If I were a gamemaker this would be my map The second you reach the mountains mutts are released (different depending on which mountain you go to) those roses on the island are poisonis if your exposed to them for an hour your dead but there smell attracts the tributes so they want to stay there and second to last the berry bushes are stacked force-field high and the berry's are poisonis to. lastly the forests trees have tracker jackers in them.
