The helicopter operator reported that, during takeoff, the pilot allowed the helicopter to drift aft during a pedal turn, which resulted in the main rotor blades impacting tree branches that outlined the confined area of the landing zone. The pilot completed the remainder of the flight without incident. The helicopter sustained substantial damage to the antitorque gear box. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
