Trading off action against learning when searching for invasive pests

Strategically searching for invasive pests presents a formidable challenge. Limited funding means choosing between cursorily surveying many sites, or focussing intensively on fewer sites. Existing knowledge may help to target more likely sites, but this knowledge is not flawless and improving it also requires investment. This study examines how to best combine search coverage and […]
