Large, uprooted doug-fir laying into another doug-fir... thoughts?

I think walking the tree has the downside of wanting to relocate the butt closer to the support tree each cut despite hinge setting, possibly ending in vertically hung. Mofo winch gives the option of keeping 45 degree (vertical on the failed tree) tangle which would hold until slipped out so the prep would be cleaning out the "hook" snag branches/stubs from the failed tree's tangle. Up close visual could confirm whether such prep/extraction could be achieved. Maybe it's too velcroed.

A hinged root plate cut could use the settling of the soil chunk to give the first tug on getting the trees pulled apart.

From the looks of it, it seems to be more of a soil failure than tree failure. Sumthin I wish were discussed more

That makes up the majority of doug fir failures I see in living trees, and even out here with our thin soil, it doesn't happen super often. I sure wish there was a better way to diagnose it before hand. Lots of clay and bedrock, with a very thin organic layer on top.

Not too long ago, I gave an assessment report on a DF perched on the edge of a bluff. A good sized root grew parallel to the edge with ample huge surface roots inland.
The report basically said the tree is low risk of tree failure, with a lot of words about soil failure.
 
Now that I’ve seen the pictures I’ve got a totally different idea of how to do it. Even if you have low ground anchors I think using a grip hoist winch or power puller to a guy rope or two could get a lot of pressure off the supporting tree.

What is the soil like under the log? From the bracken fern I see it could be a bit soft? I would suggest also using a bunch of cribbing to spread the load out and put a jack with a post pushing up on the log. 20 ton jacks can do a lot more than ropes especially with that trunk angle. On the tree that was the cover photo on the last Wesspur catalog ever we did that to free the tree from the roof and it worked awesome.
 
Looks like a lot of jobs I rolled up to post Helene. Pretty simple to work out. Climb out of the hung up tree, brush out the leaner, get it down to the trigger cut, cut last little pressure point from the bottom and get ready for a little ride. Make sure your chain brake is operational and your climb rope is clear of the falling tree.
 
Are the three evils to choose between - brush out and drop/trigger spar munching support tree bark, jack/rope support brush out bomb spar chunks onto support root plate, partially brush out de-hook and hopefully less damage support tree bark during winching butt away/trigger?
 
I think I could do the whole thing without any significant damage while solo.

Having my employee to help would be helpful.

I'm just weighing options.


Tricky, but fully possible.

Trying to suss out what my options are and best plan.

They have 46 trees on the bid. 42 are dead/ dying alders or future dead dying alders.

They can't afford to do them all.

He's going to see which can wait, and which he can handle.


The doug-fir doesn't threaten anything but the support tree over time.

Well looky what popped up on my youtube feed randomly. The algorithm is a bit too dialed in to my life. Cool job. Its always nice to work with a competent crew.

Yup, that was a fun tree. It was one of the craziest trees of my career that also kind of boring because of how smoothly the job went. Having a huge budget because it was covered by insurance certainly helped. I brought in 2 top level contract climbers and another tree service to assist. Not having to stress about economics just made it so we could just be slow and steady and do what needed to be done to mitigate all the hazards.

When I bid it I didn’t think the crane could reach it so we were fully planning on it being a total rig down removal. Glad we were able to get the crane there.
