Download or read book Protection Strategy against Spruce Budworm written by David A. MacLean and published by MDPI. This book was released on 2020-01-15 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spruce budworm (Choristoneura fumiferana (Clem.)) outbreaks are a dominant natural disturbance in the forests of Canada and northeastern USA. Widespread, severe defoliation by this native insect results in large-scale mortality and growth reductions of spruce (Picea sp.) and balsam fir (Abies balsamea (L.) Mill.) forests, and largely determines future age–class structure and productivity. The last major spruce budworm outbreak defoliated over 58 million hectares in the 1970s–1980s, and caused 32–43 million m3/year of timber volume losses from 1978 to 1987, in Canada. Management to deal with spruce budworm outbreaks has emphasized forest protection, spraying registered insecticides to prevent defoliation and keep trees alive. Other tactics can include salvage harvesting, altering harvest schedules to remove the most susceptible stands, or reducing future susceptibility by planting or thinning. Chemical insecticides are no longer used, and protection strategies use biological insecticides Bacillus thuringiensis (B.t.) or tebufenozide, a specific insect growth regulator. Over the last five years, a $30 million research project has tested another possible management tactic, termed an ‘early intervention strategy’, aimed at area-wide management of spruce budworm populations. This includes intensive monitoring to detect ‘hot spots’ of rising budworm populations before defoliation occurs, targeted insecticide treatment to prevent spread, and detailed research into target and non-target insect effects. The objective of this Special Issue is to compile the most recent research on protection strategies against spruce budworm. A series of papers will describe results and prospects for the use of an early intervention strategy in spruce budworm and other insect management.

Download or read book Algonquin ethnobotany written by Meredith Jean Black and published by University of Ottawa Press. This book was released on 1980-01-01 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: A compilation of published ethnobotanical data pertaining to all of the Algonkian speaking peoples of eastern North America and field data concerning the Algonquin bands of the Ottawa River drainage and the Cree bands of the St. Maurice drainage of western Quebec. These data help illuminate past subsistence patterns, the seasonal movements of the Algonquin, and the relationship between Algonquin bands and other Algonkian speakers. They also indicate that the Algonquin previously enjoyed a subarctic subsistence orientation similar to that of the Cree and other northerners in contrast to their Iroquoian neighbours thus necessitating a redefinition of the eastern subarctic culture area.

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.
