Tardyviking, glad I could be of some assistance.
The pine is the same species although the Digger Pine name was directed as a bit of a slur toward the native Americans here (by the White Eyes) who used to eat the seeds as well as make necklaces from them and other things. Bull Pine is another name for them. Also Gray Pine.
http://en.wikipedia.org/wiki/Gray_Pine Southeast farmer, the fence is about 5 or so feet high but it is on top of a 2 foot cut so to a deer it would hopefully look around 7 feet. I was considering extending the posts with wood sticks and more string lines if needed but haven't had a problem yet. I also read and have heard that you can put another low string a few feet in front of the low fence to really mess them up. They lose their springing area so apparently will not try.
The reason for the second terrace was that I put a cattle fence below and that was going to be my last area of land I claimed from the cows to keep with the cabin area. I only have 3 steers so I'm not much of a cowboy. Don't even have them home yet. I made the terrace to see how it would work out then put the cow fence a bit below it where it worked well. Since the terrace was now there I decided this year was the time to plant the fruit trees and get them growing.
I went with the string last year as I was not sure where the cow fence was going. This year I wanted a fence around the garden so it was string again. Wire fence is a lot of work and expensive. Deer netting fence is expensive. No climb fence is expensive. All permanent fences are a lot of work to take down if plans change .String seems to work just fine and it's reasonably cheap. I think bailer twine would be best as it will not likely rot in the sun from UV as fast. About a mile on a roll too as I recall.
I want to get olives here - maybe get a start from our tree in the valley. There are persimmons and olives near here in colder areas so I am sure they will do well here though I don't have them yet.
Talked to my renter/neighbor who said his dad did hugelkultur in Sweethome, OR. He learned it years ago from a possibly Mennonite neighbor he did some logging for. They saved the old trees to bury in the beds.
Stalk_of_fennel, the man at the lumberyard mentioned fishing line - string or anything for the deer. He said they didn't like things touching their ears or the wiggling strings - they didn't trust things that were unstable - a bit paranoid I guess.
The deer ate about a third of our garden in a few hours when we were gone a couple years ago. Since then we have had a 7 foot deer fence around the cabin garden.
Things to keep i mind about the Bobcat are that wheel varieties are kind of unstable sideways. Mine has widened wheels for the tracks and that makes it much more stable but it is still a possibility of tipping it over. They are great if you have a safe area to use them in. I don't know about the rubber tracked variety. The rocks here would eat $5000 worth of tracks in six months or so. On rental they would be OK. Note that I am about half crazy also and tipping over is not as great a scare as it should be - wear your seat belt to keep from getting thrown from the rig and smashed.
I am originally from Rose Lodge, Or. Family homesteaded there and still own land as well as live near there (Lincoln City).
Glad I could be of assistance - I like to share what I know as well as learn from the rest of you.
I'm also admin on Countryplans where Paul was good enough to share his
Hugelkultur video as well as others.
Here is my place for those who don't already know me.
