Termites infestation is a big problem for trees. It is also very difficult to find the trees with termite damage. It is essential to find the trees with initial level of termite damage so that the trees can be treated with suitable available treatments. It is proposed here a new technique using vibration analysis which can detect the termite damage inside the tree trunks by just performing very simple vibration experiment. This method is cheap, efficient and can potentially save large number of trees from dying due to termite infestation. By performing laboratory level experiments, this research proves the feasibility of this simple technique of damage detection in trees.
