Site work by South China Institute of Botany -- Mr. Xia Hanping et al.
| Typical highway cut slope, heavily eroding, devoid of all vegetation | Original highway site in 1996 before vetiver grass application. VTT was then applied to right hand cut slope (left hand cut left as control), and to unstable fill section |
| Right hand cut slope just planted with bare rooted vetiver grass | Fill slope planted to VGT plus Acacia mangium seedlings between vetiver rows |
| Right hand cut slope in 1997 showing VGT and hedge growth | Right hand cut slope in October 1999 Fully vegetated with some vetiver grass remaining |
| Right hand cut slope fully revegated - growth in October 1999 | Fill slope planted to VGT plus Acacia mangium seedlings between vetiver rows. Photo taken in 1998. Fill slope now fully revegated with excellent tree growth, and fully stabilized slope. |
| Left hand cut slope remains untreated and competely devoid of plants four years after right hand cut and fill slopes were stabilized with VGT and Acacia mangium | There are thousands of sites like these in south China. VGT can rehabilitate such sites at a fraction of the cost of more traditional methods. Furthermore VGT does it very quickly and efficiently. |
