And to amend my original post on the subject: the owner did consult professionals, did use structural elements to stabilize the slope in addition to biological ones, and does consider safety first and foremost.
My point was to provide two biological solutions that had not been previously submitted. Vetiver turns out to be a champion. My gosh, it's a grass that has its own international association!
Is the assumption, then, that permaculture approaches could not possibly stablize a slope? That seems like faulty reasoning, given the number of variables involved for each unique situation and the stunning array of applications one could use..

Perhaps I can bring this to a close by saying that permaculture is applied to do what is appropriate, not to force an idea. "The problem is the solution" – the conditions and inputs will determine the possibilities. Herein lies the beauty of permaculture as a way of looking at things holistically, and without attachment to preconceived ideas or outcomes. But Owen's point is well taken – i.e. to have an understanding of what's going on with the mechanics of a slope, which involves soil, geology, and hydrology.
I trust that Kevin is very capable of making a good decision.

Slope failure, as I said in my previous email is NOT covered by insurance. Ask your agent. If your "experiential life" includes bankruptcy and a multi-million dollar lawsuit because your property fell onto your neighbor's house, maybe killing someone, then how are you going to feel? I've been an expert witness on cases of this kind. I really hate to ramp up the conflict here, but I just have got to tell you that you are living in a dream world if you think that it's no big deal to put public safety and the environment at risk because of some notion that it would be cool to transform a steep slope into a permaculture planting. Nice idea, but first you have to be sure you're not committing a massive and irretrievable error in judgment. I love permaculture and I love producing food, but I also love doing things right and staying out of trouble. Don't live in a dream world. Your actions have significant impacts on others. Find out what you're doing before you do it. Messing with land isn't a game. It's serious business, and safety is ALWAYS an overriding concern.

Yes! I believe vetiver grass is it. Thank you Vinay.
With all due respect to Owen, please don't shoot the messenger. I was trying to put Kevin in touch with someone who has a challenging slope and has done a lot of research and has had years of results and tinkering with the regime. Just passing along contacts and information here.
Yes, you can't beat professional advice and experience, but there are new things to be discovered if one wants to live an experiential life and has really good insurance, and where safety is not an overriding concern. Some people like the process of discovery as much as the goal. I'll leave it at that.

Hi Laura and Kevin,
It is Vetiver Grass. Doug Richardson, in Santa Barbara is doing a lot of work with vetiver grass. It is a grass that comes from the Indian subcontinent. It is very benign and has multiple uses as a Permaculture plant.

Kevin,
You might also want to talk to Mary Scaran, who is an acupuncturist in SB (she's in the phone book) and has a very steep slope running the entire length of her oak wooded and desert upland property that is permeated by a spring. She has planted lots of things to stabilize, including Persian mulberry trees (edible!) and some kind of grass -- can't remember which -- but a type of bunch grass that she selected for its very specific properties of soil stabilization. Mary practices permaculture, studies horticulture, and is a very fine acupuncturist.
Good luck.
--Laura

Thanks, John, and all others who have replied. �This is such a helpful �

per Dan's advice. �I need to pay good attention to the plants that �

Maybe I'll just grow food for the birds there.
I appreciate eveyone's help.
Thanks!
