1. A single mature tree produces enough oxygen back into the atmosphere each year to support 2 human beings.
2. Trees enhance biodiversity. A mature oak can host up to 5,000 different species of invertebrate - forming the basis for a healthy food chain that benefits birds and mammals.
3. One person causes about 10 tons of carbon dioxide to be emitted a year. One tree removes about 1 ton of CO2 per year.
4. Wooded environments are known to calm people, relieve stress and proven to improve mental health and wellbeing.
5. Trees absorb and block sound, reducing noise pollution by as much as 40 percent.
6. By cooling the air and ground around them, the shade from trees helps cool the Earth's temperature
7. A fully-grown Oak in the UK grows - and sheds - 250,000 leaves every year and produces around 50,000 acorns in a good year.
8. An oak spends 300 years growing, 300 years resting and 300 years declining gracefully.
9. Planting a variety of trees and shrubs can help to improve the resilience of our land. This supports our woods and trees, helping them bounce back from threats such as climate change, tree pests and disease.
10. Trees help prevent flooding. Tree canopies slow down the rate at which rainwater reaches the ground while tree roots act effectively suck rainwater deeper underground, which is then released slowly.
