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.

Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Poplars and willows form an important component of forestry and agricultural systems, providing a wide range of wood and non-wood products. This book synthesizes research on poplars and willows, providing a practical worldwide overview and guide to their basic characteristics, cultivation and use, issues, problems and trends. Prominence is given to environmental benefits and the importance of poplar and willow cultivation in meeting the needs of people and communities, sustainable livelihoods, land use and development.

The seashore has long been the subject of fascination and study - the Ancient Greek scholar Aristotle made observations and wrote about Mediterranean sea urchins. The considerable knowledge of what to eat and where it could be found has been passed down since prehistoric times by oral tradition in many societies - in Britain it is still unwise to eat shellfish in months without an 'r' in them. Over the last three hundred years or so we have seen the formalization of science and this of course has touched intertidal ecology. Linnaeus classified specimens collected from the seashore and many common species (Patella vulgata L. , Mytilus edulis L. , Littorina littorea (L. )) bear his imprint because he formally described, named and catalogued them. Early natural historians described zonation patterns in the first part of the 19th century (Audouin and Milne-Edwards, 1832), and the Victorians became avid admirers and collectors of shore animals and plants with the advent of the new fashion of seaside holidays (Gosse, 1856; Kingsley, 1856). As science became professionalized towards the end of the century, marine biologists took advantage of low tides to gain easy access to marine life for taxonomic work and classical studies of functional morphology. The first serious studies of the ecology of the shore were made at this time (e. g.
