Planting Stock Dropped by Air

In the spring of 1953 a test was made by the Ontario Department of Lands and Forests to determine the feasibility of air delivery of trees packaged in bales. Burlap covered bales were prepared at the Kemptville Nursery, 1.6 inches in diameter to allow dropping through the camera hatch of departmental aircraft. Over 10, 000 baled trees were dropped by 3 methods: by using 8- and 11-foot parachutes (figure 1), and by free-dropping (figure 2). In addition baled trees were transported by boat and packed overland to the planting site. These trees were to be used as a "control" planting to compare their survival with that of the trees dropped from the aircraft.
