After an introduction on stand thinning objectives and methods, this report gives an overview of the habitat and growth characteristics of jack pine and presents a literature review of jack pine thinning. Research needs regarding thinning operations in Ontario and management considerations for jack pine are also outlined. The report concludes with a case study conducted to demonstrate commercial thinning of jack pine with a single grip harvester. The study was carried out at the Seine River Demonstration Forest in north-west Ontario.

ISBN:

Begins with a literature review on the habitat, reproduction, seedbed requirements, and growth of black spruce, and continues with an overview of black spruce silvicultural systems for Ontario upland sites. Research needs and management considerations are then outlined. Concludes with reports on two case studies of black spruce silviculture at the Leo Vidlak Demonstration Forest near Raith, Ontario. The first study involved two-stage harvesting as an alternative to clear-cutting, and the second explored natural regeneration in stands without advance growth.

Fall and spring planting and seeding of jack pine and fall seeding of white spruce were operationally tested on four burned, clear-cut areas in central Saskatchewan. Hand planting of conventional nursery stock at 1.8 m spacing and uniform broadcast seeding of 0.56 kg of seeds (viability 65%) per hectare were the standard postburn treatments. Tree regeneration that followed the various postburn operation treatments was surveyed in late August and early September 1979. Heights of dominant jack pines were measured again in October 1985 to obtain a rough assessment of their growth performance. The 1979 regeneration was assessed by species and groups of species for stocking, density, and height.
