Weeds can threaten biodiversity, damage livestock and reduce the value of your land.

Under the Queensland Biosecurity Act 2014, everyone has a general obligation to manage declared weeds given they are considered a ‘biosecurity risk’.

Biodiverse Environmental staff have a strong knowledge of weed hygiene and the new Biosecurity Act in Queensland, along with excellent weed identification and horticultural skills.

Biodiverse Environmental can develop and implement a Weed Management Plan and carry out weed control using best practice eradication methods, whether it be for compliance or to improve the condition of the area.

Our Weed Management Plans include mapping of weed growth which indicates priority areas for management, as well as a complete weed species list and control techniques for each species. We make recommendations on control techniques that are most effective for eradicating the weeds while preserving the surrounding natural environment.

Our weed management services include:

  • Weed survey and assessment
  • Photo monitoring
  • Artificial Intelligence spot check aerial photo monitoring (DJI M300 Drone) 
  • Weed Management Plans
  • Weed control and maintenance
  • Weed hygiene inspections on vehicles, machinery and equipment


Below is a selection of weed planning and implementation projects

Project 1

Panorama Drive Upgrade Weed Survey and Control Works – 2023

This road duplication project required weed management services as part of the environmental management before construction of the 2km duplication of road.

Biodiverse Environmental was contracted to undertake a weed survey of all restricted and WoNS weeds within the road reserve and develop a report and mapping to guide the weed control works. 

The subsequent weed control works throughout the reserve concentrated primarily on Singapore Daisy (Sphagneticola trilobata) and 24 other invasive weed species using high and low volume spray equipment and other manual techniques to meet the weed treatment requirements for the upgrade. 

Project 2

Invasive Weed Management – 2022

Biodiverse Environmental carried out weed surveys for NF Corbett along the highway in Kilkivan to inform the client on the incursion of weeds listed as invasive species as per Biosecurity Act 2014 (QLD) for development or other purposes.

Invasive weeds were surveyed and mapped including both prohibited and restricted weeds as listed invasive plants by Biosecurity QLD.

Several restricted weeds and environmental weeds were record. Recommendations on weed control were given.

Project 3

B2N Weed Survey and Treatment – 2022

The Beerburrum to Nambour Rail Upgrade (B2N) project, involved upgrades of the rail line between Beerburrum and Nambour. The scope of the B2N project included rail duplication between Beerburrum and Landsborough and other infrastructure improvements.

Hall Contracting engaged Biodiverse Environmental to conduct a base line weed survey in 2021/ 2022 within the planned development corridor to determine the contemporary presence of weeds and restricted invasive plants. The information obtained through ground surveys were used to gauge weed control measures implemented throughout the construction and monitoring phases and as a comparison of weed presence over time.  

Following the weed survey, the weed control works were undertaken by Biodiverse Environmental’s experienced field crew. The weed control works consisted of traversing the entire rail footprint and treating all listed weeds using a variety of methods with backpack spraying and basal barking etc in accordance to the weed species and chemical safety data sheets. 

Outcomes achieved included a 90% reduction in listed weed species with the first treatment. This resulted in the beginning of the duplication project and met all the required biosecurity milestones for the client and government agencies. 

Project 4

Energen Weed Survey – 2021

Biodiverse Environmental acted as the third-party contractor to undertake a baseline weed survey for Enegen Field Solutions in 2021/2022 near a CSG pipeline in regional Qld. The work consisted of a weed survey of the entire site and a report submitted to the principal contractor. The survey was to be conducted before any civil works could occur. The weed survey report consisted of recommendations for the principal contractor to review along with recommendations for the management of any identified declared weeds in the report.
