Healthy soil underpins every thriving ecosystem. Discover how the Green Britain Foundation is restoring soil health to boost biodiversity, strengthen resilience and lock away carbon for generations to come.
Improving soil is one of the most important steps in land restoration. It supports life above and below ground, strengthens ecosystem resilience, and plays a vital role in mitigating climate change.
Healthy soil is not just dirt, it’s a living, breathing ecosystem. When we restore it, we unlock the land’s full potential to nurture biodiversity, regulate water, and store carbon naturally.
Healthy soils are rich in nutrients and hold water more effectively, providing the ideal environment for plants to thrive. This leads to:
Greater vegetation cover.
Increased native biodiversity in restored habitats.
Improved yields on agricultural land where appropriate.
Improved soils support diverse and stable plant and microbial communities, making ecosystems more resistant to drought, pests, disease and invasive species.
Healthy soil acts like a sponge — absorbing rainfall, reducing surface runoff, and preventing erosion. This improves groundwater recharge and lowers flood risk, creating more stable conditions for plants and wildlife.
Earthworms, fungi and beneficial bacteria are essential engineers of healthy soil. Their activity improves soil structure, cycles nutrients and supports the entire food web from the ground up.
Soils are one of the planet’s largest carbon sinks, holding more carbon than the atmosphere and all plant life combined. Restoring soil health directly supports climate action.
As plants grow and decompose, they feed the soil with roots, leaves and organic matter. In healthy soils, this material breaks down and is stored as stable carbon — improving fertility while capturing CO₂ from the atmosphere.
Degraded soils often release carbon through erosion and oxidation. Restoration — including rewilding and reduced disturbance — helps turn these carbon sources into carbon sinks.
Healthy soils can store carbon for decades or even centuries when protected by stable soil aggregates, low disturbance practices and permanent vegetation cover.
Soil and plants work together in a natural carbon feedback loop. Healthier soil supports more vigorous growth; stronger roots capture more carbon; and that carbon, once returned to the soil, feeds the cycle of renewal.
At the Green Britain Foundation, soil health is a core indicator of success across our rewilding and replanting projects. Because soil health is often invisible to the eye, we use scientific monitoring to track real change over time.
We’ve conducted baseline soil surveys to measure physical structure, biodiversity, water retention and soil organic carbon. These data provide a foundation for long-term monitoring and impact reporting.
We expect to see measurable improvements in:
Soil structure and fertility.
Water retention capacity.
Soil organic carbon levels and sequestration potential.
These changes will be most evident in areas previously used for intensive grazing or where woodland canopy thinning allows light to reach the forest floor, encouraging ground cover and soil regeneration.
Healthy soils are where restoration truly begins: unseen, but essential. By caring for the ground beneath our feet, we give nature the stability it needs to recover and thrive.
Green Britain Foundation analysis of nearly 1,000 Freedom of Information spreadsheets reveals Scotland's salmon industry is covering up the true scale of bird deaths in its nets - a finding backed by footage of trapped and dead birds at farms that reported nothing.
