Water trickles slowly across the spongy ground at Isosuo, a raised bog in southern Finland where beavers have returned and rare birds are beginning to nest again. Just a few years ago, this land was dry and cracked, drained for forestry and losing carbon with every passing season. Now, thanks to the work of local conservationists, life is creeping back into the misty landscape.
Peatlands like Isosuo are quiet climate heroes. Though they cover only 3% of Earth’s surface, they store more than 30% of the world’s soil carbon — more than all the planet’s forests combined. When healthy, they soak up water, prevent floods, and shelter unique wildlife. But when drained, they rot and release carbon dioxide, turning from carbon vaults into pollution sources. In Finland, where peatlands cover one-third of the country, over half have been drained in the past century. The Isosuo project is part of a growing effort to reverse that damage.
Led by the Finnish NGO PLUPS (Foundation for Better Nature), the restoration began in earnest in 2024. Teams blocked old drainage ditches with leaky dams, allowing water to rise and rewet the dried-out peat. This simple act helps restart natural processes: mosses return, insects follow, and birds like the wood sandpiper and black-throated diver find new homes. So far, 180 to 300 hectares — about 300 football fields — have been rewilded, with plans to expand further.
The project doesn’t just rely on science. PLUPS blends ecology with art and community outreach, inviting locals to walk the bog, share stories, and help monitor wildlife using camera traps. This mix of knowledge and connection has made Isosuo a model for others. In 2024, it joined the European Rewilding Network, a coalition of conservation projects across the continent. Now, lessons from Finland’s bogs can inspire restoration in Sweden, Germany, and beyond — while Isosuo learns from others too.
"Joining the European Rewilding Network connects Isosuo with a vibrant community that is demonstrating how rewilding can make a real difference for climate, wildlife and people," says Antoine Scherer, a rewilding expert at PLUPS.
Today, Isosuo is more than a recovering bog — it’s a sign of what’s possible. As water rises and green returns, the land begins to breathe again, pulling carbon from the air and offering refuge to species under pressure. With climate change bringing fiercer storms and longer droughts, places like Isosuo could become nature’s shock absorbers. And as Europe looks to heal its wounded landscapes, this quiet bog in southern Finland may just help light the way.
