13100: Wetland construction in Serpentine National Park

    This project will rehabilitate a degraded area of land in the Serpentine National Park located on the Darling Scarp 50km southeast of Perth.

    A seasonally damp wetland will be created on the 0.4 hectare site to temporarily store surface water runoff generated by the surrounding National Park.

    Project activities include:

    • construction of an earth bund with a controlled overflow outlet
    • direct seeding with locally native seed
    • planting with locally native tube stock

    The wetland will hold and slow floodwaters that would normally be directed towards an urban area during major storm events. This will mitigate events that lead to major flooding in nearby Harris Street in 2010 which lead to the area being declared as a Natural Disaster Zone.

    Investment: $ 38 000
    Delivery organisation: Shire of Serpentine Jarrahdale
    Project duration: May 2014 - June 2015
    Location: Serpentine National Park (eastern end of Carex Walk)
