Birdsong and chimp drumming suggest carbon financing is helping Sierra Leone’s forest
Carbon financing in Sierra Leone’s Gola Rainforest is doing more than locking away carbon — it’s bringing the forest back to life, according to a new study in Conservation Science and Practice. Researchers recorded audio at 133 sites and found the protected park’s dawn chorus was measurably richer than the community forest right next door, with the shift happening sharply at the border. The idea, drawn from the acoustic niche hypothesis, is that more species means more sound frequencies filled, like instruments in an orchestra each holding a lane. It’s one of the first direct signs that REDD+ programs, long sold on climate grounds, may genuinely shelter biodiversity too — a hopeful nudge for how the world funds living forests everywhere.
