The CABI Encyclopedia of Forest Trees provides an extensive overview of 300 of the world's most important forest trees. Tropical, subtropical, temperate and boreal trees of major economic importance are included, covering tree species used in agroforestry practices around the world. Many of the species covered are considered to be 'multipurpose' trees with uses extending beyond timber alone; the land uses such as watershed protection or provision of windbreaks, and non-wood uses such as the production of medicines, resins, food and forage, are also listed. Comprehensive information is presented on each tree's importance, with a summary of the main characteristics of the species, its potential for agroforestry use and any disadvantages it possesses. The tree's botanical features such as habit, stem form, foliage, inflorescence, flower and fruit characters and phenology are covered in detail with over 70 colour plate pictures to aid identification. Also included are specific sections devoted to pests and diseases, distribution and silvicultural characteristics and practices, including seed sowing, nursery care, planting, thinning, and harvesting. In addition to the wealth of information detailed, based on datasheets from CABI's Forestry Compendium, selected references for further reading are provided for each entry, making this book an essential reference work for forestry students, researchers and practitioners.

Fur die vierte Auflage haben die unten genannten Verfasser wieder ihre be- sonderen Erfahrungen und Kenntnisse auf einzelnen Teilgebieten zur Verfugung gestellt. Ich moechte ihnen allen an dieser Stelle meinen besten Dank fur ihre wert- volle Mitarbeit zum Ausdruck bringen. Die in den letzten zehn Jahren auf verschiedenen Gebieten eingetretene rasche Entwicklung der Technik, zum Teil verursacht durch den Mangel an Arbeits- kraften in der Landwirtschaft und die dadurch bedingte Mechanisierung, hat dazu gefuhrt, dass die folgenden Abschnitte fast ganz neu bearbeitet werden mussten: Bodenkunde ohne Biologie des Bodens und Humusboeden (Privatdozent Dr. H. WOLKEWITZ, Berlin), Unterhaltung der Bache und Graben, Dranung der Marschboeden (Dr.-Ing. E. h. H. SCHMIDT, Sud-Edewecht), Flussregelung und Flussdeiche (Prof. Dr.-Ing. F. ZIMMERMANN, Braunschweig), Dranung ohne Marsch- und Moorboeden (Reg.-Baudirektor H. L.AIER, Bay- reuth), Maschinentechnischer Teil der Schoepfwerke (Prof. Dr.-Ing. M. PEKRUN, Braun- schweig), Moorkultur (Prof. Dr. W. BADEN, Kulturbaumeister R. EGGELSMANN und Privatdozent Dr. H. KUNTzE, Bremen).

Der Wald ist die machtvollste Entfaltung pflanzlichen Lebens auf der Erdfeste, machtvoll nicht nur im Bild seiner auBeren Er- scheinung, machtvoll vor allem in der unaufhaltsamen Gewalt der Durchsetzung gegenuber anderen Pflanzengesellschaften. Oberall dort, wo die Bedingungen des Makroklimas Baumen ein dauern- des Gedeihen erlauben, verdrangt Wald fruher oder spater die Grasflur, die Heide, das Buschland, erobert er die yom Menschen nicht mehr verteidigten Ackerfluren zuruck, lost sie ab und be- hauptet dann seine Herrschaft. Freilich braucht der Wald ein MindestmaB an Feuchtigkeit und eine zusammenhangende frostfreie Vegetationszeit von minde- stens 60 Tagen im Jahr mit mindestens +IOOC mittlerer Tages- temperatur. Nur unterhalb dieser Grenzen haben Nicht-Wald- Formationen eine sichere Chance, dauernd beherrschend zu blei- ben als Prarie, Steppe, Tundra, Heide oder Dornbusch. Zwar konnen auch innerhalb der Waldklimax - und zwar be- sanders an ihren Grenzen - immer wiederkehrendes Bodenfeuer, Versumpfung, Versalzung, Sanduberwehung und Erosion an steilen Felshiingen den Wald jahrzehnte-, ja jahrhundertelang am FuBfassen hindern. Aber in cler Regel setzt er sich auch hier zu- letzt durch, nachdem Gruppen besonders harter und genugsamer Bodenpflanzen und Straucher, sog. "Pioniergesellschaften", ihm den Boden bereiteten. Dem Wald als Vegetationsform gibt der "Baum" sein augen- falliges Geprage. Ein Baum ist eine Pflanze mit verholzendem Stamm, die eine Scheitelhohe von mindestens 5 m erreichen kann.

'Breathtakingly beautiful' i 'Tender and wholehearted' Helen Jukes LONGLISTED FOR THE WAINWRIGHT PRIZE A BEST BOOK OF THE YEAR IN THE INDEPENDENT, FINANCIAL TIMES, I and GARDENS ILLUSTRATED When she suddenly finds herself uprooted, heartbroken, grieving and living out of a suitcase in her late twenties, Alice Vincent begins planting seeds.

Schwermetalle sind von Natur aus in allen Boeden vorhanden. Die jeweiligen Gehalte sind dabei abhangig von den in den bodenbildenden Ausgangsgesteinen vorhandenen Konzentrationen, von den chemischen Eigenschaften der einzelnen Schwermetalle und von der Entwicklungsgeschichte der Boeden. Von einer wirklichen Belastung fur den Boden kann daher nur bei zusatzlich anthropogen verursachtem Schwermetalleintrag gesprochen werden. Der erste Teil des Buches fuhrt in die naturlichen Bodenprozesse sowie in die Chemie der Metalle und deren Analytik ein. Der Hauptteil beinhaltet detaillierte Informationen zu den einzelnen Schwermetallen, deren spezifischen Wechselwirkungen mit Boeden und Pflanzen und zeigt Moeglichkeiten der Melioration bzw. Sanierung auf.

Weeds are botanical thugs, but they have always been essential to our lives. They were the first crops and medicines and they inspired Velcro. They adorn weddings and foliate the most derelict urban sites. With the verve and historical breadth of Michael Pollan, acclaimed nature writer Richard Mabey delivers a provocative defense of the plants we love to hate.

In this book, Dan Torre explores the intriguing and multifaceted natural, cultural and social history of the orchid. Orchids are one of the largest families of plants - approximately 8 per cent of all the Earth's flowering species. They are known for their beautiful flowers with bright colours, delicate forms and delicate fragrances. However, when we look deeper into their world, we find that they are much more than an elegant flowering plant and behave in unexpected ways that no other flowers do. Philosophers have contemplated them; countless artists have celebrated them; millions of people have cultivated them, displayed them and even consumed them. Orchids occupy our thoughts, our stories, our societies, our greenhouses, our florists, our supermarkets and our homes. And that is merely the beginning.

Leaves are all around us in backyards, cascading from window boxes, even emerging from small cracks in city sidewalks given the slightest glint of sunlight. Perhaps because they are everywhere, it's easy to overlook the humble leaf, but a close look at them provides one of the most enjoyable ways to connect with the natural world. A lush, incredibly informative tribute to the leaf, Nature's Fabric offers an introduction to the science of leaves, weaving biology and chemistry with the history of the deep connection we feel with all things growing and green. Leaves come in a staggering variety of textures and shapes: they can be smooth or rough, their edges smooth, lobed, or with tiny teeth. They have adapted to their environments in remarkable, often stunningly beautiful ways from the leaves of carnivorous plants, which have tiny "trigger hairs" that signal the trap to close, to the impressive defense strategies some leaves have evolved to reduce their consumption. (Recent studies suggest, for example, that some plants can detect chewing vibrations and mobilize potent chemical defenses.) In many cases, we've learned from the extraordinary adaptations of leaves, such as the invention of new self-cleaning surfaces inspired by the slippery coating found on leaves. But we owe much more to leaves, and Lee also calls our attention back to the fact that that our very lives and the lives of all on the planet depend on them. Not only is foliage is the ultimate source of food for every living thing on land, its capacity to cycle carbon dioxide and oxygen can be considered among evolution's most important achievements and one that is critical in mitigating global climate change. Taking readers through major topics like these while not losing sight of the small wonders of nature we see every day if you'd like to identify a favorite leaf, Lee's glossary of leaf characteristics means you won't be left out on a limb Nature's Fabric is eminently readable and full of intriguing research, sure to enhance your appreciation for these extraordinary green machines.

Erstmals in der deutsch- und englischsprachigen Literatur werden - im Gegensatz zu fruheren Werken - bei der Darstellung der Resistenz von Kulturpflanzen gegen tierische Schaderreger sowohl Nematoden, als auch Milben, Insekten und Warmblutler berucksichtigt. Wurde bisher das Stoffgebiet kulturpflanzenspezifisch behandelt, liegt der Schwerpunkt des vorliegenden Buches auf den vielfaltigen Wechselbeziehungen zwischen Schaderreger und Pflanze sowie weiteren Komponenten des Pathosystems. Den Betrachtungen zur Resistenz liegt erstmalig eine Aufgliederung des Komplexes in verschiedene Aspekte zugrunde. Dieses Buch wendet sich an Forscher und Studenten auf dem Gebiet des Pflanzenschutzes, der Pflanzenzuchtung und der Phytopathologie."
