The government says spending £4.2 million on planting trees in towns and cities will improve the quality of people’s lives. But do trees really make people happy?

Some British and US surveys suggest a thick green lawn, or well-landscaped yard can increase the government property prices by as much as 15%. But the government’s Big Tree Plant campaign, which aims to plant one million trees in English urban areas over the next four years, says trees are not only good for our bank balance, but they do wonders for our happiness. And it says getting people to plant makes communities even happier. So do people really care about trees and do they improve lives? Margaret Lipscombe, director of urban programs at the Tree Council, says, “Not only are trees beautiful but they are practical. Trees also encourage healthier lifestyles and studies have shown people are calmer when trees are in their community,” A US study suggests that patients who have a view of nature through hospital windows recover better after operations.

Ms. Lipscombe says that the trees have also been known to slow down the traffic because drivers will go more slowly when there is something in their sights. She admits some people have negative feelings about trees because they worry about slipping on berries, bird droppings on cars or blocked light.

Ms. Lipscombe also says when she first moved into the area, there were no trees on her street. “I t was an area where there were lots of factories with high walls. It looked like an abandoned place that you didn’t want, especially as a woman on your own. Now everything is different. With lots of trees around, the street looks more attractive. People are not as frightened and no longer run down the road to get home. The trees also bring people out onto the street and make a stronger community feel.”
