What is a tree worth? Old trees hold so much history – they’ve witnessed so many seasons, survived changes in the world and adapted to shifting urban landscapes.

They’re synonymous with humankind.

In certain cultures, old trees contain symbolic or religious meaning that can be traced back hundreds of generations. Since the dawn of time, they’ve been providing ecological benefits that protect people and animals alike.

Despite all of this, it’s unfortunate that these wonderous old trees aren’t often prioritised when designing conservation policies and management guidelines for towns and cities in today’s world.

So, to understand how valuable old trees are, here is a fascinating look into a 250-year-old Oak near Toronto, Canada.

What can we learn from this 250-year-old Oaktree?

At this age, it has a lot of wise stories to share.

According to a study from The University of Hamburg, trees store more carbon as they get older. The research also reported that 70% of all the carbon stored in trees is accumulated in the last half of their lives.

It just proves that mature trees are more capable of making cities greener, healthier and more sustainable. If we allow them to flourish over time, our urban communities will be able to gain more ecological, social and economic benefits that even future generations will be able to enjoy.

How do we give trees found in our cities the best opportunity to thrive?

Using products like soil vault systems, tree pit irrigation, tree guards and other root management solutions can go a long way in making sure these city trees will mature healthily within an urban landscape.
