Travis,
I am hoping the whole tree will survive (these are 90% sweetgum and a few tulip polar and water maple), thus giving me living crossbars as well. We are not quite as wet as you are but my suspicion is that a dead sapling low bar will decay about within 1-2 years and then I will be left with uprights that are alive but I will have to replace the crossbars, especially the important lower ones. And the VINES here, my gracious, are likely to make replacement impossible. I was thinking about just making a thicket fence, providing supports for the thorny wild roses which are already present and clearing out the overstory a little to make them grow like crazy. That is kind of my plan B, if the lain over trees die, the vines will probably do the trick. I have some areas of impenetrable vines and the deer do not challenge them, and the autumn olives seem to find their way in there for nitrogen fixation. I think based on naturally lain sweetgums (taken down by falling pines) they often stay alive with severe damage and send up verticals to make new trunks. Those I can lay over as well once the tree recovers. The fact that the sweetgums are suckers from rhizomes may make the colony cut it's losses and stop resourcing that trunk, or it may provide nutrition for the repair. I have to wait and see. The good news is that I need only wait 2-3 years for more sweetgums of the same size all over the place! I have become an artist at using them at this point. I have a corduroy road going hundreds of yards and fill it in anywhere I am felling. Unfortunately they are structurally useless (worse than poplar) so milling is a waste. It's why chipping is so tempting, they are by far the best biomass producer here. I am planning a WO-BAA-TI (working name) for the sheep, but termites here are aggressive and I will have to use borates and massive timbers even for a small structure. Span strength is about 1" diameter per foot of span.
What I am sort of aiming for is an area that is foxproof, which is a higher standard by far. I am working to hedge off the main forest garden area (about an acre) with only one tight access point and then have guineas in there. I know they will tend to go all over but if I raise the keets in there they should consider it their home (I hope) and maybe I can keep some of them around. The ticks here are preposterous, it was not unusual to get 30-40 on me on a brief walk in the woods, and we have lyme and babesiosis (about 20% of ticks) and some new one they haven't named yet but seems to be real. I'm using permethrin impregnated clothing and have had zero ticks using that but I would like to not be relying on it. Doesn't seem permi-approved but is much more reliable than pyrethrins (which I had to apply each time and was irritating). I think with the native roses I can get a really tight and nasty hedge. After a few years they seem to be structurally strong enough to support themselves even if the whole wood fence degrades.
