THIS Terrain is Unique...

Everything that starts has a cause = True
The Universe Started = True
Therefore The Universe has a cause!
I'm not ashamed of the gospel of Christ Which is, Jesus Died on the cross to pay for your crimes against God, and all you have to do to accept his payment is ask for forgiveness sincerely and trust in the death burial and resurrection of Jesus!

personally when it comes to trees you should use logs as the base and fences, end rods, chains and gates for the branches. With leaves make sure some are connected by just the corner and edge not the full face. For smaller trees use stone and diorite walls for the trunk
