Protecting irrigation hose from wild boars

I live in the Samarian Highlands of Israel and am doing a reforestation project. I've got 600 meters of HDPE 25mm hose running down the mountain, then connecting to 16mm irrigation line with drippers.

We have a huge wild hog problem, and I'm thinking of ways to protect the hose. Burying it is impractical and the pigs dig it up anyway. What if I wrap the main line with barbed wire-would that work? Would it work for the irrigation line, or would that just puncture it?

Must admit I am surprised that you have this problem . Are The wild Boars targeting the pipe or is it just getting in the way of their normal foraging activity ? . Maybe having it  attached to a fence above the ground would help ?Pigs are very curious and will investigate any recent digging in the hope of finding food .

Boars will bite through irrigation pipe and roll in the mud produced (we are on limestone here, there is no standing or running water anywhere unless there's a rainstorm, and then at most for a day or two.)

Pipe is surface laid, not dug in.

I really don't want to build a 600m long fence.

How long is the line going to sit there? If it's a short time then two electric wires a say 10cm above it and slightly to each side might work. Otherwise how about raising it above boar height, it doesn't need to be a fence just posts every few meters with the pipe attached. It occurs to me if it is the water they want are they not going to dig out all your new trees as soon as you turn on the irrigation to them?
