Helicopters begin to be used for various forestry operations.
Helicopters were used for baiting in reforestation efforts. Baiting involved spreading wheat seeds soaked with a rodenticide (pesticide designed to kill rodents) in recently planted forests in order to give the tree seeds the opportunity to germinate and grow. This ensures the planted trees establish quickly, which in turn helps prevent soil erosion.
Helicopters were used in various firefighting efforts, including dumping fire-retardant chemicals on fires, transporting people and equipment, and observing the fire from a high vantage point.
