Available in PDF, EPUB and Kindle. Book excerpt: At the present time, the position of modern integrated protection of forests menaced by pests is increasing in importance, and not just because of demands on the quality and quantity of wood being raised. It is steadily becoming more necessary to revise the consequences of the often imprudent, although sometimes seemingly effective, chemical control in forest biocoenosis. Additionally, harmful insects are becoming more resistant to pesticides and so increasing the chance of accidentally jeopardizing plants. In the future concept of integrated forest pest control, we may therefore expect the population density of many harmful species to be regulated to a larger degree by biological control. This book discusses the economic importance of insects beneficial to the protection of forest trees, and provides information on their biology. The text and the pictorial section to this book divide beneficial insects into predators and parasites. The first section is devoted to predators, particularly ants, the most frequent insect species found in forests. Scale bugs, groups of predatory beetles, Neuroptera and Diptera are also mentioned. The second part describes parasitic insects. For this reason, representatives of the order Hymenoptera are mentioned twice: in the first section, among predators (ants) and, in the second part, among the parasites (ichneumons, braconids, chalcid-flies and Aphidiids). Similarly, Diptera are listed in the first section under predatory species (robber flies and lonchaeids) and then at the end of the text under parasitic species (tachinid-flies). An index of scientific names of the illustrated species and a short terminology complete the book. The book is intended as a text book for forestry and agricultural schools, and as a reference text for those concerned with the biological protection of forests, i.e. forest researchers, entomologists and biologists.
Download or read book Insects Harmful to Forest Trees written by Rene Martineau and published by . This book was released on 1984 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The insects presented in this book are among the most common and the most destructive found on what are considered to be the most important tree species; namely, spruce, larch, pine, oak, maple and poplar.It is intended for use by both scientists and by practising foresters. To make the information contained in this volume more easily accessible, insects are grouped according to the tree species that they attack rather than by their entomological classification, and, for this reason, insects found on a given tree species are presented in the same chapter. The annual reports of the Forest Insect and Disease Survey have provided most of the information on history of outbreaks that is found in the text.

Download or read book Forest Monitoring written by and published by Newnes. This book was released on 2013-03-16 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for comparable, long-term, high quality data on forest ecosystems' status and changes is increasing at the international and global level. Yet, sources for such data are limited and in many case it is not possible to compare data from different monitoring initiatives across space and time because of methodological differences. Apart from technical manuals, there is no comprehensive multidisciplinary, scientific, peer-reviewed reference for forest monitoring methods that can serve and support the user community. This book provides in a single reference the state-of-the-art of monitoring methods as applied at the international level. The book present scientific concepts and methods that form the basis of the transnational, long-term forest monitoring in Europe and looks at other initiatives at the global level. Standardized methods that have been developed over two decades in international forest monitoring projects are presented. Emphasis is put on trans-nationally harmonized methods, related data quality issues, current achievements and on remaining open questions. A comprehensive overview of needs, requirements, organization and possible outcomes of an integrated monitoring program Tested and quality assured, internationally harmonized methodologies based on a complete revision of existing methods carried out in 2009-2011 Connection with monitoring results allows assessment of the potential of the monitoring method

Book excerpt: “Maloof eloquently urges us to cherish the wildness of what little old-growth woodlands we have left. . . . Not only are they home to the richest diversity of creatures, but they work hard for humans too.” —New York Times Book Review An old-growth forest is one that has formed naturally over a long period of time with little or no disturbance from humankind. They are increasingly rare and largely misunderstood. In Nature’s Temples, Joan Maloof, the director of the Old-Growth Forest Network, makes a heartfelt and passionate case for their importance. This evocative and accessible narrative defines old-growth and provides a brief history of forests. It offers a rare view into how the life-forms in an ancient, undisturbed forest—including not only its majestic trees but also its insects, plant life, fungi, and mammals—differ from the life-forms in a forest manipulated by humans. What emerges is a portrait of a beautiful, intricate, and fragile ecosystem that now exists only in scattered fragments. Black-and-white illustrations by Andrew Joslin help clarify scientific concepts and capture the beauty of ancient trees.
Download or read book Forest Monitoring written by Johannes Eichhorn and published by Elsevier Inc. Chapters. This book was released on 2013-03-16 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assessment and evaluation of tree condition and vitality is an essential part of the ICP Forests monitoring programme. Due to the complex structure of forest ecosystems, a number of different indicators of tree condition are adopted. In this chapter, they are described also in terms of their ecological relevance. Special emphasis is laid on biotic agents affecting forest ecosystems and explaining tree responses to stressors. For operational reasons, definitions and recommendations for the use of the indicators are given. Tree condition assessment in forest monitoring is closely linked to field measures of Quality Assurance and Control. Examples of results show that the methods currently used in tree condition monitoring are sensitive to detect the effects of climate change on forests and identifying main spatial and temporal patterns and damaging agents.
