Tree Pulling Test

The tree-pulling test is a practical method employed to assess the stability and structural integrity of trees, especially in situations where their stability is in question. This technique involves attaching a calibrated force or load to a tree using specialised equipment, such as a winch or hydraulic system, and then applying controlled tension to the tree in a specific direction. Arborists or researchers monitor the response of the tree (deformation of the stem and inclination of the root plate) to the applied force, which can reveal valuable information about its stability. This test can lead to the identification of potential failures, such as stem breakage or uprooting. This test provides essential data for evaluating trees’ safety in urban or natural settings and aids in making informed decisions regarding tree management, including pruning or removal when necessary.
