Bwindi’s Mountain Gorillas Survive in a Forest Older Than the Last Ice Age

Some mountain gorillas live inside a forest that predates modern humanity.

Bwindi Impenetrable Forest is designated a UNESCO World Heritage Site for its ancient biodiversity.

The Bwindi Impenetrable Forest in Uganda, home to nearly half of the world’s mountain gorillas, is believed to have persisted for over 25,000 years, surviving the last Ice Age when much of Africa’s rainforest contracted. This ancient forest acted as a climatic refuge, allowing species like the mountain gorilla to endure dramatic global cooling events. Bwindi’s dense canopy, steep valleys, and extreme biodiversity create one of the most complex ecosystems in Africa. Mountain gorillas evolved within this long-stable refuge, adapting to its rugged terrain and high-altitude vegetation. Unlike many forests that regrew after glacial retreat, Bwindi maintained continuity, preserving genetic lineages across millennia. The gorillas living there today descend from survivors of planetary-scale climate disruption. Their habitat is effectively older than recorded human civilization.

To grasp the scale, when ice sheets covered vast portions of the Northern Hemisphere, Bwindi’s ecosystem remained intact enough to sustain great apes. That continuity makes it one of Africa’s most biologically resilient landscapes. Mountain gorillas are not just endangered animals; they are relic inhabitants of an ancient ecological stronghold. Destroying such habitat would erase tens of thousands of years of uninterrupted evolutionary history. Few large mammals can claim residency in a forest that endured a global ice age.

Today, agricultural pressure and human settlement surround Bwindi on nearly all sides. What survived planetary cooling may now succumb to chainsaws and farmland expansion. Climate change threatens to alter rainfall patterns that once made this forest a refuge. A sanctuary that protected gorillas from ice age collapse must now shield them from modern development. The timeline of their survival stretches back before cities existed, yet its future hinges on contemporary conservation policy.
