census Annual Results 2025/2026

Tsavo Wildlife Safari Census Annual Results.

The 2025 Tsavo Wildlife Census annual results, which were carried out between June 2024 and August 2025 and released formally in late December 2025, are a complex and highly informative view of the populations of wildlife in Kenya. This triannual census, led under the umbrella of the Wildlife Research and Training Institute (WRTI) with the assistance of the Kenya Wildlife Service (KWS), international conservation partners, aerial survey teams, and ground monitoring units, was bound to determine the trends in the most significant ecosystems in the country, which include the Tsavo Conservation Area.

Although most popular discourse on wildlife counts is usually based on the charismatic species within a country, the 2025 census provides essential information regarding prosperity as well as the declining species. This research will have far-reaching conservation planning consequences, tourism policy, and ecosystem health implications in Kenya in the next decade.

How the Census Was Conducted

The 2025 National Wildlife Census was among the largest and most methodologically advanced counts that had been conducted in Kenya. The work incorporated a combination of various survey techniques: aerial survey, ground surveys (transects), camera traps, expert shadowing and marine surveys. Over 1,500 flight hours were recorded over long transects in national parks and reserves, particularly in the largest conservation area in East Africa, the Tsavo Conservation Area.

Through the support of dozens of aircraft sponsored by organisations such as KWS, Save the Elephants and Tsavo Trust, as well as the current operators and other partners, aerial teams flew thousands of kilometres within a period of seven or eight days directly over the Tsavo ecosystem at the beginning of the census year. This made it possible to count large mammals in detail, especially elephants. Better precision was achieved due to concurrent ground checking and counting procedures.

2025/26 Wildlife Census Key Population Results.

The national initiatives in Kenya are providing positive and negative results. Whereas the growth of some species is promising, some species, particularly the rare and endangered ones, experience severe threats.

Elephants.

The elephant population in Kenya has been increasing, which was one of the most publicised discoveries in the 2025 census. Based on the official statistics:

  • The elephant population in Kenya rose to approximately 41,952, which is a great improvement compared to the population of 36,280 in the year 2021.
  • This is a 4% increase per year, which is a significant indicator that sustained anti-poaching campaigns, habitat conservation programmes, and community conservation membership and participants are producing tangible output.

The Tsavo ecosystem has continued to be particularly significant to the conservation of the elephants. Historically, the most populous place in the country with its huge expanses and relatively preserved habitats, Tsavo has long been the backbone of the total number of jumbos in Kenya. Although precise block-level totals of Tsavo have not yet been incorporated in the final census report, early aerial data have indicated a significant rise in sightings of the elephants and reasonably low amounts of carcasses, which is a good indicator compared to the past few years when poaching pressure was high.

Rhinos

The census also reports current success in conserving rhinos, and the black rhino (which is endangered to extinction) in particular:

  • The total population of the black and white rhinos in Kenya is now about 2,102, as compared to 1,812 in 2021.
  • The growth, which is due to the intensive protection and breeding schemes, is an indicator of another 4 per cent population growth.

This has been aided in large part by intensive conservation efforts in sanctuaries within the Tsavo region, such as the newly expanded Tsavo West Rhino Sanctuary, which now stands as the largest of its kind. These lands enable the rhinos to breed, roam, and have territories, thus reversing decades of decline.

Considering the better figures, the recent management activities have been concerned with ear-notching and monitoring activities involving the rhinos with LoraWAN and VHF tags. The purpose of such steps is to assist wildlife authorities in tracking individual animals in real time and making wise decisions about the movements, threats, and habitat requirements.

Giraffes and Other Grazers

Other classic African megafauna featured in the census included the changes in population other than elephants and rhinos:

  • Giraffes are also performing well, with some 43,002 individuals reported to be nationwide compared with the 35,355 of 2021.

But the other grazers are a more difficult narration:

  • The number of zebras in Grevy also decreased a little to approximately 2,465.
  • The population of rangeland buffalo, too, seems to have decreased (from 41,659 to approximately 27,389), but this may be due to seasonal variation in the survey and not necessarily actual decreases.

These contradictory results imply that food, habitat, water and human pressures are affecting the species in varying ways. In dry and semi-arid regions comprising most parts of Tsavo, these variables are likely to remain influential on the distribution of wildlife.

Endangered and Rare Species

However, possibly, the most alarming results of the 2025 census are connected with the existence of endangered antelopes and carnivores:

  • The hirola, which is one of the rarest antelopes in the world, has dropped to 245.
  • Sable antelope and roan antelope populations are disappearing dangerously.
  • Big carnivores such as lions (2,512), cheetahs (605), and wild dogs (310) are also seen to be in danger, which is evidence of the threat of habitat loss and human-wildlife conflict.

Moreover, the population of waterbirds in prime wetland locations fell by approximately 80 per cent, highlighting the importance of environmental pressure factors, including drought, falling water catchment areas, and habitat destruction.

Conservation

The Tsavo Conservation Area, tens of thousands of square kilometres of protected wild nature, remains important to the wildlife heritage of Kenya. Elephants and rhinos: the state heavily depends on its expansive lands for them to migrate, breed and have water; however, there are more issues:

  • Settlement, agriculture and infrastructure fragmentation habits have broken the migration corridors that previously enabled free movement within the region.
  • The arid savannah of Tsavo is put under increasing pressure by climate change and drought on food and water resources.
  • The issue of human-wildlife conflict is also a burning local issue in areas where animals are found, even outside of the park borders.

Conclusion

The Tsavo Wildlife Census Annual Results 2025/2026 demonstrate conservation successes and significant causes for concern. Significant growth in the number of elephants and rhinos is an indication of what can be accomplished through consistent and science-based action. However, sharp drops in endangered antelopes, waterbirds, and other endangered species demand new urgency in conservation, habitat rehabilitation, and long-term planning, most notably in the Tsavo ecosystem, which has been a cornerstone of the Kenya national heritage.
