Wow, what a beautiful spot.
The hills are your friends and offer opportunities you can't get with flat pasture. These are a bit steep, but there is still a lot that can be done. Be careful, because swales on steep hillsides can be disastrous.
Unfortunately, the Regrarians US tour is over. It was an amazing opportunity to learn from Darren. Studying the Holistic information from Alan Savory will help, as does Joel Salatin. IMO, the holistic education from HMI would be very helpful. They have a lot of free resources on the site. This, complemented by the Regrarians Platform, could go a long way toward helping to get the land on a regenerative path. You can buy the first two chapters of the handbook, but the rest is still under development. They're amazingly rich in information.
Your situation looks really wonderful. Water in abundance and good growing conditions offer tons of opportunity. I'm a little jealous. :)
