We’re aiming to plant and establish 20 million trees by 2030 to benefit people and nature. Find out how the project is progressing across the country and discover how trees capture carbon.

Why we're planting and establishing trees

The most important thing we need to do to tackle climate change is drastically reduce carbon emissions – but alongside that essential work, trees are the best natural solution to lock up existing atmospheric carbon.

We need to act quickly to tackle the worst consequences of the climate crisis and global warming driven by carbon dioxide emissions. As the UK's single biggest private landowner we're in a strong position to help. Planting and establishing more trees will capture carbon from the atmosphere as they grow.

One tree could remove 1 tonne of carbon dioxide from the air over its lifetime. The carbon is not only stored by the tree and the roots but also held in the surrounding soil. As trees grow they absorb and lock in carbon emissions that would otherwise contribute to global heating.

Planting trees to benefit everyone

Woodlands reconnect us with nature. Of the 250,000 hectares of land the National Trust cares for, 10 per cent is woodland. We have made a commitment to increase this to 17 per cent over the next 10 years, meaning we will be planting 20 million trees over the next decade.

Trees have an amazing ability to provide space to breathe and relax, provide a home for nature to thrive and allow us to lock up carbon.

Our approach to tree establishment ensures we maximise the benefit for people and nature, as well as locking up carbon. We'll establish new hedgerows and woodlands as well as creating innovative agroforestry projects and restoring historic wood pasture and orchards – and increasing tree cover in other settings.

We'll help tenant farmers use trees in ways that are beneficial to them. This could involve generating income from ecosystem services such as flood mitigation and increases in biodiversity, improving shelter and shading for livestock, or by cultivating sustainably grown timber. Each project will be tailored to suit the needs of the landscape, habitat or historic place, and with a focus on the benefit it will provide for people.

Choosing the right trees

All the trees will be grown from seed in the UK by nurseries that have very high standards of biosecurity and provenance control – we typically use nurseries in the Plant Healthy or UK & Ireland Sourced and Grown schemes. Natural colonisation will also play a significant role and many trees will establish naturally as we change the management of the land we care for.

Where we do plant, tree species will be carefully chosen with site detail in mind. New native woodlands may include species such as oak, beech, lime, field maple, hazel and hawthorn to support the area's existing ecosystem, while ornamental varieties may be more appropriate where we’re restoring historic designed landscapes.

We have to take actions that can be delivered within the timescales needed to tackle the climate crisis we're facing. The science tells us that tree planting is one of the best ways to absorb carbon. We know it works and there's no time to lose.

Partnering with England's Community Forests

In 2025, we're partnering with England's Community Forests to create around 519 hectares of wooded habitats. By the end of March, almost 416,000 trees will have been planted to make woodlands, wood pasture, hedgerows and orchards.

A total of 20 planting projects will be completed on land in our care in England to fight climate change, help nature thrive and make woods more accessible and closer to where people live.

Each new area of planting will join existing habitats to form nature-rich landscapes, as well as extending the size of local Community Forest networks in areas including Devon, Gloucestershire, Yorkshire and Merseyside.

Throughout the partnership, we'll work together to create the equivalent of more than 1,070 football pitches of vital, wood-filled habitats.

This series of planting projects has been funded and supported by England’s Community Forests’ Trees for Climate programme, part of the Department for Environment, Food & Rural Affairs’ (Defra) Nature for Climate Fund.
