People tend to take trees for granted. And some still assume that planting trees in cities does not need more than digging a hole and planting the tree. Nothing could be further from the true for the urban landscape. Although we all learn there should be a balance between tree size and root system. But probably we forget, trees will grow. If you want healthy, mature, functional trees specify the right soil volume according the future trees canopy size .
It’s obvious that city green (parcs, trees, turf, plants) beautify our urban environment, the so called green infrastructure. Besides being beautiful, only urban trees provide so many other benefits that trees are regarded as the basis of city’s “green infrastructure.”
Most important benifit is being the solution to slow down climate change. Research all around the world shows trees are the most efficient and effective way in fighting climat change.
Climate change is affecting us now. As different parts of the country become drier, wetter or hotter, green infrastructure can help improve community resiliency today and into the future.
Planting more trees can help communities prepare for and manage the effects of climate change in their city:
It is an accepted fact that mature trees can contribute significantly to healthier soil, air, and water in cities. But cities are not typically hospitable places for plant growth, and trees seldom live long enough to reach maturity and provide meaningful ecological services. In the forest you can dig a hole plant a tree and it will grow. No one will complain about roots growing just below the surface, or about leaves falling on the ground. In the city we are dealing with a totally different expectation pattern. We want the roots to grow deeper so they won't damage the paving. We have to take into account the fact, the urban soils are used in a multifunctional way; urban forestry, civil works and water management. Respectively combining green gray and blue.
Because of these harsh conditions in the city, we have to try to reach the most ideal situation for the tree. Time has past for mono-functional use of space .
