Threatened Flora Monitoring

Two surveys, conditioned under Nature Conservation Act 1992 clearing permits, were required to quantify the abundance of threatened flora within disturbed areas associated with Coal Seam Gas (CSG) infrastructure.

Threatened flora species targeted included:

  • Rutidosis lanata (Red-soil woolly wrinklewort)
  • Eleocharis blakeana (Blake’s rush)
  • Acacia pedleyi (Pedley’s wattle)
  • Acacia tenuinervis (Scrub wattle); and
  • Acacia wardellii (Wardell’s wattle).

Challenges

E2M was tasked with efficiently determining the location and abundance of threatened flora populations using multiple sources of historic data collected by various companies. This required a desktop assessment and critical analysis of multiple sets of supplied data to determine the location and abundance of threatened flora to facilitate survey scoping.

 

Innovation

E2M was able to quickly and accurately analyse large quantities of data, in varying formats to determine locations of threatened flora within the Australia Pacific LNG Project area. This process optimised field surveys and therefore resulted in direct cost savings for our client.

Outcomes

E2M was able to consolidate the supplied data into a comprehensive dataset of threatened flora within the Australia Pacific LNG Project area. This exercise allowed E2M to plan and execute efficient field surveys. Two surveys were conducted by E2M to optimise detection of seasonal species. The results of the threatened flora surveys identified all of the species reoccurring within the Australia Pacific LNG Project area. Data analysis and reporting was able to clearly describe the current populations and compare those to previous monitoring period results provided by the client. The report was utilised as a compliance document to report against monitoring requirements of permits for taking protected plants.
