While the cattle were being rotated through the pasture in the picture to the left, they were, for the most part, allowed to graze where they wanted. You can tell where they grazed by following the outline of the healthy yellow grass. As soon as the ground began to get too steep, or too rocky, the cattle would ignore it in their grazing pattern.
Upon closer inspection of these rocky areas, there is grass, but it is gray, matted and very unhealthy.
The results of this are in the picture below. Notice the grass is healthier and had much more growth than in the picture above. This is the result of grazing the cattle through this area one time. By utilizing "impossible to graze" slopes such as this you are improving biodiversity, hydrology, and stocking rates. At the very least, utilizing these areas will allow you to run at full capacity (as prescribed by conventional) methods while giving each grazing area once every two years.
