Hazard Reduction Pruning Is recommended when the primary objective is to reduce the danger to a specific target caused by visibly defined hazards in a tree. For example, HRP may be the primary objective if a tree has many dead limbs over a school yard.
Many times safety is of the upmost importance when trees are located around valuable assets or populated areas. A good example would be a large eucalyptus tree located in the center of a school yard. In this case the children would be the “target” and the threat would be the tree, mitigations would need to be considered to reduce the hazard of this tree.
