The presence, distribution or abundance of many invasive alien plants is positively correlated with roads, so roads need to be taken into consideration when planning a survey in a poorly studied area. During the two field surveys organized in the framework of the 2nd Workshop on Invasive Plants in the Mediterranean Type Regions of the World, 81 alien species were observed in the investigated area, i.e. 70 neophytes and 11 archeophytes (including 9 doubtful species), with 54 new records for the DAISIE inventory. Three of these species, Acalypha australis, Microstegium vimineum and Polygonum perfoliatum, were recorded near a tea factory, and the import of material for tea processing is expected to have been their pathway of introduction. The results of this survey in the region of Trabzon in North-East Turkey show that roadside surveys are a useful tool for early detection efforts, in compiling and updating national or regional inventories (especially with time and budget constraints). This survey, being organized in the framework of an international workshop, enabled knowledge to be shared between experts in the field, and training of students and researchers. These survey methods could be adapted, improved, and used elsewhere by others seeking to use early detection as part of their overall weed strategy or to gather baseline data on invasive alien plants in a poorly studied area. © 2011 The Authors.

International, regional and national standards for plant health pest risk assessment and examples of their use from countries around the globe were examined together with similar documents from related fields such as animal health, nature conservation and genetically modified organism (GMO) assessment to determine how the consistency of assessing risk, or components of risk, within and between assessments is addressed. A range of approaches was identified that could be adopted and adapted for use in a revised decision support scheme for quarantine pests by the European and Mediterranean Plant Protection Organization (EPPO) to aid consistency. No single scheme contained a mechanism to ensure or guarantee consistency and no single scheme contained all of the approaches identified to maximize consistency. If the approach of using a five division scale to describe individual components that contribute to evaluating the overall pest risk is to be maintained in the EPPO scheme, then the primary needs required in the EPPO scheme to enhance consistency are (i) the provision of examples that describe divisions within the scales, or alternative but equivalent descriptors that allow assessors to distinguish between divisions, and (ii) a mechanism to combine risk elements in a consistent and transparent way. Features that would help inexperienced assessors include a clear structure, clear rating guidance, questions posed unambiguously, provision of standardized answers and an easily applicable method to interpret and summarize risk ratings. Beyond improvements to the EPPO scheme, assessors using the scheme will need training. Providing links to information and suggesting data sources that would help assessors answer questions would also be helpful (this is being addressed in Work Package 1 of PRATIQUE). © 2010 The Authors Journal compilation © 2010 OEPP/EPPO.
