I was reading on hugelkultur and it struck me that it could be very useful in a goat or other animals pen/pasture to build a large one and fence around it to plant trees or whatever your choice to allow access whenever .
just an idea to mull around.
And goats can be very useful when building a hugelkultur bed. Whenever I prune branches, I take them over to an area where I'm building a bed, and stack them up. The goats eat the leaves and deposit poop. Once a decent size has built up, I just cover the pile with soil, soak, and plant.
