Workshop on Open-grown and Urban Trees 2019



The response of open-grown trees to wind loading is complex and complicated. In contrast to plantation forest-grown trees, which usually have small crowns and only one main axis, the crowns of open-grown trees are often either much larger and/or have of more than one dominating axis. The resulting complexity of the wind-induced crown motion, complicates the in situ assessment of destructive wind loads and thus the assessment of tree stability. Since open-grown trees are an integral part of urban spaces, the assessment of their stability against destructive wind loading is of great importance. The importance becomes particularly evident when the urban tree population gets damaged. At irregular intervals, storms throw and break trees and endanger the urban population and property. It is therefore in society's interest to minimise the hazard to urban trees from storms through appropriate management. The basis for successfully increasing the resistance of the urban tree population against high-impact storms is science-based knowledge about destructive wind-tree-soil-interactions.


Bringing together experts and other interested persons from the fields of wind-tree interactions and stability of individual, open-grown trees against high-impact wind loading. The workshop provides information on the latest scientific findings in these fields. Approaches used to excite tree response to external loads are demonstrated and discussed. One focus of the workshop is on urban trees.
