Hello,
Rail road ties make a great frame for a back stop. So does old tires
Make a 1/2 hexagon shape with a couple of upright supports. Stack ties, pile dirt behind ties.
Or, do the same with old tires. Stack and fill with dirt.
On the dirt mounds plant some type of vining plants that require no tending ie. Kudzu etc. to combat erosion.
One thing to keep in mind is the possible emerging problems with EPA laws and non permitted home built ranges , such may arise if you ever plan on selling. etc.
Peace
