Forest regeneration is a cornerstone of managing forests sustainably. Prompt and efficient regeneration gives society the benefits of wood products, as well as the economic wealth that obtaining and processing wood creates. Good reforestation habits provide more wood from less land and increased timber productivity means that demand for wood products can be met with less impact on non-wood uses of the forest. This symposium which was attended by nearly 200 professionals included participants from Canada, the United States, Europe, and Asia had as its focus the issue of forest regeneration which is a cornerstone of managing forests sustainably. Papers presented cover a range of topics related to reforestation within the broader categories of: the status of reforestation and afforestation around the world; nursery methodologies to produce target seedlings; planting and planting site treatments to optimize regeneration; and enhancing timber production and non-timber values through stand establishment.--Document.
