Peter Savill - Böcker

For the first time, this book tells the Wytham story in a way that is accessible to both scientist and general reader alike. It provides a fascinating overview of what the Woods are like, their history, composition (both plant and animal), and how their wildlife has changed over time.This iconic location has been the subject of a series of continuous ecological research programmes dating back to the 1920s, a level of continuity of research effort that is extremely rare. Hence there is a strong emphasis on the significance of the scientific research that has been done there and how this has contributed to ecological thinking elsewhere.

British woodlands and forests are often located on sites and in regions that are marginal for agriculture; many are at high elevations and exposed, with short growing seasons. Wherever forests are located, site and climatic conditions must dictate species choice in forest management. This book provides a detailed guide to the biological suitability of different sites and soils for all important native trees and the most extensively used exotics. Apart from physical difficulties such as steepness and stoniness, forest soils also frequently have problems associated with them. They can be waterlogged or drought-prone, suffer from extremes of acidity or alkalinity, or have compacted layers. The book provides information on species' suitability for different purposes. It includes details of species' origin and introduction (where applicable), as well as their climatic and soil requirements and other silvicultural characteristics. Information about provenance, yield and timber is also provided. Fully updated throughout, this 3rd edition puts more emphasis on species suitable for changing climatic conditions, with accounts of several species that may become more prominent in British forests: including several silver firs, hickories, eucalypts, spruces, poplars and wingnuts. The book concludes with simple keys for identifying the trees most likely to be encountered in British forests. It is an essential resource for students, researchers and forestry professionals.
