Rabbit Fencing To Protect Crops And Pastures, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

This factsheet outlines the use of fencing to protect crops and pasture from rabbits.

Rabbits cause an estimated loss of $217 million each year to Australian agricultural production and cause significant environmental damage. In Western Australia (WA), areas of native vegetation, particularly on sandy ridges that would otherwise be subject to wind erosion, have been retained on farms. Bush remnants are a major refuge habitat for rabbits, which can cause considerable damage to nearby pastures and crops. A measure of rabbit control can be achieved by poisoning around bush remnants in late summer or autumn, prior to seeding. To be …

European Wasp: Declared Pest, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

The European wasp is one of the worst wasps in the world — harmful to people, outdoor lifestyles, and horticultural and agricultural industries. Early detection of wasp activity is critical to prevent the wasp establishing in Western Australia (WA). This is achieved via collaboration between residents, businesses, industry, and government.

European Wasp Information For Local Government, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

The department’s European wasp surveillance and eradication program is a yearly campaign, aimed at detecting the presence of this destructive pest as early as possible so that nests can be found and eradicated.

The continued success of European wasp surveillance and eradication program relies on surveillance in metropolitan Perth and regional areas, strong community awareness, and participation between residents, business owners, community groups, industry, and government.

Evaluation Of Dual Purpose Canola And Cereals Grazed With Cattle, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

The Department of Primary Industries and Regional Development conducted research to investigate and demonstrate the importance of dual-purpose crops (canola, wheat and barley) to improve the feed availability for cattle (in late autumn to early winter) in mixed farming systems of the high rainfall environment of Western Australia (WA).

The grain yield of a wide range of canola and cereal varieties sown in mid-April were unaffected by the grazing of cattle at a stocking rate of 20 to 22 dry sheep equivalent (DSE) per hectare (ha) for up to 4 weeks at Esperance in 2011.

The grazed crops yielded the …

Yellow Crazy Ant, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Yellow crazy ants (Anoplolepis gracilipes) are believed to be native to west Africa or Asia. They are not present in Western Australia (WA) and are prohibited.

Yellow crazy ants were first observed in Australia in the early 1900’s on the Cocos-Keeling Islands and Christmas Island, where they have now caused a massive decline in the population of iconic red crabs. More recently, they have been recorded in Queensland, the Northern Territory (NT), and New South Wales (NSW).

Rabbit Control: Warren And Harbourage Destruction, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

If correctly and appropriately undertaken, the destruction of rabbit warrens, or modification of the habitat so it becomes less favourable to rabbits, can be an important and effective part of reducing the impacts of rabbits.

Destruction of warrens can improve the overall effectiveness of rabbit control programs, even though many rabbits live and shelter above-ground under bushes, and in scrub). If undertaken properly, the ripping of rabbit warrens can often provide a relatively permanent and long-term benefit. Similarly, removing or modifying other forms of rabbit-harbourage (for example, removing rock piles) can help, particularly in semi-urban areas or on smallholdings.

Rabbit Control In Urban And Semi-Urban Areas, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

This factsheet provides information on control options for rabbits in urban and semi-urban areas in Western Australia (WA).

Rabbits cause considerable losses to agricultural and horticultural industries. They can cause serious environmental problems, such as soil erosion and degradation of native vegetation. Rabbits also compete with native fauna for food and habitat.

Rabbits may be a problem or a nuisance in urban environments where they can damage lawns and gardens, buildings, garages, and sheds. Rabbits can also damage golf courses, sports grounds, and parkland reserves.

The options for control of rabbits in urban areas are more limited than in rural …

Water Lettuce And Its Control, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Water lettuce (Pistia stratiotes) is a declared pest in Western Australia (WA). This factsheet describes the nature of the plant with links to requirements landowners/occupiers must adhere to and pest control methods.

Argentine Ants, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Argentine ants (Linepithema humile) are small, brown, and notorious worldwide for being one of the most difficult and costly ants to control, as it can involve ongoing and repetitive use of residual, contact insecticides. The ants are established in Western Australia (WA).

Electric Ant (Little Fire Ant), Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

The electric ant (Wasmannia auropunctata), also known as little fire ant, is a tiny, gold-brown coloured ant, and one of the world's most invasive pests. Electric ants prey on and compete with other insects and can displace large numbers of native animals, ants, and other insects.

They affect human health and lifestyle, can inflict painful stings on humans and wild and domestic animals, can blind pets, damage the environment, and have the potential to severely affect agricultural industries.

The electric ant is native to Central and South America and was first detected in Australia in 2006 in Queensland, where there …

Altitude-Driven Variations In Chrysophycean Stomatocyst Assemblages: Implications For Climate Reconstructions In The Three Parallel Rivers Of Yunnan Protected Area, China, Yanling Li, Qi Liu, Yangdong Pan, Wanting Pang

Environmental Science and Management Faculty Publications and Presentations

The Three Parallel Rivers of Yunnan Protected Area (TPRYPA) is in the core area of the Hengduan Mountains, characterized by paralleling alternately high mountains and canyons that led to significant vertical temperature variation. Developing a climate transfer function for this region is crucial for both biodiversity protection and enhancing our understanding of feedback mechanisms between low-latitude and high-altitude areas in the context of global climate change. We investigated the chrysophycean stomatocyst assemblages from surface sediments of 46 high mountain lakes (altitude: 3244 to 5043 m) in the TPRYPA to assess the suitability of cysts in prediction of climate variability in …

Carbon Restoration Potential On Global Land Under Water Resource Constraints, Shouzhang Peng, César Terrer, Benjamin Smith, Philippe Ciais, Qinggong Han, Jialan Nan, Joshua B. Fisher, Liang Chen, Lei Deng, Kailiang Yu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Ecosystem restoration is a critical nature-based solution to mitigate climate change. However, the carbon sequestration potential of restoration, defined as the maximum achievable carbon storage, has likely been overestimated because previous studies have not adequately accounted for the competition between ecosystem water demands for maximizing carbon sequestration and human water needs. Here we used a comprehensive process-based model combined with extensive land-use data and evaporation recycling accounting for land–atmosphere feedback to estimate the water requirements associated with ecosystem restoration. We found that achieving the carbon sequestration potential of restoration would significantly reduce global water availability per capita by 26%, posing …
