“Field guide for the identification of damage on woody sentinel plants” has now been published online. It is the most recent outcome of the Cost Action FP1401 “A global network of nurseries as early warning system against alien tree pests (Global Warning)”.
This field guide is intended as an aid for managers of sentinel plantings, botanical gardens or arboreta, as well as phytosanitary inspectors. It aims to provide a tentative identification of relatively broad groups of pests and diseases and not definitive identification of the causal agents. It contains chapters that explain how to use the guide, keys (for different organs of conifer and broadleaf species) to guide the user to the relevant sections of the book, based on the questions entomologists and pathologists ask themselves when looking at a damaged or diseased tree in a fashion similar to how a doctor interrogates a patient to arrive at a diagnosis. The largest part of the book is devoted to the description and illustration of damage types and typical causes of the observed damage. The last chapters provide instructions for taking and preserving samples for further identification by experts.
