ABSTRACT

This study aims to assess the potential of trees for integration in urban development by evaluating the damage caused by trees in relation to various tree characteristics. Tree damage to permeable pavement systems and other urban structures such as impermeable pavements, kerbs, roads, retaining walls, footpaths, walls and buildings were assessed to identify the most suitable trees for the urban environment. One hundred square sites of 100 m × 100 m were randomly selected in Greater Manchester for this representative example case study to demonstrate the assessment methodology. Among tree species in this study, Acer platanoides L. (Norway maple) occurred most frequently (17%); others were Tilia spp. L. (Lime; 16%), Fraxinus excelsior L. (common ash; 12%), Acer pseudoplatanus L. (sycamore; 10%) and Prunus avium L. (wild cherry; 8%). The study concludes that 44% of the damage was to impermeable pavements and 22% to permeable pavements. Other damage to structures included kerbs (19%), retaining walls (5%), footpaths (4%), roads (3%) and walls (3%). Concerning the severity of damage, 66% were moderate, 21% light and 19% severe. Aesculus hippocastanum L. (horse chestnut) caused the greatest damage (59%) expressed in percentage as a ratio of the tree number related to damage over the corresponding tree number that was found close to structures.

Mentions: In order to address objective (1), a total of 100 sites were randomly selected in the Greater Manchester area (North-west England) using the Google Earth map and tools, but restricted within the area of an ellipse covering the main urban areas around Manchester city centre for ease of assessment and to reduce transportation costs (Fig. 1). A square of 100 m × 100 m was drawn around the centre of each selected site to identify an outer boundary for the tree assessment studies. The coordinates, grid references, longitudes, latitudes and post codes of all sites were subsequently determined. The Greater Manchester area is located between 53°28′0″N and 2°14′0″W. The estimated population of Greater Manchester is around 2,680,000.
