Pest plants

Pest plants (weeds) have a significant impact on agricultural production, costing Australia over $4 billion a year and over $19 million per year in the Limestone Coast. Pest plants also have a significant impact on the environment as they compete with native vegetation, much of which is food or homes for native animals.

The Limestone Coast Landscape Board aims to prevent the invasion of new weeds that threaten the region and to mitigate or eradicate many weeds currently present.

A pest management strategy for the region has been developed. This identifies priority weeds and their management actions.

There are four categories of weeds:

  1. Declared - the weed is a significant threat to agriculture, the natural environment and public health and safety.
  2. Priority - the weed poses a serious threat and is identified as being a priority within the region.
  3. Alert - the weed poses a serious threat but is not present in the region yet and has the potential to establish itself.
  4. Weeds of national significance (WONS) – weeds effecting on a national scale.
