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.

This book is a dictionary of British (native, naturalised and cultivated) plants and the folklore associated with them. Unlike many plant-lore publications Vickery's Folk Flora tells us what people currently do and believe, rather than what Victorians did and believed. The result is a vivid demonstration that plant folklore in the British Isles is not only surviving but flourishing; adapting and evolving as time goes by, even in urban areas. Each entry includes: - The plant's English and scientific (Latin) name, as well as significant local names. - A brief description of the plant and its distribution, and, in the case of cultivated plants, a history of their introduction to the British Isles - Information on the folklore and traditional uses of the plant, arranged where possible in a sequence starting with general folk beliefs (superstitions), use in traditional customs, use in folk medicine, other uses, and legends concerning individual representatives of the plant. In addition to the major entries there are a number of minor entries for feast days, diseases and other subjects which direct readers to relevant major entries, e.g. St. George's Day, on which red roses are worn; dandelions are gathered; and runner beans are planted.

This beautiful book is a celebration of the mighty oak, through the passion and vision of artist Mark Frith. Mark has drawn large scale portraits of 22 of Britain's oldest living oaks, with exceptional detail conveyed in these intricate graphite works, bringing the ancient features of these majestic individuals to life on the page. Growing up in the Gloucestershire countryside, Mark enjoyed a childhood experiencing the natural world and in particular developed a huge closeness to a local ancient character - the Great Oak at Nibley Green. Mark would return to this tree in 2010 as the first of his series of oak drawings, commissioned by the publisher, poet, philanthropist and planter of trees Felix Dennis. These large-scale drawings measuring 1.7 m wide took Mark three and a half years to complete and were finished just before Felix Dennis's death in 2014. Following Felix Dennis's wishes, his estate bequeathed 10 of the drawings to the Royal Botanic Gardens, Kew. This stunning book is the ideal gift for art and tree lovers alike, and a fitting dedication to these ancient individuals. I hope that in some modest way these drawings express man's profound relationship with the natural world, and, if it has one, something of the soul of the ancient oak tree. Mark Frith

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.

Field Guide to the Wild Flowers of the Eastern Mediterranean is the most comprehensive and up-to-date plant identification guide to the area. This large area has a complex and varied geology and topography but is united by its typically Mediterranean climate of hot, dry summers and mild, wet winters. The eastern Mediterranean has an exceptionally high number of endemic species, and a flora quite distinct from the western Mediterranean Basin.

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.

"A volume for a lifetime" is how The New Yorker described the first of Donald Culross Peatie's two books about American trees published in the 1950s. In this one-volume edition, modern readers are introduced to one of the best nature writers of the last century. As we read Peattie's eloquent and entertaining accounts of American trees, we catch glimpses of our country's history and past daily life that no textbook could ever illuminate so vividly. Here you'll learn about everything from how a species was discovered to the part it played in our country's history. Pioneers often stabled an animal in the hollow heart of an old sycamore, and the whole family might live there until they could build a log cabin. The tuliptree, the tallest native hardwood, is easier to work than most softwood trees; Daniel Boone carved a sixty-foot canoe from one tree to carry his family from Kentucky into Spanish territory. In the days before the Revolution, the British and the colonists waged an undeclared war over New England's white pines, which made the best tall masts for fighting ships. It's fascinating to learn about the commercial uses of various woods -- for paper, fine furniture, fence posts, matchsticks, house framing, airplane wings, and dozens of other preplastic uses. But we cannot read this book without the occasional lump in our throats. The American elm was still alive when Peattie wrote, but as we read his account today we can see what caused its demise. Audubon's portrait of a pair of loving passenger pigeons in an American beech is considered by many to be his greatest painting. It certainly touched the poet in Donald Culross Peattie as he depicted the extinction of the passenger pigeon when the beech forest was destroyed. A Natural History of North American Trees gives us a picture of life in America from its earliest days to the middle of the last century. The information is always interesting, though often heartbreaking. While Peattie looks for the better side of man's nature, he reports sorrowfully on the greed and waste that have doomed so much of America's virgin forest.

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.

Dieser Band enthalt 27 Fachgutachten aus unterschiedlichen Disziplinen zum Gesamtkomplex "Nachhaltige Land- und Forstwirtschaft." Im Vordergrund stehen dabei Fragen wie: Kann eine nachhaltige Land- und Forstbewirtschaftung unter Einbeziehung okologischer, okonomischer und sozialer Aspekte erreicht werden? Was bedeutet dies fur unsere Kulturlandschaft? Welche politischen und betriebswirtschaftlichen Rahmenbedingungen sind erforderlich, um einerseits die Umweltbelastungen zu senken und andererseits die Wettbewerbsfahigkeit langfristig zu gewahrleisten? Welche Chancen bieten hierfur neue Technologien und Markte? Eine kurzgefasste Synthese aus diesen Untersuchungen erschien unter dem Titel "Nachhaltige Land- und Forstwirtschaft: Voraussetzungen, Moglichkeiten, Massnahmen.""

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."
