Book Description
An experiment begun in 1955 to test various cutting methods to induce regeneration in mature upland black spruce (Picea mariana [Mill.] B.S.P.) stands in western Manitoba indicated regeneration failure for five cutting methods. To improve seedbeds, bulldozer blade scarification (scalping) was carried out 5 years later. This report deals with regeneration stocking and density (in terms of 4-, 5-, and 10-m2 quadrats) 29 years after logging and 24 years after scarifying. The results showed that using cutting techniques without seedbed treatment was ineffective in promoting adequate regeneration, but scarified seedbeds were well stocked. Severe damage to the residual stand indicates a need to scarify early followed by harvesting of the residual stand. Alternate strip or small-sized block clear-cutting (15 ha in size) followed by immediate scarification is recommended.

Book Description
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.

Book Description
This open access book explores a new conceptual framework for the sustainable management of the boreal forest in the face of climate change. The boreal forest is the second-largest terrestrial biome on Earth and covers a 14 million km2 belt, representing about 25% of the Earth’s forest area. Two-thirds of this forest biome is managed and supplies 37% of global wood production. These forests also provide a range of natural resources and ecosystem services essential to humanity. However, climate change is altering species distributions, natural disturbance regimes, and forest ecosystem structure and functioning. Although sustainable management is the main goal across the boreal biome, a novel framework is required to adapt forest strategies and practices to climate change. This collaborative effort draws upon 148 authors in summarizing the sustainable management of these forests and detailing the most recent experimental and observational results collected from across the boreal biome. It presents the state of sustainable management in boreal forests and highlights the critical importance of this biome in a context of global change because of these forests' key role in a range of natural processes, including carbon sequestration, nutrient cycling, and the maintaining of biodiversity. This book is an essential read for academics, students, and practitioners involved in boreal forest management. It outlines the challenges facing sustainable boreal forest management within the context of climate change and serves as a basis for establishing new research avenues, identifying future research trends, and developing climate-adapted forest management plans.
