    Rhinos: Rangers, science and new homes to bring rhinos back.

    The problem

    What we're up against.

    • Hundreds lost every year.

      Poachers killed 516 rhinos in Africa in 2024, 81.4% of them in South Africa. Populations hold steady only if poaching stays at or below 3.5% a year.

    • Fewer poached, but not everywhere.

      South Africa lost 352 rhinos in 2025, fewer than the year before, but Kruger National Park lost 175.

    • Asia's last rhinos.

      Poachers killed 33% of all Javan rhinos in a few years, and only 34 to 47 Sumatran rhinos are left.

    • Organized crime.

      The horn trade runs on corruption and well-armed networks, and slow courts make it harder to stop.

    What works

    Proven, and ready to grow.

    • Dehorning.

      Across Greater Kruger's reserves, removing horns cut poaching by about 78% for just 1.2% of the budget, at about $570 a rhino each time.

    • Strong protection can reach zero.

      Nepal has recorded no rhino poaching in ten separate years, and Rwanda's Akagera park has lost none in 15 years.

    • Stopping poachers before they strike.

      In Namibia, 45% of poacher arrests over seven years came before a planned attack.

    • Science for the rarest.

      The BioRescue team has made 38 northern white rhino embryos, the species' only path to a future.

    What a family could fund

    Where the money goes furthest.

    • A rhino protected for a year.

      Greater Kruger spent about $3,120 a year on protection for each rhino living there.

    • New homes, safely.

      African Parks is moving a herd once kept in captivity into protected parks, with a goal of 2,000 rhinos.

    • Where money is scarcest.

      Sustainable funding is urgently needed in Asia, especially Indonesia, for the protection its rhinos depend on.

    Honest limits

    What money can't promise.

    • Poachers move next door.

      When Kruger dehorned, poaching shifted to other parks, and poachers still take horn stumps and regrowth, so dehorning has to be repeated.

    • Dehorning changes rhinos.

      Dehorned black rhinos were 37% less likely to meet other rhinos.

    • Fewer poached, fewer left.

      One analysis finds poaching pressure on each rhino has stayed high, because there are fewer rhinos to find.

    • Rangers pay with their lives.

      174 rangers protecting wildlife around the world died in a single year, and the true number is higher.

    • Changing demand is unproven.

      A review of campaigns to cut demand for wildlife products couldn't tell whether they changed behavior.

    Hard questions

    Asked and answered.

    1. You might ask

      If rangers showed no measurable effect, why pay for them?

      Ryan

      That study couldn't tell, which isn't the same as no effect, and dehorned rhinos still need guarding.

    2. You might ask

      Is saving two northern white rhinos worth it?

      Ryan

      It's a long shot: none of the embryo transfers so far has become a lasting pregnancy. But dehorning shows how much a little money can do, and the science learned could help other species.

    3. You might ask

      Would a legal horn trade pay for protection?

      Ryan

      It's contested. One review concluded a legal trade would likely harm wild rhinos, though some rhino owners argue otherwise.

    Rhinos

    The slider prices this cause with these numbers:

    • About $3,120 a year paid for one rhino's share of protection in South Africa's Greater Kruger area.
    • The whole need is every wild rhino: about 26,699, counting 22,540 in Africa and 4,159 in Asia.
    • A share of the bill in one costly, high-threat place, not a rhino saved: most protection there showed no clear effect, while dehorning did.
