Tony, it snowed last night, but I'll try to describe what it looks like in the summer. The goats make a shallow depression about 2'x3', starting about halfway down the hill. After a few years these areas were well fertilized, and the plant growth, mainly wild mustard, was abundant.
These aren't my goats, but they are allowed to overgraze this area every year. Actually, that may have helped.
I wouldn't tether them, I would let THEM decide where to put the depressions. Just fence off the area, put wethers on it until late fall, and then butcher. Start over in the spring for a few years. You've now got fertilized terraces.
Roberto, that's a good title. I wish I wasn't challenged by technology, it would be easier to edit.
That's interesting about Capricorn. I never knew that. We had no Capricorns in the family, so I never paid much attention.
More memories: I had to remember in which order the goats worked. The first area was the steepest slope at one side of their area. Then the steepest part of the middle of the area. Then it became all over, until I could go straight up without holding on to a fence! They also seemed to lessen the steepness overall.
