Broadcast Seedings From Helicopters in Ontario

Since 1962 the Ontario Department of Lands and Forests has been conducting broadcast tree-seeding trials using helicopters. (1) An effective device, the Brohm aerial seeder, was developed by Department researchers for quick and easy mounting on Bell 47 series models (fig. 1) ; it is also adaptable to many other types of helicopters. This seeder can evenly dispense specified quantities of seed per acre of commercially important Ontario coniferous tree species, such as black and white spruce, d white, red, and jack pine. Since 1962 the design d materials for the seeder have been improved many times. A model is now being developed for light, fixedwing aircraft; it will be used where landing strips are available.
