Goats for Reforestation

We have alder bush coming out of ears on the majority of our acerage. We want to clear this space out to make room for a future food forest. We are wondering what kind of goats would be best for this project and any other tips for newby goat owners. TIA!

The right goats would be large breeds, they will be able to get all the green leaves.
Get a book or two on goat care and keeping, you want at least 2 but 4 minimum is usually better. goats like company and they prefer other goats.
You will also need a goat house they can always get to should it start to rain, goats hate to get wet.
They will need some hay that is up off the ground too as a supplemental feed, lots of fresh, clean water to drink and things to climb on and crawl under. (they get bored and when that happens they tend to escape)

I wanted goats, and now I think I should mix with sheep as well.

Goats will do the job you want, obviously, but what have you planned for when you will plant your forest? Protect all trees from goats? Sell or eat the goats when you do not need them to eat/clean your place? The idea is simple: if you want to CLEAR the place, then you need (during a short time) MORE goats than what the land can maintain long term. If you get goats + sheep, you can keep sheep maybe better later on, as they are easier to keep, and tend to eat on the ground more than goats.
