root damage

Street trees are an everyday part of life that are regularly incorporated into typical residential street and shopping area landscaping designs by councils and city planners. Street trees provide many environmental and stormwater management benefits including increased aesthetic values, reduced heat island effects and stormwater runoff reduction. However urban areas can be hostile environments for street trees and a trees health can often suffer due to a lack of desirable conditions. Impervious pavements prevent water and oxygen, vital for tree growth, from infiltrating to the tree roots. This can often result in costly damage to infrastructure as tree roots search out new moisture sources. Permeable pavements are a relatively new technology that allows water and oxygen to infiltrate through the pavement surface and into the soil below. Permeable pavements may offer a viable solution to enhance street tree performance and to reduce pavement damage by tree roots, as well as reducing stormwater flows. A field study is currently underway at the University of the Sunshine Coast to investigate whether permeable pavements with varying sub-base depths can reduce infrastructure damage and increase street tree health. A parallel study is being conducted at the University of South Australia to investigate whether street trees with permeable pavement surrounds can be used to manipulate the growth and distribution of tree roots in urban environments to minimise the effects of reactive soil movements. This paper describes the experimental design and presents the interim results of these studies.
