Uptake Update 2, 10.U.2 KI Demonstration Site

Covering about 4350 square km, Kangaroo Island is the third-largest offshore island in Australia (after Tasmania and Melville Island) and lies 15 km off the South Australian coast. Kangaroo Island is nationally important for biodiversity conservation, primary production and tourism, with nearly 50% of the native vegetation remaining. The Island is free of foxes and […]

South West Slopes Region Pest Management Strategy 2008-2011

Pest species are animals (including invertebrates) and plants that have negative environmental, economic and social impacts. In this document they are collectively referred to as pests. Pests are most commonly introduced species, though native species can become pests. In parks, pests may have impacts across the range of park values, including impacts on biodiversity, cultural […]

Snowy Mountains and Resorts Region Pest Management Strategy 2008-2011

The development of Regional Pest Management Strategies (RPMS) provides NPWS with a strategic approach to pest management across NSW. The Strategy developed for each region provides a tool to broadly identify pest distribution and their associated impacts across the park system. It details priorities for each Region, including actions listed in the PAS and TAPs […]

Far South Coast Region Pest Management Strategy 2007-2010

The development of Regional Pest Management Strategies (RPMS) provides NPWS with a strategic approach to pest management across NSW. The Strategy developed for each region provides a tool to broadly identify pest distribution and their associated impacts across the park system. It details priorities for each Region, including actions listed in the PAS and TAPs […]

Feral pig population structuring in the rangelands of eastern Australia: applications for designing adaptive management units

Feral pigs (Sus scrofa) are an invasive species in Australia. Their negative impact on conservation values has been demonstrated, and they are controlled in many areas in the rangelands of Australia. However, they are usually controlled over small, often ad hoc management units (MUs), and previous research has revealed that these MUs can be inadequate. […]

Vaccination of feral pigs (Sus scrofa) using iophenoxic acid as a simulated vaccine

Objectives: To develop an encapsulation method for delivery of vaccines to feral pigs, and quantify the effect of iophenoxic acid on captive feral pig blood iodine concentrations to assist in investigation of factors affecting vaccine uptake. Design and methods: Feral pigs were administered iophenoxic acid by oral gavage, and consumption was assessed for different encapsulation […]

Spatial and temporal patterns of feral pig diggings in rainforests of north Queensland

Feral pigs (Sus scrofa) are believed to have a severe negative impact on the ecological values of tropical rainforests in north Queensland, Australia. Most perceptions of the environmental impacts of feral pigs focus on their disturbance of the soil or surface material (diggings). Spatial and temporal patterns of feral pig diggings were identified in this […]

Ecological impacts of feral pig diggings in north Queensland rainforests

This two-year study examined the impacts of feral pig diggings on five ecological indicators: seedling survival, surface litter, subsurface plant biomass, earthworm biomass and soil moisture content. Twelve recovery exclosures were established in two habitats (characterised by wet and dry soil moisture) by fencing off areas of previous pig diggings. A total of 0.59 ha […]

Current and future threats from non-indigenous animal species in northern Australia: a spotlight on World Heritage Area Kakadu National Park

Non-indigenous animal species threaten biodiversity and ecosystem stability by damaging or transforming habitats, killing or out-competing native species and spreading disease. We use World Heritage Area Kakadu National Park, northern Australia, as a focal region to illustrate the current and potential threats posed by non-indigenous animal species to internationally and nationally recognised natural and cultural […]

Attractiveness of a novel omnivore bait, PIGOUT®, to feral pigs (Sus scrofa) and assessment of risks of bait uptake by non-target species

Following a bait-preference pilot study on captive feral pigs, a series of field studies assessed the attractiveness and target-specificity of a prototype manufactured feral pig bait (PIGOUT®). Two promising test baits and fresh meat reference baits were biomarked with iophenoxic acid and aerially distributed in 100-km2 blocks of land infested with feral pigs in western […]

Impact of feral pigs and other predators on macro-invertebrates, D’Urville Island.

The effect of feral pigs and weka on the abundance, composition and biomass of above- and below-ground macro-invertebrates was assessed every November over 3 years at two sites where pigs and weka, just pigs, and neither species were excluded on Attempt Hill, D’Urville Island. The large carnivorous snail Powelliphanta hochstetteri obscura increased both inside and […]

Simulating the spatial dynamics of foot and mouth disease outbreaks in feral pigs and livestock in Queensland, Australia, using a susceptible-infected-recovered cellular automata model

We describe an approach to modelling the spatio-temporal spread of foot and mouth disease through feral animal and unfenced livestock populations. We used a susceptible-infected-recovered model, implemented in a cellular automata framework, to assess the spread of FMD across two regions of Queensland, Australia. Following a sensitivity analysis on the infectious states, scenario analyses were […]

Carpal glands in feral pigs (Sus domesticus) in tropical lowland rainforest in north-east Queensland, Australia

Carpal glands (CG) of 105 feral pigs Sus domesticus, caught in the tropical lowland rainforest in northeast Queensland, Australia, between 1999 and 2004, were investigated to examine their function in chemical communication between animals, and their histology. Female feral pigs show significantly larger CG on the right leg than on the left leg while there […]

Using bioeconomic models to maximize benefits from vertebrate pest control: Lamb predation by feral pigs

The question “When should investment in pest control stop?” either explicitly or implicitly underpins decisions concerning pest control made at every level of enterprise or government, regardless of whether these decisions are tactical or strategic. Bioeconomic modeling provides a quantitative framework for considering the benefits and costs of alternative pest control strategies. In this case […]

Comparative Dose-response Relationships and Acceptability of Warfarin, Brodifacoum and Phosphorus to Feral Pigs

The oral toxicity and acceptability of warfarin, brodifacoum and phosphorus to captive feral pigs were assessed in dose-response studies and preference tests. The LD50 and LD90 (with 95% fiducial limits) for these toxins ingested in wheat bait were: warfarin (two consecutive doses separated by 24 h) LD50 2.9 mg kg-1 (l.8-5.2), LD90 6.1 mg kg-1 […]

Disease surveillance in wildlife with emphasis on detecting foot and mouth disease in feral pigs

Surveillance strategies for detecting disease in wildlife are reviewed. Opportunistic and structured surveillance schemes are examined, and the detection of foot and mouth disease (FMD) in feral pigs (Sus scrofa) in Australia discussed in more detail. The probability of detecting an individual case of FMD in feral pigs in Australia with the current opportunistic surveillance […]

The influence of pasture distribution, temperature and sex on home-range size of feral pigs in a semi-arid environment

In this study the home-range sizes of feral pigs (Sus scrofa) at Nocoleche Nature Reserve, semi-arid New South Wales were measured by radio-telemetry over the course of a drought. The abundance of food was indexed simultaneously by the amount of pasture in the four most common habitats at Nocoleche (shrubland, woodland, riverine woodland, and ephemeral […]
