In 2001, a shock assessment revealed that two-thirds of all trees in Stockholm's city center were dead or dying.
The local authorities knew that a change was urgently needed to revive these essential urban ecosystems.

The local authorities knew that a change was urgently needed to revive these essential urban ecosystems.
Björn Embrén emerged as Stockholm's first "tree officer," pioneering methods to cultivate these trees in an increasingly paved urban landscape.
His commitment stemmed from a former life as a professional gardener.
The crux of the issue lay in 19th-century planting practices that couldn't adapt to the modernized environment.
With more concrete and utility pipes, tree roots were suffocating.
Embrén likened it to putting a plastic bag over their heads.
Inspired by railroad embankments, Embrén created the "Stockholm tree pit" model.
This innovative design allows trees to flourish amidst concrete by using breathable and permeable materials that provide essential air and water.
With benefits such as reduced watering needs and compatibility with heavy traffic, this approach has been a game-changer.
Notably, trees planted using this method thrived better than even older trees.
As this method spreads across cities in Europe and beyond, it's a reminder of the importance of investing in sustainable urban forestry to combat climate change and support biodiversity.
