Beskrivning

Measurements for Terrestrial Vegetation, 2nd Edition presents up-to-date methods for analyzing species frequency, plant cover, density and biomass data. Each method is presented in detail with a full discussion of its strengths and weaknesses from field applications through statistical characteristics of bias and use of the correct probability distribution to describe and analyze data. This practical book also covers the use of satellite imagery to obtain measurement data on cover, density and biomass. Field data collection includes current applications of statistical sampling and analysis designs that should be used to obtain and analyze these data.This new and thoroughly updated edition of a classic text will be essential reading for everyone involved in measuring and assessing vegetation and plant biomass, including researchers and practitioners in vegetation science, plant ecology, forestry, global change scientists and conservation scientists. Provides a comprehensive catalogue of sampling, surveying and measuring techniques in vegetation scienceUpdated to include new technologies and developments in the fieldNew coverage of prediction models for large areas, including satellite mapping and remote sensing techniquesIncludes up-to-date applications of statistical sampling and analysis designs used to obtain and analyse data Reviews the strengths and weaknesses of each technique, allowing an informed choice of alternative approachesClear diagrams to explain best-practice in methodology The companion website for this book can be found at www.wiley.com/go/bonham/measurements

Recensioner i media

“In summary, this book is excellent for describing the methods for measuring vegetative attributes (frequency, cover, density, and biomass) and the sampling design that will provide unbiased estimates for the attribute measured.” (Photogrammetric Engineering and Remote Sensing, 1 November 2014“Summing Up: Recommended. Upper-division undergraduates through professionals.” (Choice, 1 February 2014)
