DOWNLOAD EBOOKThis bibliography was produced to assist foresters and scientists interested in modelling boreal forest succession at broad scales. It contains more than 600 citations describing existing knowledge on succession in North American boreal forests, and the current state-of-knowledge in modelling succession, with particular emphasis on broad scales. References on succession in boreal forests are grouped by geographic and taxonomic categories. This bibliography also provides information on theories and concepts of succession modelling, issues of scale in modelling succession, the spatial process of propagule dispersal, and the probalistic modelling of forest succession. An author index is provided to help users located citations of interest.

DOWNLOAD EBOOKSilviculture activities, comprising site preparation, planting, direct seeding, stand tending, and pest control, are summarized for each province and territory and for Canada for 1975-76 to 1985-86. Silviculture activities have increased steadily relative to the area harvested. The basic area data on site preparation, planting, and direct seeding have been further refined with more complete information on site preparation application and silviculture success rates. Information on success rates indicates that approximately 68% of the area harvested is adequately reforested, with natural regeneration accounting for 74% of this reforestation. Stand tending has increased more than any other silviculture activity.
