Conifers are one of the world's most important resources of timber. If managed wisely and used sustainably, these resources will provide wood for a multitude of purposes, virtually indefinitely. Additional products include resins and their derivatives, and even medicinal extracts--for example taxol now used in the treatment of cancer. Conifers occur on all continents except Antarctica. Of the 630 species, 355 are listed as of conservation concern, with 200, or 25 of species, threatened with extinction. Although exploitation of these resources is as old as civilization, this century has seen a dramatic increase in the exploitation of timber resources. This action plan assess conifer diversity and its threats. It is unique among IUCN's Plant Action Plans so far published, in that it gives the complete global red list of conifers using the 1994 IUCN Red List Categories and criteria. Data is analyzed to identify .conifer hot spots., where conservation should be a priority, and a short-list of threatened species is prioritized.

"Conifers, the most underrated plants in the landscape world, provide the garden with strong form, color and texture in each season. These versatile low-maintenance plants come in an array of shapes other than the ubiquitous pyramid and in umpteen colors - yellows, blues, grays and maroons. This essential guide will help you select the conifers that will set your garden's stage - every day of the year."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

As an introduction to the present book I would like to explain how it was, that I, a commercial nurseryman, became so keenly interested in Conifers and their nomen clature. In August 1924 the Dutch Dendrological Society was founded and at the same time a Committee for Nomenclature of woody plants was set up and I served on this committee as one of the members. Our first activity was to bring the catalogues of the various leading nurserymen in the Netherlands into line with the International Rules of Botanical Nomenclature and also to check their nursery stock. Formerly these catalogues had shown a rather confused nomenclature, nurserymen having usually made use of a variety of inconsistent books as guides in compiling their catalogues. In the course of the work a close co-operation between scientific and practical workers developed. Although I had also fully contributed to the correct naming of hardy shrubs and perennials, 1 was most interested in Conifers. I had tried out several species, had grown a wide choice of garden forms and selected types of particular merit for propagation. My special love for Conifers lead to the publication of my Name-list of Conifers (1937), which was adopted as a standard for varietal names at the International Horticultural Congress in Berlin (1938). Later I prepared my book 'Coniferen, Ephedra en Ginkgo' in the Dutch language (1949); compiling the Conifers cultivated or known to be grown in the Netherlands and Belgium at that time.

This useful manual provides a means for easy identification of the native and cultivated conifers of northeastern North America. The territory covered is roughly eastern Canada and the northeastern fourth of the United States, from Maine south to the southern border of Pennsylvania, west to Kansas, and north to North Dakota. Because it includes so many cultivated species, the book treats the great majority of conifers found in the western United States and Europe as well. Twenty-seven genera and 130 species are included.

Coniferous forests are among the most important of ecosystems. These forests are widespread and influence both the financial and biological health of our globe. This book focuses attention on conifers and how these trees acquire, allocate, and utilize the resources that sustain this crucial productivity. An international team of experts has surveyed and synthesized information from an expanding area of inquiry. The first half of the book describes how resources are acquired both by means of photosynthesis and through root systems. The latter half of the volume focuses upon how resources are stored and used. As conifers continue as a resource and ever increasingly important contributor to the regional and global environmental sustainability, this book will help establish how much sustainability can be expected and maintained.

Conifer Cold Hardiness provides an up-to-date synthesis by leading scientists in the study of the major physiological and environmental factors regulating cold hardiness of conifer tree species. This state-of-the-art reference comprehensively explains current understanding of conifer cold hardiness ranging from the gene to the globe and from the highly applied to the very basic. Topics addressed encompass cold hardiness from the perspectives of ecology, ecophysiology, acclimation and deacclimation, seedling production and reforestation, the impacts of biotic and abiotic factors, and methods for studying and analyzing cold hardiness. The content is relevant to geneticists, ecologists, stress physiologists, environmental and global change scientists, pathologists, advanced nursery and silvicultural practitioners, and graduate students involved in plant biology, plant physiology, horticulture and forestry with an interest in cold hardiness.

Atlas of Nevada Conifers is a major scientific contribution to our understanding of the ecology of Nevada. It documents in great detail the distribution of all native conifer species in the state--critical information because of the primary ecological importance of conifers for all organisms and because of the lack of documentation of these distributions in the scientific literature before now. Charlet maps and documents the exact location of herbarium records for 1,600 individual trees. The data found in 23 tables and 22 range maps will serve as a primary reference for botanists, land managers, and conservation biologists for years to come.
