I have and it still bothers me.
Towards the end of my AT thru I was caught late in the afternoon in fading light and set up my hammock near Crescent Pond, Maine. We picked a spot where my hiking partner could also set up his tent.
The ground was very spongy and there were quite a few fallen trees in the area. The head end of my hammock attached to a tree of about one foot diameter and about 40 ft tall, foot end to something smaller.
It rained all night and in the morning I noticed that my tarp was very loose and my underquilt was just touching the ground.
When I got up I noticed that the roots of the larger tree had lifted about an inch out of the ground, the tree had tipped over and the top was snagged in an adjacent tree.
I am very carefull to use LNT and now I might be resposnible for killing a tree, thats what bothers me the most.
I am not sure that the tree was not already dead, there were needles high up but not a whole lot of them.
So now there is one more thing I look for, I make sure that the soil around the tree roots is not too loamy. I have always used smaller trees to mitigate lightning risk but this one was not particularly small.
Just wondered if anyone else had a tree fall or is it just me.
