The City of London tree inventory was undertaken in the summer of 2002 and is regularly updated to reflect spring and fall tree planting programs as well as the removal of dead or hazardous trees. The data assists the City's Forestry Group in managing its year-round maintenance program as well as planning what tree species to plant and where. Trunks are measured at the standard diameter height of 1.4 meters (4.5 feet) above the ground. Leaning trees, multi-stemmed trees and other abnormal conditions are measured using professional appraisal techniques. For London residents a practical use of the trunk measurement is being able to assess tree root impacts for any planned construction. Every effort should be made to stay 30 cm away from the trunk for each 3 cm of trunk diameter. |
