Groundbreaking news from Uganda: For the first time ever, scientists have confirmed that an estimated 426 chimpanzees are living within Bwindi Impenetrable National Park — which makes this the only spot on Earth where endangered chimpanzees and mountain gorillas live in the same space.

This important discovery came from the Jane Goodall Institute Uganda and the Uganda Wildlife Authority, who completed a landmark scientific census to better understand chimpanzee distribution in Bwindi. This included providing the first comprehensive, evidence-based assessment of the species’ population, density, and spatial distribution.

And why does this even matter? Because you cannot protect what you don’t know exists. This discovery has confirmed that chimpanzees are an integral part of Bwindi’s great ape population — and now authorities are equipped with the scientific foundation needed to strategically protect them.

“This census was undertaken to address critical knowledge gaps regarding chimpanzees in Bwindi Impenetrable National Park,” explains James Byamukama, Executive Director of the Jane Goodall Institute Uganda.

“The establishment of a scientifically robust baseline on population size, density, and distribution will guide conservation planning, protected area management, and regional biodiversity strategies, while also supporting Uganda’s alignment with international conservation and climate commitments.”

As Dr. Jane said: “Only if we understand, can we care.” Equipped with this new evidence, we’re able to better care for our closest animal relatives — and protect our shared planet.
