Identification of new pest threats to Nordic coniferous forests

The aim of the project is to assess the pest risks associated with trade of ornamental plants to the health of the Norwegian, Swedish and Finnish coniferous forests in present and future climates. A database of pests that could threaten major coniferous forestry species will be prepared. The main pest species of importance and the commodities that can act as pathway of introduction will be identified. The climate suitability for the pests will be assessed, based on the current climate and based on the future warmer climate. The project will identify which of the main pest species of importance potentially may fulfil the criteria to become regulated pests within the European Union according to the new EU regulation 2016/2031.The project is done in a collaboration between the risk assessment research unit at Finnish Food Safety Authority, the unit for risk assessment at Swedish University of Agricultural Sciences (SLU) and The Norwegian Scientific Committee for Food and Environment (VKM).
