Goats are really great foragers but sheep are better grazers- that is, they prefer pasture. A problem we might encounter with goats is plant toxicity. Goats cannot eat bracken fern and milkweed. Both occur along our ROW. Wilted cherry tree leaves and branches are also toxic. There are ways around this, however.
We are probably getting some goats either this year or next, so we should be able to test this. Meanwhile, seeding along the ROW with a wildflower mix could not only help us manage the ROW more easily, it could also provide a point of interest for visitors.
