Executive Summary
A Swiss field study finds beaver-made wetlands store far more carbon than nearby areas and may help offset a small share of emissions
- Beaver-shaped wetlands stored carbon at rates up to 10 times higher than similar areas without beavers
- The Swiss site accumulated about 1,194 tonnes of carbon over 13 years
- Average net carbon sink was 98.3 plus or minus 33.4 tonnes of carbon a year
- Most long-term storage came from dissolved inorganic carbon retained below the surface
- Summer low water briefly increased CO2 emissions, but annual storage remained positive
- Methane emissions were minimal, accounting for less than 0.1 percent of the carbon budget
- Scaling to suitable Swiss floodplains suggested offsets of about 1.2 to 1.8 percent of annual emissions
Quick Facts
- What: Measured beaver wetlands as carbon sinks
- Where: Northern Switzerland stream corridor
- Why: To assess climate benefits of beaver engineering
- Who: University of Birmingham and partners
- When: Over 13 years of beaver activity
