Why Are Trees So Important?

Trees are the biggest plants on the planet. They provide a sense of the continuity of life and we appreciate them for the link they provide between past, present and future.

But trees are important for many practical reasons – as well as spiritual ones.

Improving Health

The canopies of trees act as a physical filter, trapping dust and absorbing pollutants from the air - removing up to 1.7 kilos per tree annually. They also provide shade from solar radiation and reduce noise.

Over 20 species of British trees and shrubs are known to have medicinal properties. The oil from birch bark, for example, is antiseptic and can be used to treat eczema.

Benefitting the Environment

Trees absorb carbon dioxide as they grow and the carbon that they store in their wood helps slow the rate of global warming.

They reduce wind speeds and cool the air as they lose moisture and reflect heat upwards from their leaves. It is estimated that trees can reduce the temperature in a city by up to 7°c.

Trees also help prevent flooding and soil erosion, absorbing thousands of litres of stormwater.

Boosting Wildlife

Trees host complex microenvironments. When young, they offer habitation and food to amazing communities of birds, insects, lichen and fungi. When ancient, they also provide the hollow cover needed by species such as bats, woodboring beetles, tawny owls and woodpeckers.

One mature oak can be home to as many as 500 different species. Richmond Park is full of such trees – which is one of the reasons why it has been designated a National Nature Reserve and Site of Special Scientific Interest.

Strengthening Communities

Trees strengthen the distinctive character of a place and encourage local pride. Urban woodland can be used as an educational resource and to bring groups together for activities like walking and bird-watching. Trees are also invaluable for children to play in and discover their sense of adventure.

Growing the Economy

People are attracted to live, work and invest in green surroundings. Research shows that average house prices are between 5%-18% higher where properties are close to mature trees and companies benefit from a healthier, happier workforce if there are parks and trees nearby.

Protecting the Future

Soon, for the first time in history, the number of people with homes in cities will outstrip those living in the countryside - so parks and trees will become an even more vital component of urban life. We must respect them and protect them for the future.
