Almost half of all life on earth may exist in the world's forest canopies. They may also play a vital role in maintaining the planet's climate, yet they remain largely unexplored owing to difficulties of access. They are renowned for their great diversity and role in forest functioning, yet there are still great gaps in the understanding of this last biological frontier'. This seminal book shows how canopy science is now in a position to answer many of the outstanding questions, among which are some of the most pressing environmental issues society is presently facing. It represents a major...

Changing environmental conditions substantially affect genetic variation and its dynamics in forest ecosystems and various systems of plantations. In response to these challenges, the present book focuses on the response to stress in terms of case studies which address physiological and genetic characters as well as various metric traits. Furthermore a choice of studies is presented which refers to diversity and geographic variation of various species and site conditions, respectively. In addition, genetic resources are characterised and a variety of studies is compiled which address...

Bioenergy from Sustainable Forestry synthesizes information needed to design or implement sustainable forest management systems for production of biomass for energy in conjunction with other forest products. It is organized around the criteria for sustainable forest management: productivity, environment, social issues, economics, and legal and institutional framework. More than 25 international experts from 10 countries have brought together available ecological, physical, operational, social and economic information and identified gaps in knowledge related to biomass...

This book provides a state-of-the-art review of both classical and emerging themes in forest resource economics. The authors show how neo-classical economic principles can be used to analyze forest policy issues across existing and developing market economies in the United States, Latin America, and South and Southeast Asia. The chapters encompass traditional and modern areas of concern in forest policy, including timber production and markets, multiple use forestry, and valuation of non-market benefits. These topics are developed with case studies that demonstrate rigorous empirical analysis...

Policy issues relating to forestry have been the subject of much debate in recent years, and many countries and international agencies have recently, or are currently in the process, of revising their policies for forestry. Much of this debate has implied that previous policies have failed or been much less successful than had been hoped. There is a tendency to think of policy as a matter for governments, but it is now more widely appreciated that all shareholders in the forestry sector have a legitimate interest in both the policy objectives and the means that will be used to implement...

The papers in this book were 'in a preliminary version' presented at an international con- ference May 21-25, 2002 in Gilleleje, Denmark. It was a joint event, namely the biennial meeting of the Scandinavian Society of Forest Economics and the 3rd Berkeley-KVL Con- ference. The Scandinavian Society of Forest Economics (SSFE) was established in 1958 as a forum for forest economists in the Nordic countries to meet and exchange ideas on research and education. Alternating between Denmark, Finland, Norway and Sweden, biennial ordinary meetings have taken place ever since. The number of...

The increasing awareness and concern of people, researchers and decision makers for the maintenance and enhancement of goods and services provided by forest ecosystems significantly widened the scope of information needs for sustainable forest management on the task-specific, integrative and strategic level. Forest resource assessments have to provide reliable, harmonized, politically relevant, cost-efficient and intuitively visible information on the multiple functions of forests in the form of statistics, georeferenced data and thematic cartography. In this perspective, the need of...

On the occasion of the 50th Anniversary of the International Association of Wood Anatomists several symposia were held during the 13th International Botanical Congress in Sydney, August 1981. Extended versions of most of the invited papers presented there, and some additional papers on aspects which could not be included in the congress program constitute the contents of this book, which intentionally received the pretentious title 'New Perspectives in Wood Anatomy'. To some readers it may seem a paradox that under this heading papers on a diversity of partly traditional wood anatomical...

Roelof A. A. Oldeman Tropical hardwoods are one of the essential cogs in the complex socio-economic machinery keeping alive an ever-increasing humanity with steadily rising claims upon a finite-resource environment. Their position in this context at first sight seems to be analogous to that of other commodities, such as rubber, metals, mineral oil, tropical fruits and many more. Looking closer, however, tropical hardwoods occupy a special place. Their vast majority, unlike tropical crops, still comes forth from natural forests being exploited by man. This exploitation straight from the...
