R Scott has a good point about working collaboratively with the farmer. We bought our 10-acre place and found that the previous owner had an agreement with a neighbor who could come over and cut and bale the hay in return for keeping the other areas of the property brush cut and looking nice. The neighbor has goats for some of the hay and sells the rest. Since we bought the property in Dec. the guy baling the hay already had plans for the hay that following summer. It would have been a crappy thing in my opinion to not keep the former arrangement since it was mid year like that. Besides, it helped me make good neighbors with the guy who cuts the hay ... he's since helped me a lot with his big
tractor and front-end loader with a few things and he was more than happy to help because he knows he was getting the hay from me. As Wendell Berry put it, we must be good neighbors on this planet.
What this did was allow me to focus on getting my
polyculture orchards going and start my earthworks in swale building and planning where the
pond will be. I'm not an experienced
permaculture practitioner, but the one thing that I would recommend is to spend more time in observation than you think you really need. Become so intimate with your land that you know when it hiccoughs or burps. Observe, observe, observe. From my one-year of
experience in the start of coverting 10 acres of pasture into a prennially producing food forest, I have found that observation is way under rated and I could have stood for a bit more time in observation before taking my first action. Upon hindsight, I would have been better off simply spending time out on the land and making careful observation of everything:
water flow through the landscape (including my neighbors'), wind tendancies,
solar angles and shadows, wildlife patterns, etc. I also have learned not to trust my eyes when trying to understand the topography. I now use a water level (two tall stakes and a 20-foot clear tube of water attached between them) to help me find actual contour lines. Maybe others have a better eye than I do, but now my contour lines are determined within 1/2-inch tolerance.
So, put shortly, OBSERVE!!!
If I had 12-13 acres of woods as you have, I'd seriously consider running hogs.
