Revitalizing Wildlife Surveillance: The Power of eDNA in Africa’s Ecosystems
The innovative application of environmental DNA is transforming how researchers monitor biodiversity across the African continent.

Scientists in Rwanda’s Volcanoes National Park are harnessing eDNA to safeguard rare species such as mountain gorillas and golden monkeys. This groundbreaking approach uses genetic traces from environmental samples to detect wildlife presence without direct observation.
Key insights highlight the technology’s potential: it enables comprehensive assessments by collecting samples from water and soil, identifying species across multiple taxa, and even supporting conservation efforts in hard-to-reach areas.
The African Wildlife Foundation, in collaboration with local authorities, is implementing this method to build detailed biodiversity maps. By doing so, they aim to strengthen conservation strategies amid climate change and expanding human populations.
However, challenges remain. Accurate quantification of species abundance is difficult due to DNA persistence in the environment. Efforts are underway to develop region-specific DNA databases and train local communities, ensuring the technology becomes a sustainable tool for African conservationists.
