Under natural and especially urban stresses many trees become hazards to life and limb. Broken branches and fallen trees can create power failure. Utilities have trained their line clearance personnel to preserve the integrity of trees within the utility right-of-way. But tree workers have to make critical decisions which may annoy or disturb the homeowner or tree advocate. ER -
