Results of a 1980-81 national forest tree seed survey are presented. Jack pine, white spruce, and black spruce are by far the most important and widely used reforestation species in Canada, accounting for approximately 59, 22 and 6% of total seed used in reforestation, respectively. Based on the 5.7 billion seeds currently utilized in the nation’s reforestation programs, seed usage needs to be increased by less than 4% per year to meet projected reforestation requirements up until 1987. Procurement programs on a Canadian scale are providing sufficient seed reserves for most major species. Over 88% of seed of major reforestation species originated from unimproved natural stands, slightly onver 11% came from seed collection and production areas, and only 0.2% was collected from seed orchards.
