Available in PDF, EPUB and Kindle. Book excerpt: This book is an open access publication. Forest ecosystems in Central Europe are changing as a result of anthropogenic influences and changing climate conditions. As such, a large-scale monitoring programme was undertaken in order to understand the influence of site modification, deposition of air pollutants, and climate. This book presents the scientific findings of this study for Germany, including the major challenges with regard to the future preservation and management of forest ecosystems under environmental change. In addition, it addresses a number of central questions: what are the main factors affecting forest stands and soil integrity? How, and how rapidly, are forest ecosystems changing? How diverse are the changes across Germany? What will be the main risks in sustainable forest management in the future? And how can policy support the development and maintenance of adaptive and resilient forests that provide essential ecosystem services, today and in the future? Helping readers understand the importance of soils and related ecosystem processes for future sustainable forestry, and sharing essential findings on environmental change and related changes in forest status and dynamics, the book is a valuable resource for researchers and policymakers interested in science-based decisions.

Download or read book Wetland Indicators written by Ralph W. Tiner and published by CRC Press. This book was released on 2016-12-19 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with Wetland Indicators - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of Wetland Indicators. Practicing - and aspiring - wetland delineators alike will appreciate Wetland Indicators' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors. Features Color images throughout illustrate wetland indicators. Incorporates analysis and coverage of the latest Army Corps of Engineers delineation manual. Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation.

Book excerpt: Excerpt from Plant Indicators: The Relation of Plant Communities to Process and Practice The present book is intended to be a companion volume to "Plant Succession." The latter was planned to contain several chapters on the applications of ecology, but these were omitted on account of the lack of space. Chief among these was the consideration of succession as the primary basis for a system of indicator plants, and this has been made the theme of the present treatise. For the sake of clearness, it has been necessary to give a concise account of the climax communities of the region concerned. The original plan included a brief summary of the priseres and subseres of the various climaxes, but the limitations of space have precluded this. The same reason has made it desirable to deal with principles and examples in the three fields of practice, rather than to attempt a complete account of the host of climax and seral communities which serve as indicators. The general principles and specific indicators have been tested repeatedly during the field work of the past five years, and the treatment has profited from the fact that a special inquiry into indicator relations throughout the West was made during the season of 1918. It is believed that succession and indicators constitute the most essential and useful form into which the results of research can be put for practical use. They are the fundamental responses of plant and community to the conditions in control, and hence contain their judgment as to the fitness of the environment in which they grow or are to be grown. Such responses require translation into familiar terms, and for this purpose the quantitative analysis of habitats and responses by means of instruments and phytometers is indispensable. Moreover, habitat and response vary not only with the development of the community, but also in accordance with the phases of the climatic cycle. The importance of the latter can hardly be overestimated, and it seems certain that the climatic cycle must be accorded a unique position in all future research and practice. The indicator method will naturally have its greatest usefulness in new or partly settled regions. While the results given apply only to western North America, and to the western United States particularly, the principles and methods are of universal application. They should be of especial value on other continents where there is still a distinct frontier. Australia, South Africa, and South America should furnish fertile soil for indicator investigations and applications, while large portions of Asia and northern Africa should possess almost equal promise for this work. Even in Europe and in other thickly settled regions, indicator studies will have much value, and this will be true everywhere that natural or semi-natural vegetation is found. Indeed, it is probable that indicator methods in some form will come to be applied to all cultural vegetation with the advance of quantitative ecology and the disappearance of the artificial barrier between science and practice. The author is under especial obligation to Dr. H. L. Shantz for many helpful suggestions arising from the reading of the manuscript.

Available in PDF, EPUB and Kindle. Book excerpt: This original work makes unprecedented use of some of the most important research to date in plant ecology. It is a guide for assessing site quality, that is, the climate and soil of particular forest and non-forest ecosystems. Foresters have long been interested in using plants as indicators in predicting the growth performance of reforestation sites, but the data have not been readily available. Indicator Plants of Coastal British Columbia fully discusses how indicator plants are recognized and demonstrates how indicator plants can be used in site diagnosis. The book presents colour illustrations and descriptions of 419 selected vascular plants, bryophytes and lichens of coastal British Columbia. Indicators with similar values are grouped into indicator species groups which are used to evaluate site quality. These data are supplemented by information on geographic distribution, life-form, shade tolerance, and other ecological characteristics of the species. Three methods are given on how to use indicator plants for the purpose of site diagnosis. Indicator Plants of Coastal British Columbia summarizes original research in a format which both students and practitioners will find easy to use.
