Sort of posting this for Jamie and a couple others.
This is one of friends and clients that does permaculture gardening.
About every tree service dumps chips on them and whole brush. I personally have dropped a few or more trailer loads on them.
Also, when I prune their oak trees, they use the whole brush to make berms as well. The live oak down in that big pasture I just did, you can see it in the video, they started a berm just above it in the draw to help slow the water run off on it's way to the pond to help the tree out some. Not to forget, all that berm will be rotting and adding nutrients to the soil right there as well. Some interesting ideas.
