Sentinel plants, plants in exporting countries that are inspected at regular intervals for signs and symptoms of invertebrate pests and microbial pathogens, are a promising tool for detecting and identifying harmful organisms of woody plants prior to their introduction into importing countries. Monitoring of sentinel plants reveals crucial information for pest risk analyses and the development of mitigation measures. The establishment of sentinel plants requires the import and plantation of non-native plants, which may be affected by the laws, regulations and administrative procedures in the individual countries. To evaluate the feasibility of sentinel plants as a global approach, this study aimed to summarise regulations and administrative procedures that affect the establishment of sentinel plants using non-native plants in countries worldwide. Information about national regulations of import and planting of non-native plant species was collected through a questionnaire survey, conducted among national representatives to the International Plant Protection Convention. Over 40 countries responded. The results show that legislations and regulations should not be major obstacles for a global use of the sentinel plants approach. However, the few existing experiences show that it can be complicated in practice. Here we describe the current state of art of the procedures that should be adopted to establish sentinel plants and we propose a strategy to circumvent the shortcomings resulting from the lack of a specific regulation.

Bjørn ØklandAbstract
The populations sizes of Ips typographus in Norway have been monitored since the last big outbreak period in the 1970s. By now the monitoring programme includes about 500 pheromone-baited trap records for each of the last 40 years. Normally, Ips typographus has been the only species of major concern in northern bark beetle outbreaks, and trapping records have served as a warning when the over-wintering population sizes are large. In contrast to Central Europe, the regional trend in northwest is that rainy weather tend to slow down the bark beetle populations in many years, whereas stormfelling episodes of spruces, snowbreaks and warm and dry seasons in certain years favour Ips typographus and other bark beetle species. Recent observations indicate that other less aggressive bark beetle species may play a more important role during severe drought periods that follow rainful seasons with low production of Ips typographus. It is likely that an increased frequency of extreme weather events may have unexpected effects on what bark beetles become abundant during the course of the outbreaks. Furthermore, the warm years seem to be especially favourable for the Ips typographus at the northernmost latitudes. In addition, a new bark beetle species for Scandinavia, Ips amitinus, is expanding its range and may become a participant in future bark beetle outbreaks in this region.
