The International Energy Agency Bioenergy Agreement was initiated as the Forestry Energy Agreement in 1978. It was expanded in 1986 to form the Bioenergy Agreement. Since that time the Agreement has thrived with some fifteen countries (Austria, Belgium, Canada, Denmark, Finland, Italy, Japan, Netherlands, New Zealand, Norway, Sweden, Switzerland, United Kingdom, United States and the CEC) currently being signatories. The objective of the Agreement is to establish increased programme and project cooperation between the participants in the field of bioenergy. The environmental consequences of intensive forest harvesting have been the subject of intense interest for the Agreement from its initiation. This interest was formulated as a Cooperative Project under the Forestry Energy Agreement in 1984. It developed further under each of the subsequent three-year Tasks of the Bioenergy Agreement (Task III, Activity 3 "Nutritional consequences of intensive forest harvesting on site productivity", Task VI, Activity 6 "Environmental impacts of harvesting" and more recently Task IX, Activity 4 "Environmental impacts of intensive harvesting". The work has been supported by five main countries from within the Bioenergy Agreement: Canada, New Zealand, Sweden, UK, and USA. The continued work has resulted in a significant network of scientists work ing together towards a common objective - that of generating a better under standing of the processes involved in nutrient cycling and the development of management regimes which will maintain or enhance long term site productivity.
The group of saproxylic beetles consists of thousands of different species exhibiting a rich variety of form as well as varied life-cycle strategies. They play an important role in decomposition processes and thus for nutrient-cycling in natural ecosystems. Based on contributions given at the conference this book contains contributions about research on conservation ecology of saproxylic beetles as well as results from recent faunistic surveys in different European regions. It comprises aspects of saproxylic beetle ecology, faunistics, diversity and conservation issues. International experts report on their activity, management strategies and new approaches in saproxylic insect conservation. There are a lot of people doing research on saproxylic beetles in different countries of the world, but this seems to be a little bit disorganized. Hopefully, these European conferences will lead to a better, more international network. The contributions included in this volume cover a broad spectrum of research on saproxylic beetles, organized in three main chapters: "Saproxylic beetle assemblages and regional surveys" include "Oaks in Norway," showing the abundance and composition of red-listed species of beetles in hollow oaks. Further reports on regional surveys deals with a spruce primeval forest in Romania, a hardwood floodplain forest in the Czech Republic, and the Gartow region of Lower Saxony, a hotspot of saproxylic beetle diversity in north-western Germany. "Saproxylic beetle ecology and implications for their conservation" deals with ecological studies of single species, e.g. Limoniscus violaceus, Lucanus cervus, Osmoderma eremita and the worldwide distribution of the genus Cucujus. "Advances in methodology and databases" discusses new techniques in trapping and the development of databases. This volume gives a nice overview of the actual research on saproxylic beetles in Europe and I wish the next conference in 2010 a successful meeting; maybe some people from the UK or even overseas should be invited.
A knowledge of forest site and forest productivity variables is fundamental to sound forest practice everywhere. The ability to identify sites and site problems correctly and manipulate productivity variables for maintenance or improvement of productivity is the basis of modern forest management. Although the basic facts regarding forest site and productivity apply throughout the world, the application of information and the response to manipulation vary greatly and depend on local forest conditions. The September 1981 World Congress of the International Union of Forest Research Organizations (IUFRO) in Kyoto, Japan was the occasion for the special meeting on Forest Site and Productivity sponsored by the IUFRO Site Group Sl.02. This meeting brought together forest site and productivity researchers from across the world to review current thought and the state of site research. Information not ordinarily available in one place was presented at this meeting. As organizer of the session, I decided to attempt to publish the papers in one volume. Arrangements were made with a publisher, Martinus Nijhoff, and also with the authors. The process of publication has taken longer than desirable, but the volume does appear at an opportune time coincident with the 1986 IUFRO World Congress in Yugoslavia. Material contained in this publication will set the stage for Site Group discussions at the 1986 meeting. This volume assembles the thought of forest research workers from many different countries and therefore many different kinds of forests.
This new edition has been completely revised to provide up-to-date accounts of silvicultural practices, rural development issues, and the wider role that tree-planting plays. The chapters on agroforestry and protection forestry have been virutally rewritten, while throughout the book theimportant place of social forestry is recognized.
This book is a printed edition of the Special Issue "Urban and Periurban Forest Diversity and Ecosystem Services" that was published in Forests
