• Maintaining forest biodiversity by combining protection, management and restoration of forest and woodland landscapes is a central component of sustainable development.
• Evidence that there are threshold levels for how much habitat loss may be tolerated for viable populations of specialised species to be maintained.
• Policy-makers, businesses and managers pose questions about how to balance use of renewable forest resources and conserve biodiversity.
• Examples are presented on how biodiversity assessments can be made.
• Proposes how the critical gaps in...

Trees are one of the dominant features of our existence on earth and play a fundamental role in the environment. This book gives the reader an overview and understanding of trees. Subject areas covered include ecology and conservation, tree anatomy and evolution, pathology, silviculture, propagation, and surgery. The different chapters cover trees from various world habitats, from northern boreal and montane coniferous forests to tropical and subtropical rainforests. The book is fully illustrated throughout with the highest quality color photos and is invaluable to professionals and...

Biodiversity is decreasing at the fastest rate in the history of the earth, largely as a result of human activity. The sustainable use of ecosystems allowing maintenance of biological diversity is an urgent problem that must be solved. Among terrestrial ecosystems, forests support the richest biological diversity. The interaction of humans and forests has a long history, but recent changes have been the most drastic ever. The rapid decrease and deterioration of forest ecosystems has been caused by social, economic, and ecological factors, which may vary locally but are common globally. The...

A fascinating work that provides a wealth of information on one of the world's most biodiverse ecosystems. This is the result of investigations by almost 30 groups of researchers from various disciplines. They performed ecosystem analyses following two gradients: an altitudinal gradient and a gradient of land use intensity and ecosystem regeneration following human use. Based on these analyses, this volume discusses these findings in a huge variety of subject areas.

Micropropagation has become a reliable and routine approach for large-scale rapid plant multiplication, which is based on plant cell, tissue and organ culture on well defined tissue culture media under aseptic conditions. A lot of research efforts are being made to develop and refine micropropagation methods and culture media for large-scale plant multiplication of several number of plant species. However, many forest and fruit tree species still remain recalcitrant to in vitro culture and require highly specific culture conditions for plant growth and development. The recent challenges on...

Genome Mapping and Molecular Breeding in Plants presents the current status of the elucidation and improvement of plant genomes of economic interest. The focus is on genetic and physical mapping, positioning, cloning, monitoring of desirable genes by molecular breeding and the most recent advances in genomics. The series comprises seven volumes: Cereals and Millets; Oilseeds; Pulses, Sugar and Tuber Crops; Fruits and Nuts; Vegetables; Technical Crops; and Forest Trees.

Forest trees cover one third of the global land surface, constitute many ecosystems and play a pivotal role in the...

Carbon and Nitrogen in the Terrestrial Environment is a comprehensive, interdisciplinary description of C and N fluxes between the atmosphere and the terrestrial biosphere; issues related to C and N management in different ecosystems and their implications for the environment and global climate change; and the approaches to mitigate emission of greenhouse gases.

Drawing upon the most up-to-date books, journals, bulletins, reports, symposia proceedings and internet sources documenting interrelationships between different aspects of C and N cycling in the terrestrial...

Biological control of plant diseases and plant pathogens is of great significance in forestry and agriculture. There is great incentive to discover biologically active natural products from higher plants that are better than synthetic agrochemicals and are much safer, from a health and environmental point-of-view. The development of natural products such as herbicides, fungicides, and their role in biological control of plant diseases, indicates a reduction in environmental and health hazards. Allelopathic techniques offer a real future in solving several problems, for instance biological...
