Book Description
A survey of 61 cutblocks planted since 1964 evaluated stocking of conifers (trees 1 foot tall or taller) on 2-milacre quadrats. Overall stocking percentage averaged 42.2 and ranged from 15 to 8 1. Overall number of trees per acre . averaged 396. In the regression model, based on 36 cutblocks, better stocking was associated with high site class, northerly aspect, elevation below 3000 feet, and tractor (rather than cable) logging. Stocking tended to increase with increasing age of plantation, but decreased with increasing size of cutblocks.

Book Description
Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the regions forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters andperhaps more importantlyto those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.

Book Description
A planting trial was established in 1986 on a clearcut, disc-trenched, well-drained, sandy loam jack pine site near Gogama, Ontario to determine the effect of initial morphology and planting practices on field performance of jack pine bareroot and container stock. Survival and height after six growing seasons are reported for treatments related to initial seedling size and shoot:root ratio, leader dominance, root pruning, microsite selection, and seedling placement.
