WESROC projects

This page contains information on the collaboration between the City of Subiaco and Western Suburbs Regional Organisation of Councils (WESROC) to implement regional water conservation and quality projects.

Western suburbs total water cycle project

Member local governments include Subiaco, Nedlands, Cottesloe, Claremont, Mosman Park, Peppermint Grove, with participation from Cambridge.

The Total Water Cycle Project monitored stormwater, groundwater and received environment water quality on a broad catchment basis. The project highlighted the following points for the western suburb local governments:

  • Stormwater was of suitable quality to harvest and use as a resource to boost groundwater supplies.
  • Education campaigns should target domestic fertiliser application as a key issue for stormwater and groundwater quality improvement.
  • Street sweeping is necessary to remove litter and leaf debris, despite having no noticeable effect on stormwater quality.
  • Gross pollutant traps remain important for their primary function, which is to remove larger pollutants (rubbish, litter) before reaching the receiving environment.

Greening plan for the western suburbs

A greening plan is a structured and systematic approach to managing, protecting, preserving and enhancing vegetation in parks, reserves, private land and road reserves. The City of Subiaco is renowned for its leafy streets, abundance of green open spaces and remnant mature trees, both native and of European heritage. The larger western suburbs area contains approximately 10 per cent bushland (675 hectares), with the largest portions contained in Bold Park and Swanbourne bushland. The region also borders Kings Park and Botanic Garden, which covers approximately 400 hectares and includes 267 hectares of significant remnant bushland. Although there are a high number of green spaces in the western suburbs, these spaces are fragmented, which threatens their ecological integrity.

The Western Regional Organisation of Councils (WESROC) identified the need to better manage its green spaces with a coordinated regional management strategy. In March 2002, Ecoscape Australia was engaged to develop the Western Suburbs Greening Plan. The plan is a strategic planning document that provides future direction for the comprising local governments to integrate the natural environment into the western suburbs. 

The plan outlines the existing wetland, bushland, riverine, coastal habitats and conservation reserves, along with vegetation density and Aboriginal and heritage sites. The plan identified and mapped greenways and regional linkage areas required to connect remnant vegetation, coastal and riverine habitats and wetlands in a cohesive network. The plan prioritises linkages based on those that connect with significant bushland areas, have good potential for greenway establishment or bushland regeneration.
