Field guide for the identification of damage on woody sentinel plants.

Chapter 1 (Page no: 1)

Introduction.

This chapter introduces a guide for managers of sentinel plantings, botanical gardens or arboreta, as well as phytosanitary inspectors, who may have knowledge of common pests and diseases of woody plants, but may not know the likely cause of damage that they have not encountered before, for example, because it is a new type of harmful organism or a new type of damage on a known tree species. It is also possible that they are unable to distinguish between damage due to abiotic and biotic factors and between symptoms caused by pathogens and insects. The guide aims to provide a tentative identification of relatively broad groups of organisms and not definitive identification of the causal agents, which requires more in-depth knowledge than expected from most users. This field guide is the fruit of efforts of a large group of scientists from many countries, both entomologists and pathologists, brought together through COST Action Global Warning (https://www.ibles.pl/cost/).
