Ecology And Management Of Sitka Spruce

Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.

This book takes a fresh look at the most disliked tree in Britain and Ireland, explaining the reasons it was introduced and why it became ubiquitous in the archipelagos of northwest Europe. Sitka spruce has contributed to the Pacific Coast landscapes of North America for over ten millennia. For the Tlingit First Nation it is the most important tree in terms of spiritual relationships, art, and products in daily use such as canoes, containers, fish-traps and sweet cakes. Since the late nineteenth century it has also been the most important tree to the timber industry of west coast North America. The historical background to the modern use of Sitka spruce is explored. The lack of cultural reference may explain negative public response when treeless uplands in the UK and Ireland were afforested with introduced conifer species, particularly Sitka spruce, following two World Wars. The multipurpose forestry of today recognizes that Sitka spruce is the most important tree to the timber industry and to a public which uses its many products but fails to recognize the link between growing trees and bought goods. The apparently featureless and wildlife-less Sitka spruce plantations in UK uplands are gradually developing recognizable ecological features. Sitka spruce has the potential to form temperate rain forests this century as well as to produce much-needed goods for society. The major contribution of Sitka spruce to landscapes and livelihoods in western North America is, by contrast, widely accepted. But conserving natural, old-growth forests, sustaining the needs of First Nations, and producing materials for the modern timber industry will be an intricate task.

This book provides an up-to-date synthesis of the understanding of the interaction between the emission of nitrogen, its deposition and impact on the most important components of natural and semi-natural ecosystems. The work consists of contributions from internationally renowned research scientists. Individual chapters deal with the factors and processes related to nitrogen deposition and soils, non-forest vegetation communities, forest ecosystems, and surface waters. The assessment of these impacts is discussed in terms of setting critical loads. The book is aimed at researchers, advanced course students and policy makers/advisors involved with aspects of the impact of air pollution.

Guitars inspire cult-like devotion: an aficionado can tell you precisely when and where their favorite instrument was made, the wood it is made from, and that wood’s unique effect on the instrument’s sound. In The Guitar, Chris Gibson and Andrew Warren follow that fascination around the globe as they trace guitars all the way back to the tree. The authors take us to guitar factories, port cities, log booms, remote sawmills, Indigenous lands, and distant rainforests, on a quest for behind-the-scenes stories and insights into how guitars are made, where the much-cherished guitar timbers ultimately come from, and the people and skills that craft those timbers along the way. Gibson and Warren interview hundreds of people to give us a first-hand account of the ins and outs of production methods, timber milling, and forest custodianship in diverse corners of the world, including the Pacific Northwest, Madagascar, Spain, Brazil, Germany, Japan, China, Hawaii, and Australia. They unlock surprising insights into longer arcs of world history: on the human exploitation of nature, colonialism, industrial capitalism, cultural tensions, and seismic upheavals. But the authors also strike a hopeful note, offering a parable of wider resonance—of the incredible but underappreciated skill and care that goes into growing forests and felling trees, milling timber, and making enchanting musical instruments, set against the human tendency to reform our use (and abuse) of natural resources only when it may be too late. The Guitar promises to resonate with anyone who has ever fallen in love with a guitar.

Large-scale use of the timber resource of southeast Alaska began in 1953 after long efforts to establish a timber industry. Development and present status of the industry and present management of the timber resource are summarized, stressing the biological basis for timber management activities in southeast Alaska today. Ecological and silvicultural considerations related to timber harvest, reforestation, and stand development are discussed. Published and unpublished information are brought together. Current management practices are discussed as a basis for a better understanding of how this information can be helpful in managing the timber resource and to point out where research is needed.
