Tree anchoring in the soil by fixation of the root system is the most basic aspect of tree stabilization and resistance to uprooting. Understanding of this phenomenon is important especially in parks, in the linear alleys, and for solitary individuals in an urban environment as well as in the forest vegetation. There is a whole range of methods for assessment, which are used. Generally it is possible to divide them into destructive (mechanical) or non-destructive (physical and ecophysiological) methods. The present paper briefly discusses conventional and traditional methods of excavating the roots that are used particularly in rating trees of rather small dimensions, or assessing cultures, while evaluating, within a broader context, more recent methods making use of supersonic airflow (mechanical, destructive methods) and also assessment through the use of geophysical radars (physical method). These methods, stemming from various physical principles, can be logically used in combination with ecophysiological, non-destructive methods.
