B2N Weed Survey and Treatment

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.
