Erosion  

  • Rainforest soil is generally very low in nutrients, and erosion of cultivated soil will carry nutrients from fertilisers into the waterways, causing significant localised damage.

  • Many streams here, including Cooper Creek, have endemic fauna and flora and the impacts are not well understood.

  • Generally speaking, the impact of erosion is highest close to waterways and on slopes, especially where the surrounding land is cultivated.

  • If you have cultivated land, try to minimise use of fertilisers and address any eroded areas as quickly as possible, especially along drainage lines.

  • Fill erosion heads with native brush at the end of the wet season.  This will help stabilise the soil and also catch seeds to aid natural regeneration.

  • Plant fast growing natives with extensive root systems to stabilise the soil – DSC does have substantial experience in revegetation project as does a few not for profit organisations.

  • The faster the water runs, the more power and velocity  it will have.  Try to slow overland flow using sandbags and well-designed drainage in problem areas.

Driveways are a constant work in progress – walk along yours during a rain event to see how the water flows.  You may be surprised to find you ‘flat’ driveway becomes a shallow river.  This is a nut that hasn’t been cracked, though there are certainly well built and poorly built driveways – check our Driveways section for more information.
