Abstract
(Englisch)
|
Woody plants for planting are recognised as one of the most important pathways for the introduction of forest pests and pathogens ('pests'). Many pest species can travel relatively unnoticed on their hosts and are introduced into the environment when planted outside, which increases the chance of establishment. This project aims to provide an overview of the trade in woody plants for planting and the phytosanitary practices in Europe. Databases of intercepted pests in European countries and of established alien forest insects were analysed. The results revealed that most intercepted pests on woody plants for planting are nematodes, followed by insects and fungi, and that most of the intercepted pests came from Asia and within the EU. By contrast, nematode establishments are comparatively rare, suggesting that inspections may focus too much on these organisms. Similarities between the identity of most frequently the intercepted and established forest insects provide indications of the most likely future invaders. A summary of the legislation regarding plant protection, in particular in relation with international trade, in Switzerland and the EU was expanded with a similar description for seven additional countries on five continents during the second year of the project. This was in part based on information gathered by a Chinese colleague and during a visit to the New Zealand Ministry of Primary Industries. An analysis of the trade in woody plants for planting is ongoing. The intra-European trade is being studied through a trade dataset of nurseries in one of Europe's main tree-producing regions. Analysis of the phytosanitary inspection practices in Switzerland and Europe was continued, in collaboration with European partners. These analyses will continue in the remaining year of the project.
