You're right, there is so much in the valley and in Southern Oregon, but not much in Central Oregon. There are some farms north of Bend that are permaculture based, but not much. I live in La Pine and am trying to plan with permaculture ideals, but it is hard due to the harsh climate (mostly temp fluctuations). Our soil is improving due to animal manure, composting, etc. I have some hugels in and starting more for water retention, and am in the process of several other projects. We did build a sunken greenhouse, this will be our first season with that. I am trying to make a food forest in the greenhouse. We'll see how it goes.
Given that OSU recently hosted that Permaculture course, would the OSU-Cascades campus (in Bend) offer anything of use for collaborative ventures in helping those in that region to get up and started? The following link shows some of the personnel there and you may tunnel backwards and forwards from that page to find something of interest or use: http://osucascades.edu/HERS/principal-investigators
