Pest Risk Evaluation and Pest management SYStems (PREPSYS)


PREPSYS logoThis multi partner project is focused on understanding how we can best prepare for, and manage if necessary, the risks and impacts of emerald ash borer (Agrilus planipennis) and bronze birch borer (Agrilus anxius). The project addresses key questions and gaps in our knowledge on the pests’ biology, control, dispersal and economic and environmental impacts.

The project will be delivered by an international partnership which includes organisations from the UK, Netherlands, Ireland, USA and Austria.

Research objectives

The main objective of the project is to provide evidence to underpin contingency planning, policy development and policy communication through assessing the entry, establishment, spread, impact and management of the emerald ash borer (EAB) and bronze birch borer (BBB). The emphasis is on reducing the likelihood of their entry and establishment but also in a worst case scenario, to provide evidence on how to cope should the pests succeed in establishing populations in Europe and the UK.
