چکیده
Why do we plant trees into our landscapes? The answer is easy. We plant them because they filter dust and absorb pollution, provide shade, shelter, deflect and soften noise, reduce wind velocity and glare. The aesthetic of tree lined streets and green spaces have been shown to have positive psychological and health benefits to human society including lower rates of mental illness, violence and crime. Trees also have a symbolic value, they can humanise an urban area, allowing us to acknowledge our affinity for the natural world and provide a focus for community participation in landscaping the urban environment. Business and industry executives have found that attractive landscapes result in above average labour productivity, lower absenteeism and easier recruitment of workers with hard to find skills. For these reasons hundreds of thousands of trees are planted into our urban landscapes on an annual basis. Consequently tree planting guidelines and management strategies exist to ensure optimal survival rates of newly planted trees and non-decline of established mature trees. Concepts such as fertilisation, irrigation, mulching, pest and disease control are well researched and their importance understood.
