Tree stability in winds and the effect of how pruning can change wind loads on trees is still not well understood. While trees provide many benefits to urban and suburban landscapes, they can cause catastrophic damage when they fail. In the United States, a growing climate of liability and concern for public safety has increased the need to identify conditions that may lead to tree failure, and to substantiate decisions to retain or remove trees. Recent studies of shade trees have investigated the effects of defects such as decay and included bark, but there is still a pressing need to develop knowledge about thresholds for such defects. Furthermore, a better understanding of wind loading of shade trees is critical when assessing structural stability and the potential of failure.
This project used dynamic structural methods to study large trees under high wind conditions, providing real data of wind loads on trees. Different tree species were monitored at various sites around the world.
