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.

With contributions by internationally reputed researchers in the field, this book presents the implications of the genomic revolution for conifers—promoting a better understanding of the evolution of these organisms as well as new knowledge about the molecular basis of quantitative trait variation. Both of these discoveries play important roles in their domestication. Topics include cytogenetics, patterns of nucleotide diversity, genetic mapping, integration of molecular markers in breeding, transcriptomics, advances in proteomics and metabolomics in gymnosperms, and economic importance.

Temperate rainforests are biogeographically unique. Compared to their tropical counterparts, temperate rainforests are rarer and are found disproportionately along coastlines. Because most temperate rainforests are marked by the intersection of marine, terrestrial, and freshwater systems, these rich ecotones are among the most productive regions on Earth. Globally, temperate rainforests store vast amounts of carbon, provide habitat for scores of rare and endemic species with ancient affinities, and sustain complex food-web dynamics. In spite of their global significance, however, protection levels for these ecosystems are far too low to sustain temperate rainforests under a rapidly changing global climate and ever expanding human footprint. Therefore, a global synthesis is needed to provide the latest ecological science and call attention to the conservation needs of temperate and boreal rainforests. A concerted effort to internationalize the plight of the world’s temperate and boreal rainforests is underway around the globe; this book offers an essential (and heretofore missing) tool for that effort. DellaSala and his contributors tell a compelling story of the importance of temperate and boreal rainforests that includes some surprises (e.g., South Africa, Iran, Turkey, Japan, Russia). This volume provides a comprehensive reference from which to build a collective vision of their future.

The book is a fundamental reference source on reaction wood for wood scientists and technologists, plant biologists, silviculturists, forest ecologists, and anyone involved in the growing of trees and the processing of wood. It brings together our current understanding of all aspects of reaction wood, and is the first book to discuss both compression wood and tension wood. Trees produce reaction wood to maintain the vertical orientation of their stems and the optimum angle of each branch. They achieve this by laying down fibre cell walls in which differences in physical and chemical structure from those of normal fibres are expressed as differential stresses across the stem or branch. This process, while of obvious value for the survival of the tree, causes serious problems for the utilisation of timber. Timber derived from trees containing significant amounts of reaction wood is subject to dimensional instability on drying, causing twisting, bending and splitting. It is also difficult to work as timber, and for the pulp and paper industry the cost of removing the increased amount of lignin in compression wood is substantial. This has both practical and economic consequences for industry. Understanding the factors controlling reaction wood formation and its effect on wood structure is therefore fundamental to our understanding of the adaptation of trees to their environment and to the sustainable use of wood. The topics covered include: -Morphology, anatomy and ultrastructure of reaction wood -Cell-wall polymers in reaction wood and their biosynthesis -Changes in tree proteomes during reaction wood formation -The biomechanical action and biological functions of reaction wood - Physical and mechanical properties of reaction wood from the scale of cell walls to planks -The detection and characterisation of compression wood -Effects of reaction wood on the performance of wood and wood-based products - Commercial implications of reaction wood and the influence of forest management on its formation

Over 50 per cent of current planting of upland forest in the UK is Sitka spruce. Major areas of research on this species has sought to increase growth rates and timber yields, mainly through making genetically improved planting stock available to the forest grower. This publication is comprised of edited presentations made at a meeting in Elgin in 1990. Each paper addresses a separate issue relevant to the development of one of the most important species in upland forestry at the present time.

British woodlands and forests are often located on sites and in regions that are marginal for agriculture; many are at high elevations and exposed, with short growing seasons. Wherever forests are located, site and climatic conditions must dictate species choice in forest management. This book provides a detailed guide to the biological suitability of different sites and soils for all important native trees and the most extensively used exotics. Apart from physical difficulties such as steepness and stoniness, forest soils also frequently have problems associated with them. They can be waterlogged or drought-prone, suffer from extremes of acidity or alkalinity, or have compacted layers. The book provides information on species' suitability for different purposes. It includes details of species' origin and introduction (where applicable), as well as their climatic and soil requirements and other silvicultural characteristics. Information about provenance, yield and timber is also provided. Fully updated throughout, this 3rd edition puts more emphasis on species suitable for changing climatic conditions, with accounts of several species that may become more prominent in British forests: including several silver firs, hickories, eucalypts, spruces, poplars and wingnuts. The book concludes with simple keys for identifying the trees most likely to be encountered in British forests. It is an essential resource for students, researchers and forestry professionals.
