Green Trees

Trees are vital. As the biggest plants on the planet, they give us oxygen, store carbon,

stabilizethe soil and give life to the world’s wildlife. They also provide us with the materials

for tools and shelter.Not only are trees essential for life, but as the longest living species

on earth, they give us a link between the past, present, and future. It’s critical that woodlands,

rainforests, and trees in urban settings, such as parks, are preserved and sustainably

managed across the world.Trees benefit health. The canopies of trees act as a physical

filter, trapping dust and absorbing pollutants from the air. Each individual tree removes up

to 1.7 kilos every year. 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, has antiseptic properties.

Research shows that within minutes of being surrounded by trees and green space,

your blood pressure drops, your heart rate slows and your stress levels come down.

Trees benefit 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’s 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 liters of stormwater.

Trees boost wildlife

Trees host complex microhabitats. When young, they offer habitation and food to

amazing communities of birds, insects, lichens, and fungi. When ancient, their trunks

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 it has been designated a National Nature

Reserve and Site of Special Scientific Interest.

Trees strengthen 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.

Trees grow the economy

People are attracted to live, work and invest in green surroundings. Research shows

that average house prices are 5-18% higher when properties are close to mature trees.

Companies benefit from a healthier, happier workforce if there are parks and trees nearby.

Trees protect the future

Soon, for the first time in history, the number of people with homes in cities will outstrip

those living in the countryside. Parks and trees will become an even more vital component

of urban life. We must respect them and protect them for the future.
