This book is a heavily-illustrated, internationally applicable, practical guide for the identification of likely causal agents of damage to trees and woody shrubs. It is intended for use in sentinel plantings – a new tool to identify pests in the country of origin, used to inform pest risk analysis and risk mitigation measures – where agents often may not be known and only damage visible.

– Aids the identification of the type of agent that may have caused observed damage, including pathogens, invertebrates and abiotic factors.
– Explains how to take and preserve samples and how to proceed to obtain a more definitive identification of pests.
– Includes a general damage chapter in addition to specific chapters on damage to leaves, buds and shoots, roots, trunk, and flowers, fruits and seeds.

This is an essential guide for plant health professionals, including inspectors for plant protection organizations, foresters and nursery managers, in addition to students of forest entomology and pathology.
