Abstract

The population of trees that has been immersed in the cities are victims of abuse of the people, attacks and other conditions thatoften cause injury and damage to trees that are undetectable by inspection of the outer tree bole. The use of the Resistograph, as a useful toolfor detecting internal anomalies, it is a simple andaccurate technique that is based on fade into the tree a fine steel drill, which as it enters and passes through the wood it encounters  a variable amounts of resistance, once interpreted, is able to reflect results as internal  cavities and decays, variations in annual growth rings and how the tree has beendeveloped in response to environmental conditions encountered.
