History of National Tree Week
The beginnings of National Tree Week date back to 1973 when British parliamentarians Sydney Chapman and Peter Walker launched a campaign to raise awareness about the threat of Dutch elm disease, which was killing a substantial number of trees across the United Kingdom. Dutch elm disease hinders trees from efficiently absorbing water, so this was considered a major concern.
The celebrations were initially called Plant a Tree in ’73 and called upon communities across the country to plant as many trees as they could throughout the year. Festivities usually begin at the tail end of November as it is the beginning of winter, and trees are recommended to be planted during this period before the cold sets in. The U.K.’s tree planting season lasts from November until March — and National Tree Week signals its beginning.
Trees have a critical role in the natural ecosystem that cannot be overstated. They help collect carbon dioxide from the air and release it as oxygen, making them important pollutant controllers. More trees provide better air quality and more pockets of shade to shield us from the elements, all of which are good for human existence. The presence of trees also aids the surrounding species by providing them with shelter and food, while the soil obtains the nutrients it requires to develop stronger and more fruitful.
As part of National Tree Week, various British city and borough councils hold tree planting and awareness events to spread the message and green up their surroundings. In urban environments, planting more trees helps the public create closer connections to nature. It also ensures that our living environment remains healthy and beautiful.

Why National Tree Week is Important
It is a week that celebrates trees as a giver of life
Trees play an important role in the survival of life on Earth. Their contributions may not be recognized or appreciated as much as they should be since they do it silently. National Tree Week highlights the function and importance of trees in maintaining the balance of nature, as well as why we should care for them.
It reminds us of the importance of trees in keeping nature in balance
It's never a happy sight to see a tree being unnecessarily cut down or damaged beyond repair. The loss of one tree can affect the environment in which it stands. The surrounding soil might not receive the adequate amount of nutrients it needs, or the quality of air could worsen around you. That is why National Tree Week helps remind us that they play a vital role in keeping the environment healthy and pleasant.
Trees help us connect with nature
The lack of trees can also affect the natural state of your area. Have you ever felt so disconnected from nature whenever you see an area that was once teeming with trees but is no longer so? Such a sight can break your heart, and more importantly, drives wildlife and nature further from us. Thus, National Tree Week also serves to remind us that trees help us become more connected to nature, which is important to realize in an increasingly industrialized world.
