The acceptability of four different bait station designs (drum, slab, tyre, corrugated iron) to rabbits was tested in the field using unpoisoned oat bait. The drum (200 L, cut longitudinally) and the raised concrete slab (60 × 60 cm) designs were the most acceptable to rabbits. The raised tyre design was unacceptable, and this was supported by later field efficacy trials that compared the drum and tyre designs using 1080 One-shot oats. The efficacy of three of these designs (drum, slab, tyre) against 'urban' rabbits was assessed more fully using pindone oat bait. The tyre stations were again found to have little impact on rabbit numbers. With the exception of one drum site where pindone bait stations were totally ineffective, the proportional reductions in rabbit numbers for the remaining sites were similar between the drum (69%, n = 3) and slab (70%, n = 5) designs. However, the slab design provided much easier access to bait by non-target species (particularly birds), and we therefore recommend that the drum design would be the best bait station for controlling rabbits. The overall proportional reduction in rabbit numbers achieved with pindone bait stations was 48% (range 0–80%, n = 13), which is less than that usually achieved during broadacre control programs with pindone (60–90+%). In addition, these kills took 30–60 days to achieve, and as rabbit damage still occurred over this period, the use of pindone bait stations did not always result in damage mitigation or, ultimately, an economic benefit. Some potential problems associated with the use of pindone bait stations, such as the possibility of the development of 'resistance' to pindone bait and the risk to non-target species, are also discussed. The combined use of track counts and a 'digs' index proved a reliable indicator of changes in rabbit abundance.
Introduced Marine Pests (IMP, = non-indigenous marine species) prevention, early detection and risk-based management strategies have become the priority for biosecurity operations worldwide, in recognition of the fact that, once established, the effective management of marine pests can rapidly become cost prohibitive or impractical. In Western Australia (WA), biosecurity management is guided by the " Western Australian Prevention List for Introduced Marine Pests " which is a policy tool that details species or genera as being of high risk to the region. This list forms the basis of management efforts to prevent introduction of these species, monitoring efforts to detect them at an early stage, and rapid response should they be detected. It is therefore essential that the species listed can be rapid and confidently identified and discriminated from native species by a range of government and industry stakeholders. Recognising that identification of these species requires very specialist expertise which may be in short supply and not readily accessible in a regulatory environment, and the fact that much publicly available data is not verifiable or suitable for regulatory enforcement, the WA government commissioned the current project to collate a reference collection of these marine pest specimens. In this work, we thus established collaboration with researchers worldwide in order to source representative specimens of the species listed. Our main objective was to build a reference collection of taxonomically vouchered specimens and subsequently to generate species-specific DNA barcodes suited to supporting their future identification. To date, we were able to obtain specimens of 75 species (representative of all but four of the pests listed) which have been identified by experts and placed with the WA Government Department of Fisheries and, where possible, in accessible museums and institutions in Australasia. The reference collection supports the fast and reliable taxonomic and molecular identification of marine pests in WA and constitutes a valuable resource for training of stakeholders with interest in IMP recognition in Australia. The reference collection is also useful in supporting the development of a variety of DNA-based detection strategies such as real-time PCR and metabarcoding of complex environmental samples (e.g. biofouling communities). The Prevention List is under regular review to ensure its continued relevance and that it remains evidence and risk-based. Similarly, its associated reference collection also remains to some extent a work in progress. In recognition of this fact, this report seeks to provide details of this continually evolving information repository publicly available to the biosecurity management community worldwide
