04 October 2023, AU: The third national survey of pests and weeds shows 85% land managers spent on average around $21,950 in 2022 on pest and weed species management.

Executive Director of ABARES Dr Jared Greenville said the results of the 2022 ABARES pest animal and weed management land manager survey demonstrates that the level of commitment required by land managers to control pests and weeds is increasing.

“Land managers reported that feral animals continue to cause considerable impacts on their properties in 2022,” Dr Greenville said.

“The survey showed 89% of land managers reported problems due to feral animals in 2022, up from 85% in 2019. Foxes, rabbits, rats and mice were the most common species reported as causing problems.

“There have also been reports of feral animals that are new to properties or have increased in numbers, such as feral pigs and deer, that are causing damage.

“About three-quarters of land managers continue to manage pest animals on their properties through various means.

“Ground shooting was the most common management activity, used by about 75% of land managers. Pesticide and/or insecticide use and ground baiting were also popular control measures, used by around 50% of land managers.”

There was also a small but meaningful increase in reports of weed related problems on properties since 2019. Around 60% of land managers reported problems with Weeds of National Significance in 2022, up from 58% in 2019.

“The most common weeds that were reported as being new to the property were Fireweed, Feathertop rhodes grass, Fleabane, African lovegrass, Thistles and Giant rats tail grass.

“More than 80% of land managers are actively managing weeds on their properties, with the application of herbicides remaining the most common weed management activity.”
