Lines of tyres placed along true contours (Christo Spies)
The site of Geen Einde is typical of many areas in Lebowa: a large gully approximately 200 m wide and 10 m deep in places with semi-eroded pedestals remaining. Flood waters from the mountain meanders causes further gouging of the sides of the pedestals. Tributary gullies have formed in the highly erodible soil (high clay content) adjacent to the main gully. Signs of old contour bunds indicate that the land was cultivated in the past.
1. An earth silt dam was mechanically constructed across the main erosion gully.
2. Several gabion structures were constructed in the minor gullies.
3. Vetiver grass was planted in the silt to act as nursery material for future planting.
4. Old motor tyres were laid on a level contour above the minor gullies to harvest water.
5. Several species of indigenous trees were planted in the gullies and along the rows of tyres.
6. Two Agave species, local aloes and vetiver grass were planted along level contours.
7. Agave was planted along the edges of the gullies.
8. Shallow gullies were stabilised with old tyres and Agave.
9. Couch grass (Cynodon dactylon) was planted at a few places in the gullies and along the rows of tyres.
The main reason for these actions was to reduce the water velocity.

stabilised gullies can be used for production, in Lesotho such gullies are allocated
relatively cheap method using old tyres and ripper, the main expense is transporting the tyres
