Combat soil erosion

Wind and water are the main agents of soil erosion. 
Plants provide protective cover on the land and prevent soil erosion for the following reasons:
* plants slow down water as it flows over the land (runoff) and this allows much of the rain to soak into the ground;
* plant roots hold the soil in position and prevent it from being washed away;
* plants break the impact of a raindrop before it hits the soil, thus reducing its ability to erode;
* plants in wetlands and on the banks of rivers are of particular importance as they slow down the flow of the water and their roots bind the soil, thus preventing erosion.

We have a big open flat of grass, but by some places there are nothing because the sand is not good because of sun burn etc. So we worked on a project we harvested seekel bush  a lot of them and put it in the non developed areas. We have also put a lot of old grass there!
