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 handbook 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.
Information is provided on species' suitability for different purposes. The book 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 new edition in eludes numerous drawings of leaves and fruits to aid identification. The book concludes with simple keys for identifying the trees most likely to be encountered in British forests. It is a useful resource for students, researchers and forestry professionals.
