Pest plants and weeds

Our local environment is rich and diverse, supporting natural systems, pastures, plantations and gardens. Environmental pests and weeds can destroy the natural diversity of the region. Some can aggravate health problems such as asthma. Others are poisonous to horses and cattle. Environmental weeds that have been considered a serious enough threat to warrant their control under legislation are termed “declared pest plants” (formerly termed “noxious plant” or “noxious weed”).

Legislation

Under the Biosecurity Act 2014, A landowner has a general biosecurity obligation to take reasonable steps to keep their land free of declared pests plants. Local authorities and government departments are required to control declared pest plants on land under their control.

Council Responsibilities

Council has implemented a Scenic Rim Biosecurity Plan and is committed to the control of declared pest plants within the region. The plan includes strategies and information for the local community.

Landowner and resident responsibilities

Landowners have a general biosecurity obligation to control declared pest plants on their land. Council staff can assist with identifying weeds found on your property and the supply of relevant fact sheets or booklets (Weeds of Southern Queensland).

Pests

Pest plants affect the lives of all Queenslanders. They degrade our natural resources, damage precious remnant vegetation, compromise biodiversity and interfere with human health and recreation.

The Biosecurity Act

The Biosecurity Act 2014 (the Act) commenced on 1 July 2016 and ensures a consistent, modern, risk-based and less prescriptive approach to biosecurity in Queensland.

The Act provides comprehensive biosecurity measures to safeguard our economy, agricultural and tourism industries, environment and way of life from:

  • Pests (e.g. wild dogs and weeds)
  • Diseases (e.g. foot-and-mouth disease)
  • Contaminants (e.g. lead on grazing land).

The Act replaced the many separate pieces of legislation previously used to manage biosecurity. Decisions made under the Act will depend on the likelihood and consequences of the risk. This means risks can be managed more appropriately.
