Book Description
This second volume of the magnificent compendium exhaustively describes and classifys the ferns, fern allies, and gymnosperms of North America. Covering over two dozen fern and half a dozen gymnosperm families, they survey fern species of both ecological and horticultural importance and review such gymnosperm taxa as the conifers (the dominant trees in many forests as well as important timber plants) and cycads, which display significant evolutionary features. In all, the volume assembles 509 species of ferns and fern allies and infraspecific taxa in 70 genera.

Book Description
This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.

Book Description
The product of twenty-five years of planning, research, and writing, Guide to the Vascular Plants of Tennessee is the most comprehensive, detailed, and up-to-date resource of its kind for the flora of the Volunteer State, home to nearly 2,900 documented taxa. Not since Augustin Gattinger’s 1901 Flora of Tennessee and a Philosophy of Botany has a work of this scope been attempted. The team of editors, authors, and contributors not only provide keys for identifying the major groups, families, genera, species, and lesser taxa known to be native or naturalized within the state—with supporting information about distribution, frequency of occurrence, conservation status, and more—but they also offer a plethora of descriptive information about the state’s physical environment and vegetation, along with a summary of its rich botanical history, dating back to the earliest Native American inhabitants. Other features of the book include a comprehensive glossary of botanical terms and an array of line drawings that illustrate the identifying characteristics of vascular plants, from leaf shape and surface features to floral morphology and fruit types. Finally, the book’s extensive keys are indexed by families, scientific names, and common names. The result is a user-friendly work that researchers, students, environmentalists, foresters, conservationists, and indeed anyone interested in Tennessee and its botanical legacy and resources will value for years to come.

Book Description
A much-needed field guide to the more than 120 species of ferns and fern allies occurring naturally in the state, Ferns of Alabama provides yet another window into Alabama's amazing biodiversity. Ferns of Alabama is a beautiful, full-color guidebook to the great variety of ferns and fern allies that populate Alabama woods, stream banks, prairies, glades, roadsides, and trails. Along with the ecologically similar but genetically unrelated horsetails, clubmosses, and quillworts, ferns are nonflowering vascular plants of ancient lineages that date back to the Devonian era. Although they are now known to be unrelated, all of these groups of plants were once thought to be part of a single division of the plant kingdom called pteridophytes because of their similarities in reproductive biology, and they are generally studied together. These plants occur in great variety and abundance in Alabama because of the temperate climate, the sufficient year-round moisture, and the multitude of available habitats, soils, and microclimates in the state. The individual species accounts by John W. Short and Daniel D. Spaulding contain a description of the plant and its habitat, range, history, conservation status, and common names. Color photographs by T. Wayne Barger, Alan Cressler, Sarah R. Johnston, L. J. Davenport, and John W. Short show the ferns in their native settings and black and white line drawings by Marion Montgomery, Sue Blackshear, and John W. Short highlight major features and peculiarities of form. Maps illustrate the county-bycounty distribution of the more than 120 species described. Taxonomic keys designed for the nonscientific user make it easy to pinpoint the identity of a subject being studied in the field, and a glossary explains necessary botanical terms. There is also an appendix by Alan Weakley addressing taxonomic change.

Book Description
This richly illustrated field guide serves as an introduction to the wildflowers and plant communities of the southern Appalachians and the rolling hills of the adjoining piedmont. Rather than organizing plants, including trees, shrubs, and herbaceous plants, by flower color or family characteristics, as is done in most guidebooks, botanist Tim Spira takes a holistic, ecological approach that enables the reader to identify and learn about plants in their natural communities. This approach, says Spira, better reflects the natural world, as plants, like other organisms, don't live in isolation; they coexist and interact in myriad ways. Full-color photo keys allow the reader to rapidly preview plants found within each of the 21 major plant communities described, and the illustrated species description for each of the 340 featured plants includes fascinating information about the ecology and natural history of each plant in its larger environment. With this new format, readers can see how the mountain and piedmont landscapes form a mosaic of plant communities that harbor particular groups of plants. The volume also includes a glossary, illustrations of plant structures, and descriptions of sites to visit. Whether you're a beginning naturalist or an expert botanist, this guidebook is a useful companion on field excursions and wildflower walks, as well as a valuable reference.

Book Description
The early 1990's marked an environmental watershed for our countly. Under two federal administrations significant environmental legislative, regulatOly and institutional changes took place which affected our Nation's wetland resources. Injust a few years, we have seen rapid evolution in the way in which we view wetlands with more emphasis on specific wetland types and the geographic provinces in which they occur. This Southern Appalachian Man and the Biosphere (SAMAB) conference on "Wetland Ecology, Management and Conservation" represents just one example of our desire to understand wetlands in non-coastal regions of the southern United States. The backdrop to this conference was one where the government, universities, and private sector have come together to create a broader and more sophisticated understanding of environmental stewardship for our water resources, especially wetlands. Although enforcement of environmental legislation by federal and state government agencies - limited by manpower shortages, budgetary constraints and undermined by weak enforcement - remains strong as measured by world standards; the realization that environmental degradation of wetlands is likely to get much worse necessitates a greater commitment and increased resource allocation for wetland protection and management. These contiIUled pressures on the wetland resource will create substantial opportunities for the application of environmentally-sound technologies and interdisciplinmy modeling teams to keep abreast of the factors influencing wetland integrity and function in the last half of the 1990's.
