The community peatland rewilding initiative in Finland shows how local action can reverse environmental damage and create carbon-storing wetlands that support wildlife.
A small Finnish village has transformed a barren peat mining site into a thriving wildlife paradise, now home to over 190 bird species. The rewilding initiative in North Karelia demonstrates how it can transform environmental disasters into thriving ecosystems.
Linnunsuo, locally known as the “Marsh of Birds,” was once a lifeless mining operation that polluted nearby rivers. Today, it serves as home to endangered species and attracts up to 100,000 migrating geese each autumn. The transformation took just one year after restoration began.
The wetland’s revival started after a 2010 environmental disaster. Acidic water from the mining site killed fish and seagulls in the Jukajoki River. Local fishers spotted the dead animals floating downstream and raised the alarm. Water tests revealed pH levels of 2.77, making the water as acidic as lemon juice.
Tero Mustonen, a climate scientist and co-founder of Snowchange Cooperative, led the community response. His group bought the 1.1 square kilometer site from the VAPO mining company (now Neova). They immediately began flooding the acidic soil to prevent further environmental damage.
The peatland rewilding approach focuses on restoring water to damaged landscapes. Peat mining exposes iron sulfate soils to oxygen for the first time in thousands of years. When rain or snow falls on these soils, it creates extremely acidic runoff that kills aquatic life.
Snowchange built interconnected pools across the former mining site. The pools submerged the acidic soil and stopped harmful emissions. Within months, the area transformed from a carbon source into a carbon sink. Peatlands can store three times more carbon than forests when properly managed.
The speed of wildlife recovery surprised even the restoration team. Endangered Northern Pintails and Greater Spotted Eagles now nest at Linnunsuo. Wolverines hunt among the wetland pools, while bears and moose venture from nearby forests. Sphagnum moss has naturally re-established itself, creating the foundation for long-term carbon storage.
The community effort represents a new model for conservation. Instead of keeping people away from nature, the peatland rewilding integrates local knowledge with scientific methods. Local hunters help manage the site by controlling invasive species, such as mink and raccoon dogs, that threaten native birds.
Only 12 people from the village of 300 initially worked on the restoration. Their success attracted international attention and funding. Snowchange has since expanded to manage 550 square kilometers of damaged peatlands and forests across Finland.
The approach challenges traditional conservation methods. “We are restoring the ecosystem but also giving the land back to the people, ensuring they are stewards of this place,” Mustonen explains. Local fishers detected the original pollution event, not government monitors or company officials.
Finland faces unique challenges with peatland conservation. One-third of the country consists of peatlands formed during the Ice Age. However, nearly half of Finland’s peatlands have been drained for timber production or mined for fuel. According to the Intergovernmental Panel on Climate Change (IPCC), damaged peatlands account for nearly 6% of all human-caused carbon emissions globally.
Climate change poses new threats to restored wetlands. Extreme weather events, such as heavy rains and droughts, can damage fragile ecosystems. Dry peat catches fire easily and can smoulder for weeks. Snowchange monitors weather patterns closely and adapts management strategies accordingly.
The restoration team faces ongoing challenges from surrounding land use. Road construction and forestry operations near Linnunsuo require constant vigilance. Snowchange conducts regular water quality monitoring and removes invasive plants, such as Japanese knotweed, to protect the wetland’s health.
The peatland rewilding offers hope for similar projects worldwide. The success at Linnunsuo proves that communities can reverse environmental damage through collective action. The project has become a model for Indigenous and Community Conserved Areas globally.
Mustonen won the 2023 Goldman Environmental Prize for his work at Linnunsuo. The award recognizes grassroots environmental leaders who create lasting change in their communities. His approach combines traditional Finnish forest culture with modern scientific understanding.
The wetland’s transformation offers multiple benefits beyond providing a wildlife habitat. The restored peat bog prevents acidic runoff from reaching local rivers. Fish populations have recovered in waterways that were once lifeless. The carbon storage capacity helps Finland meet its climate action commitments.
Residents have taken on the role of environmental stewards. The project strengthens community connections to traditional land use practices. Hunting and fishing continue under sustainable management that protects vulnerable species while maintaining cultural traditions. Local people gain control over their landscape while creating valuable ecosystem services.
The Linnunsuo peatland rewilding story represents a practical solution to climate change that communities worldwide can adapt. The approach works because it addresses both environmental and social needs. Success depended primarily on community commitment and traditional ecological knowledge passed down through generations.
Snowchange continues expanding its restoration work across northern Finland. Each project builds on lessons learned at Linnunsuo while adapting to local conditions. The organization collaborates with indigenous communities across the Arctic to share knowledge and techniques.
The success at Linnunsuo offers a powerful symbol of environmental recovery. A small community transformed an ecological disaster into a thriving ecosystem that benefits wildlife, stores carbon, and maintains cultural traditions. Their achievement demonstrates that local action can create global environmental benefits.
