One of three types of salinity in Western Australia caused where groundwater levels rise, bringing salt accumulated through ‘primary’ salinity process to the surface. This is caused by clearing of perennial vegetation in drier areas, ie. Areas that tend to accumulate salt in the soil profile and groundwater over time.

In Western Australia, rabbits are declared pests of agriculture under the Agriculture and Related Resources Protection Act 1976. This means landholders are required to control rabbits on their properties. Rabbits have a significant impact on the environment by grazing native plants, particularly on threatened plants and communities, and competing with native animals for food and habitat.

European red fox (Vulpes vulpes), were deliberately released into Victoria in the 1860s for fox-hunting. Unfortunately, is a highly adaptive and mobile predator. When the fox arrived in the south-west in the late 1920s it coincided with a steep decline in the numbers of smaller native mammals.

The Management Plan for the Commercial Harvest of Kangaroos in Western Australia 2019–2023 provides for the commercial harvest of red and western grey kangaroos in accordance with the principles of ecologically sustainable development.

Settlers introduced non-native bird species to help them feel more at home in this isolated corner of the vast Australian continent. These new species meant increased competition for resources with native species.

Rabbit haemorrhagic disease (RHD) is caused by the rabbit haemorrhagic disease virus (RHDV), a type of calicivirus which is fatal in non-immune rabbits. There are currently three pathogenic strains of this virus in wild rabbit populations in Australia.

1080 is a naturally occurring compound that is quickly broken down in the environment. Many native animals have developed a high degree of tolerance to 1080 while foxes (and domestic dogs and cats) are very sensitive to the poison. It is colourless, odourless, and tasteless and is therefore easily ingested by companion animals as well as native species.

Landholders that have growing concerns about declared weeds and feral animals in their community can form Recognised Biosecurity Groups (RBGs) under the Biosecurity and Agriculture Management Act 2007 (BAM Act).

Caused by the plant pathogen, Phytophthora cinnamomic, which kills susceptible plants, such as banksias, jarrah and grass trees, by attacking their root systems. More than 40% of the native plant species and half of the endangered ones in the South-West of Western Australia are susceptible. The fungus is spread through the movement of soil and mud, especially by vehicles and footwear.

Environmentally sensitive areas are declared by the Minister for Environment under s 51B of the Environmental Protection Act 1986 (EP Act). This fact sheet provides information on the declaration of environmental sensitive areas (ESAs), how to view the location of ESAs and how ESAs affect when a clearing permit is required.

Human activity causes the greatest spread of dieback. Road building and maintenance, mining, off-road driving, bushwalking and gardening can introduce and spread the pathogen through infected material. Dieback can then spread quickly downhill in water and slowly by growing from root to root.

Restoring biodiversity values on farmland through direct seeding and seedling plantings. Biodiversity provides stability of ecosystem function and therefore resilience to farming landscapes. A diversity of woody and herbaceous perennial plants adds stability to landscapes dominated by annual crops and pastures.

This booklet provides easy identification of common weeds and methods of control using common cultural, biological and herbicidal control techniques. The weeds are divided into four colour coded groups based on their lifeform and are grasses, herbs, vines and shrubs or trees.
