Hi Frank,

Since the area is wooded, perhaps you might consider placing those large
beeches across the slope, on contour, braced by still standing trees.
Add to these whatever duff, litter, branches are about and in no time you'll
have a leaky kind of gabion/berm that on top of bioaccumulating humus will
serve to slow and spread the water, deal with gullying, and be a lot easier
than digging/ripping. This also puts into practice the PC principles of
using locally available biological resources, and doing the least work for
the gretaest effect....
