The international movement of pests and pathogens provided the impetus for the development of plant health regulations to minimise the risk of their introduction to countries outside their natural range. Before considering the organisational framework of plant health, this chapter presents a brief overview of the ecology of invasions, considering in turn the three key aspects of the invasion process: arrival, establishment, and spread. The principles and practice of plant health, from multilateral treaties to regional plant protection organisations, are then discussed under the topics of quarantine pests, pest risk analysis, certification and inspection, and quarantine treatments. A discussion of the problem of managing introduced pests includes the important topic of containment and eradication, with a case study from New Zealand of the eradication of the white-spotted tussock moth. With increasing globalisation of trade, the possibility of the emergence of new pests and pathogens is briefly considered, using Dutch elm disease as a case study.
