Given the choice of a concrete jungle or urban landscapes with a rich tree cover, the public's preference is clear. Making a greener and more attractive environment with the use of tree planting can help to both soften and compliment the built environment. Bringing both colour and softening harsh lines of buildings, trees can also help screen unsightly views and enhance the overall character of an area.
The canopies of trees act as a physical filter, capturing dust and tiny particle matter (PM) on the surface of their twigs and leaves, as well as filtering other toxic particles such as lead. High levels of particulate matter have a detrimental effect on health, particularly worsening chronic diseases such as asthma and bronchitis.
There are numerous studies that show the emotional benefit of a green environment, and how viewing nature can help individuals recover from a stressful experience. A nine-year study of patients at a suburban Pennsylvania hospital following gall-bladder removal, showed that patients with a natural view from their window not only required less pain medication, but also shorter post-operative hospital stays.
Trees and woods in towns provide extremely successful wildlife habitats, supporting a great diversity of popular wildlife and an opportunity for people to enjoy nature on their doorstep. Trees provide nesting sites for birds and support a wide range of insects that are an important food source for birds and other wildlife. Fruit and berry bearing trees are also a direct source of food for many species of bird.
The positive impact of greenery also transfers over to indirectly helping the local economy. Two of the main areas are:
When introducing trees to a project, it's important that any new or existing trees are cared for correctly. With young and semi-mature trees, the addition of tree grilles can not only improve the aesthetic quality, but also protect the roots in high traffic areas, as well as preventing compacted soil by allowing rainwater into the roots.
To aid and protect young trees, tree guards can be added to protect the trees from pedestrians, animals and vehicles. The long lasting tree protection ensures the health of the tree, maintaining the greenery of an area for years to come.
