Vegetation Cylinders are netlon tubes usually filled with an organic material e.g. wood chips. The cylinders are used to retain soil in applications where the existing material (slope) is too hard for normal successful vegetation establishment (roots have difficulty in penetrating hard surface).
The cylinders are filled and then fixed to the slope horizontally (with wooden/steel stakes & wire) forming rows roughly 1 (one) meter apart.
Topsoil is then placed between the cylinders, The slope can then be scarified and hydroseeded.
The Disadvantages of Vegetation cylinders are:
• Relies heavily on the succession of grasses to colonise affected areas for a
long term vegetative solution.
• UV Degradable and over time may leave bare areas where erosion can form.
• Veld fires can cause extensive damage to Netlon tubes.
