Twenty-six experimental burns on fresh to moist clear-cut sites in central Saskatchewan were broadcast seeded with jack pine (Pinus banksiana Lamb.) to test single (0.49 kg/ha) arid double (0.98 kg/ha) seeding rates in the spring, with a limited provision for reseeding in the autumn. After four growing seasons, jack pine regeneration from the various seeding treatments was consistently better on burns within small (<2.5 ha) clear-cut areas than on burns within a large (>350 ha) clear-cut area. Doubling the amount of seed sown in the spring substantially increased the regeneration of pine, but reseeding other burns to a double quantity in the autumn was less effective. The beneficial effects of the burning and seeding treatments, however, were grossly negated by the abnormally wet weather during parts of the second and the third postcut growing seasons; consequently, pine regeneration was just as good or better on the undisturbed controls.
