Back again. Here are some replies to the issues that have come up in the last few posts.
Regarding the county-permit thing -- not an issue, partly because my county doesn't care, and partly because I'm not clearing the land, I'm thinning. We leave about enough trees to shade 50% of the land, but open up the other 50%. So at the end, i'm winding up with a few really big oak trees per acre instead of a bajillion little tiny trees. The insane part is that the oak trees never get harvested, which drives the professional foresters nuts when they talk to us. But that's the way Maw Nature had it before we got here and that's the way we'll leave it when Marcie and I kick off. Yep, this is a **long** project. We're hoping to have a good start at it, but it'll take 100 years to really get things right.
Regarding grazing with buffalo -- yep, that's a strategy that we've contemplated. We may do it some time, but that project will require repairing/installing about 5 miles of fences. On those same steep slopes. Another good job for the Mystery Device (although I'm starting to get confirmation that my Power-Trac plan is a good one).
Regarding the dozer -- yep, folks have it right. The dozer would set us back because it would disturb the ground. That's how the trouble got started -- loggers around here use dozers to skid logs off these steep slopes, which "plowed up" the ground and let the weeds take hold.
Regarding tracks on a skid-steer -- that's something I thought would work too, but I ran one up the hillside a couple weeks ago and it's just not gonna work on anything near the slopes I've got -- it pretty much crapped out at around 15-20 degrees.
Regarding the idea of letting the land return to normal on it's own -- unfortunately, once the exotic invaders get established they overwhelm the native stuff. Birch, sumac, aspen, buckthorn and the like are all really pretty but they don't "belong" here and have to be removed in order to give the native stuff a chance to reestablish itself. Once the native plants and trees are rockin' they can keep the invaders out, but we gotta give 'em a little help to get started.
Thanks Bob for the Ventrac scoop. That's amazing that you can hop around like that with only 3-4 inches of ground clearance. Makes me a lot more comfortable that the PT 1850 might just be the machine for me.
I think I'm gonna take this thread over to the PT forum and see what those folks think of my idea. Thanks for the info, lads.
