CYRIL HART’s seminal work on woodland management and practices is back in this fourth edition, which covers a wealth of material including financial management, taxation, the integration of forestry and agriculture, silvicultural operations, grading of timber, valuations marketing, utilisation, non-wood benefits, saw-milling and nursery practice.

A modern classic that has been a trusted companion to forestry students and experts for decades, Practical Forestry is a must-have for anyone interested in working in, managing or preserving Britain’s lush and vital woodland areas.
