This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Red spruce (Picea rubens) is an important species in northeastern North America. Climate change impacts on this species are expected to vary regionally. We use two historic provenance trials to evaluate red spruce's capacity to persist under climate change by analyzing measurements of tree height and diameter in relation to differences between provenance origin climate and test site climate. Within the range of climate differentials, warming did not appear to negatively impact red spruce performance, but cooling did affect performance by reducing height and diameter. Warmer temperatures increased tree size, especially for northern provenances, suggesting red spruce at the northern extent of its range is cold suppressed. Furthermore, changes in frost free period and mean annual temperature significantly impacted tree size. Temperature-related climatic factors had stronger effects than moisture-related factors. Our tests of climatic effects on more southerly provenances were limited by lack of sites south of red spruce's range

This book was released on 1986 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: A provenance trial of white spruce in the boreal forest of Newfoundland consisting of seed from the Great Lakes - St. Lawrence Forest Region wasmeasured at 25 years from seed. Provenances from selected locations in theOttawa Valley and Quebec were consistently superior in growth over time andon different sites and are recommended for reforestation purposes in Newfoundland.

Download or read book Boreal Forests in the Face of Climate Change written by Miguel Montoro Girona and published by Springer Nature. This book was released on 2023-03-01 with total page 859 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the recent decline of red spruce and the role of acid rain and associated air pollutants in this decline. The purpose of the book is to summarize a large body of recent research on this important environmental issue. The book is divided into 3 sections: Section I summarizes the features of spruce-fir forests in the Eastern U.S. and examines the ecology of the forests, their soils, and the atmospheric conditions experienced by these forests. Section II looks at experimental results from many air pollution studies and evaluates mechanisms of air pollution effects on red spruce trees. Section III synthesizes the current state of knowledge regarding the widespread red spruce decline in forests of the eastern United States.
