Best ways to add trees to pasture

[Austin Unruh]

Hello folks!

I'm looking for the best ways to get trees into active pastures, while having livestock grazing. I haven't yet found an option that is cheap, effective, and low-maintenance enough to really qualify for large-scale plantings. 

I'm also interested in what folks have tried, and what has worked/not worked. 

Here are the current best options I see:

Fool-proof but expensive: Arbor Shield

Great for sheep farms: Tree Tubes. Plantra systems would be my go-to

For rotational grazers: Short shelters (something like this) and portable electric fence. Can inexpensively protect a whole row of trees. Drawback is that you have to commit your paddocks to just that size to protect your tree lines.

What have you found to work or not?

For goats, I plant 3 cedar posts each with 6 insulators (or 6 doubles to make the right angles) equilaterally around individual trees, and run 6 rows of electric wire. If the tree is not in my fence line, I use cheap extension cords and wire the AC plug ends from a live fence to my tree. The extension cords get buried in the grass, but still may not hold up to cattle.
