Last year, a survey was conducted that revealed the trees in London are worth staggering but worthy £6.1 billion to the nation’s capital.

Altogether there are as many as eight million trees, which also contribute £130 million in wider benefits, annually.

But why?

The answer really is quite plain and simple; they keep London clean.

Up to 300 volunteers were involved in analysing and counting trees in order to find out the services they provide such as the carbon they store and the pollution they remove, as part of the iTree urban forest survey.

The study discovered that trees store 2,367,000 tonnes per year of carbon. This is remarkably impressive, and when you consider it’s a service worth £146.9 million it is even more impressive to think what nature does to help us on the daily. Additionally, the trees in London were said to remove 2,241 tonnes per year of pollution, worth £126.1 million. Isn’t the humble tree just magnificent?

You don’t have to be a ‘tree-hugger’ or be a treehouse camping fanatic to appreciate one of nature’s greatest creations, but we often take for granted the significance they have on our lives. Further to the iTree survey it was highlighted that London’s canopy also relieves £2.8 million worth of storm water each year, and to replace the services that our urban foliage offers would have a price tag of £6.1 billion.

 

Now we know how effective and amazing London’s tree are, how about we take a look at some more interesting facts about the humble tree?

 

1. A mature tree removes as much as 70 times more pollution than a tree that has been newly planted.

2. A single tree produces approximately 119kg (18.6 stone) of oxygen annually. That means two mature trees can be the source of enough oxygen per year to support a family of four!

3. One tree can absorb as much carbon in a year as a car produces while driving 26,000 miles.

4. Over the course its life, a single tree can absorb one ton of carbon dioxide.

5. The average tree in an urban/city area has a life expectancy of just 8 years.

6. Hospital patients need less painkillers, heal faster, and need shorter stays if their room windows face trees.

7. A fully-grown Oak in the UK grows – and sheds – a whopping 250,000 leaves per year and produces roughly 50,000 acorns, providing it’s a good year.

8. One person causes about 10 tonnes of carbon dioxide to be emitted a year. One tree removes about 1 tonne of CO2 per year.
