An invasive species is an organism that causes ecological or economic harm in a place where it does not occur naturally.

Whatever their means of arrival, invasive species can have a damaging impact on agriculture, the natural environment and our lifestyle.

Keeping invasive species out of WA, or quickly responding to new incursions, is the highest priority for the State Government. It offers the best return on investment.

For invasive species already in WA, the Department of Agriculture and Regional Development has prioritised its response to focus on high-priority animal and plant species.

The Department will consider additional species - not on the high priority listing - only if there is demonstrable commitment from other stakeholders to take the lead in their control. These stakeholders can include other government departments and authorities (e.g. Department of Biodiversity, Conservation and Attractions, local government) and community groups.

Many introduced animals have established large populations across Australia, becoming widespread pests. These pests can significantly affect agricultural productivity and the environment.

Using the term established and/or widespread pests can get on some people's nerves because they object to the inference that they cannot be eradicated.

The PHBG believes that established pests can be removed from an area and kept under control with diligent follow-up. Established pests can also be prevented from taking hold in 'clean' areas with rigorous surveillance and quick remedial action.

However, the absolute eradication of established pests across large and complex landscapes is unlikely. If the Peel Harvey was a small island or had a big barrier fence around it, and we could patrol the borders, there would be a better chance for eradication.

Coordination amongst landholders, community, industry and government is necessary to manage pests at a landscape scale.

The term community coordinated approach is newly coined.

Essentially, it is decision-making that is undertaken by, with, or on behalf of a community, by a group of community stakeholders.

The community coordinated approach has raised the shackles of some landholders as they feel it is another sign that the State Government is backing away from the management of established and declared pests.

Indeed, a clearer understanding needs to be struck between what is best achieved by the community and what is within the scope of government (especially with regards to laws, and the enforcement of those laws).

Recognised Biosecurity Groups (RGBs) are incorporated associations meaning they can perform lawful acts that are necessary or convenient for carrying out their objects and purposes.

RBGs are endorsed by the State Government through the provisions of the Biosecurity and Agriculture Management Act 2007. They do not have any statutory powers.

Ultimately, a well governed and functioning RBG will take the following steps to self-reliance:

• it will assume responsibility

• it will be well informed

• it will know where it is going

• it will make its own decisions.

The work undertaken by RBGs is intended to add value to pest control undertaken by individual landholders and is not intended to replace individual responsibilities.

The Declared Pest Rate is a mechanism that provides Recognised Biosecurity Groups with ongoing funds to carry out their work on declared pest control. Funds raised by the rates are matched by the State Government under the Biosecurity and Agriculture Management Act 2007.

Activities funded by a declared pest rate can include;

• promoting best practice pest management to landholders in their area, and developing and working with networks that encourage community involvement in biosecurity

• preparing annual work programs, including operational and budget planning

• carrying out operations or engaging contractors to manage declared pests

• the management of association affairs including paid support such as executive officers.
