Baseline Weed Survey

E2M was commissioned by APA to conduct targeted field surveys of all APA owned and operated transmission pipelines throughout Queensland.

The objective of the scope was to ensure that APA’s operation and maintenance activities align with the requirements of the Queensland Biosecurity Act 2014, along with other legislative requirements.

Challenges

The project required E2M to perform targeted weed surveys across large scale areas and challenging landscapes.

 

Innovation

E2M identified several efficiencies that were achieved using innovative data capture techniques developed specifically for biosecurity surveys. Within the nominated survey areas, two assessment zones were defined. This incorporated the ‘On disturbance’ easement and ‘Off disturbance’ 20 metre wide Visual Inspection Buffer (VIB) adjacent to the easement. The value addition of the ‘off disturbance’ VIB zones allowed APA to compare density and distribution information of weed populations within and adjacent to the easement. This assisted with determining where biosecurity management actions are required to be prioritised.

Outcomes

Pre-survey planning, spatial modelling and an efficient data capture method afforded significant cost savings for our client. E2M successfully prioritised those assets with a higher risk of declared weed species and essentially closed significant information gaps on priority weeds for management. The surveys have provided APA with specific information on priority weeds for management.
