[Scpg] steep permaculture slope ideas?

[Kevin Gleason]

Hi all,

I was wondering if anyone has good advice for creating a garden on a  
VERY steep slope (more than 45 degrees.)  I'd love some feedback on  
alternative terracing methods, whether this is too steep for small  
swales, good soil-holding, drought-tolerant  ground covers and other  
plants that would be useful and other ideas.  I remember hearing Brock  
Dolman talking about making retaining walls with burlap tubes filled  
with soil and a little cement.  Anybody tried it?

Thanks for your help!
Kevin
