Reducing sediment and nutrient inputs to Torbay Inlet

This project site demonstrates methods of "best practice" aimed at reducing sediment and nutrient transport from a stream in Marbelup Water Reserve to Torbay Inlet.

The demonstration site is located on the corner of South Coast Highway and Corio Road in the Marbelup Water Reserve. The site works were carried out in January 2001, and included construction of a stock crossing and pool and riffle sequences in-stream.

The Torbay Catchment Group held several working days to carry out weed control at the site, ripping and mounding, fencing and planting of 2,500 fringing wetland species. Weed control is part of the ongoing maintenance required at the site.

Species planted at the site include:

   Rosa tea tree (Agonis linearifolia)
   White tea tree (Agonis parviceps)
   River cedar (Agonis juniperina)
   Lemon honey myrtle (Melaleuca densa)
   Melaleuca cuticularis, M. rhaphiophylla, M. preissiana
   Swamp bottlebrush (Beaufortia sparsa)
   Albany bottlebrush (Callistemon glauca)
   One sided bottlebrush (Calothamnus quadrifidus)
   Native willow (Callystachis lanceolatis)
   Knotted club rush (Isolepis nodosa)

The site has been ripped and mounded for planting; fencing to keep stock out is under way

Stream restoration project partners

Gary and Sunita Martin and family have allowed access and use of their land for the demonstration site. This commitment by the Martin family is much appreciated and has ensured the success of the project. The wetland's site works and plants were funded by the Natural Heritage Trust's Coast and Clean Seas Program, the Torbay Catchment Group and the Water and Rivers Commission. Torbay Catchment Group and Porongorup Green Corp volunteers have been instrumental in assisting with the site works and planting at the site.
