- Abstract
Hawkweeds (Hieracium spp.) are an eradication target in Victoria due to the detrimental impact they can have on the natural environment and agriculture. Surveillance planning is a necessary component of an eradication program, and here it is made difficult by the species' potential distribution over large and remote areas of the Victorian Alps. This paper describes recent surveillance planning for hawkweed, using a model to prioritise the highest risk areas for surveillance given the search hours available. The model uses variables relating to hawkweed seed dispersal and habitat suitability, as well as detectability and delimitation data to prioritise surveillance in areas at the highest risk of harbouring hawkweeds. The result is a rigorous and transparent three-year surveillance plan which can be updated and adjusted as the hawkweed program progresses.
