Which solution?

Once decided the method, I set out to decide on the context,
I start considering hundreds of different plants in order to obtain that hedge effect that can reduce erosion. I search textbooks but soon I realize that hedges have to be composed by several kinds of plants,to obtain the beneficial effect of helping the farm economy, adaptability to all terrains and good palatability are conditions which I couldn't abide.The next problem to face is how to maintain the planting design of the hedges in time and how avoid that different species interfere with each other using as little space as possible
