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.
