About Plant One

Britain was once a wooded isle. We’ve destroyed 70% of our ancient woodland. We’re bringing it back.

Plant One is a Community Interest Company on a mission to restore Britain’s lost woodlands — acre by acre, in Cornish soil. Since 2021 they have planted almost 110 hectares of land with over 75,000 trees. But planting is only the start. Their real work is nurturing those trees into species-rich, biodiverse habitats that will be standing long after we’re gone.

The UK has the lowest tree cover in Europe. Cornwall sits at just 9% canopy cover. In 40 years, 60% of UK wildlife has vanished. Plant One’s work is not abstract. It is local, accessible, and publicly visible — every site open to the communities around it.

Their trees have an 84% survival rate, far above the 56% industry average. That is what it means to establish a woodland, not just plant a field.

Why this matters

Not just planting trees. Restoring a living system.

Biodiversity

Woodlands support 30% of all biodiversity

From humble hedgerows to mighty Celtic rainforest, woodlands provide habitat, food and shelter for species that cannot survive without them — including the pollinators our food system depends on. Every tree planted is a home returned.

Carbon

Established, not just planted — real, lasting capture

Plant One care for each site for at least seven years, replacing trees that don’t survive and protecting natural regeneration. With an 84% survival rate, this carbon capture is real and compounding. Woodland that will be standing long after we’re gone.

Community

Local. Accessible. A place your clients could visit.

Every Plant One site is publicly accessible where possible. Tree planting days, woodland wellbeing events, community workshops. For UK venues and their clients, this is not a distant abstraction — it is somewhere they could walk through, feel connected to, and point to with pride.

No Trees No Seas

The key to healing our seas lies on the land.

Plant One Cornwall · No Trees No Seas campaign film

Campaign goal
500 hectares of fish forests
Across Cornwall over the next five years — species-rich biodiverse woodlands planted in the areas that will have the greatest impact on the flowscapes.

For thousands of years, Britain’s forests swept right to the sea’s edge. A landmark scientific review by the Woodland Trust and Dr Benjamin Phillips proved what we always sensed: forests and seas are one living system — a flowscape.

1
Forests feed the sea
Forest floors brew nutrient-rich ‘forest tea’ of fulvic acid and iron. Rain carries it downstream to the ocean, feeding plankton — the foundation of the entire marine food web. Plankton biomass can be up to 10× higher in estuaries with healthy forested land upstream.
2
The ocean feeds the forest
Salmon return upstream to spawn. Seabirds nest in the trees. Both carry ocean nutrients back to the forest floor. Trees along salmon-rich rivers grow up to three times faster.
3
Forests protect the ocean
Tree roots filter pollution and sediment before it reaches the sea. Forest canopies keep water cool. The forest floor absorbs rainfall slowly — protecting seagrass and kelp, the nurseries for entire marine ecosystems.
4
Cornwall is the right place to start
The wet Atlantic climate creates ideal conditions for temperate rainforest growth. Cornwall is one of the best places in Britain to restore flowscapes — living systems connecting headwater catchments all the way to the deep ocean.
