World Checklist and Bibliography of Conifers by Aljos Farjon Pdf
The definitive reference for botanists, horticulturists, foresters and conservationists - this second edition has been fully revised, and provides the most authoritative listing of conifer names through to the year 2000, with extensive information on distribution, conservation status and a bibliography of the most relevant scientific literature.
The new edition of this work first published in 1990 includes 3,787 references to the published literature. To make it far more accessible, many more general titles have been added including coverage of Araucariaceae, Cupressaceae and Pinaceae and subjects related to their taxonomy.
"What are the lives of trees, of conifers, like'. . . How do seedlings establish and develop into saplings? How do some seedlings stay alive for decades, marking time in the deep shade of the forest? How do the distinctive forms of saplings of the different species arise'. . . When, how, and where do cones come from? What is the sex life of a conifer? Where does pollen come from? What does pollen do?" - From the Introduction A comparative account of the coniferous trees indigenous to Northeastern North America Extensively illustrated with full-colour photographs, diagrams, and drawings by the author, Graham R. Powell's Lives of Conifers examines the complex and fascinating life cycles of the 12 coniferous trees that grow naturally in northeastern North America on both sides of the Canada-U.S. border. Tracing their development from seeds and seedlings, to saplings, through the pole stage to maturity, old age, and death, the book is designed to pro-vide a comparison of each species at each stage of life, thus aiding in the recognition and identification of species at all stages of their existence. It includes descriptions of developmental processes and how they differ among the species. The species covered in the book are: the balsam fir, eastern hemlock, tamarack larch, eastern white pine, jack pine, pitch pine, red pine, black spruce, red spruce, white spruce, eastern juniper, and eastern thuja. The book is based almost entirely on what is visible to the careful observer in the forest, and includes only the parts of trees that can be seen above ground. Lives of Conifers will appeal to forest scientists, forestry students, foresters, forest technologists, botanists, horticulturists, arborists, naturalists, and general readers interested in knowing more about their natural surroundings.
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.
Horticultural Flora of South-eastern Australia: Ferns, conifers & their allies by Roger Spencer Pdf
Cultivated plants are the basis of a vast economic and recreational industry. This book provides an inventory of the large number of plants (both native and exotic) that are cultivated in gardens. It includes accurate, up to date nomenclature and, above all an accessible botanically authorative means of plant identification.
A Handbook of the World's Conifers by Aljos Farjon Pdf
The first handbook to include detailed information on all 615 conifers, temperate as well as tropical, this encyclopedic work offers users as diverse as ecologists, gardeners, foresters and conservationists the accumulated knowledge of these trees obtained in 30 years of academic research, presented in an easily searchable format.
An Atlas of the World's Conifers by Aljos Farjon,Denis Filer Pdf
A 2014 Choice Magazine "Outstanding Academic Title" An Atlas of the World's Conifers is the first ever atlas of all known conifer species. It is based on locality information of ca. 37,000 collected herbarium specimens held in scientific institutions. As well as providing natural distribution maps for each species, Farjon and Filer give the reader comprehensive insight into the biogeography, diversity and conservation status of conifers on all continents, dispelling the widely held view that they are primarily a northern boreal plant group. Conifer diversity is analysed and presented with a taxonomic and geographic perspective. Distribution patterns are interpreted using the latest information on continental drift, dispersal and phylogeny. The entire dataset supporting the Atlas can be consulted and verified online. These data can also be used for further research and are an invaluable resource for anyone working on conifer systematics, biogeography or conservation. An Atlas of the World’s Conifers indicates the known distribution of all conifers including an analysis of their biogeography, diversity and conservation status. Also available from Brill is Aljos Farjon’s A Handbook of the World's Conifers, published in 2010 (ISBN 978 90 04 17718 5) which is a 2017 Choice Magazine "Outstanding Academic Title".
