So I was looking at google Earth and I happen to just like be looking at some wooded area and I was wondering. Do we cut down all these trees and leave them or what actually causes so many trees to fall like this? I cant place the image but I can give coordinates on google Earth?
Tree borers are a group of insects that lay their eggs on or inside of trees, where the young larvae eat their way through living tissues. ... Tree borer insects cause affected parts of trees to slowly weaken as their chewing severs vital transport tissues
I say some kind of water event started the erosion process which disturbed the roots . As the trees eroded it became a larger drainage issue that cascaded .
Pine trees + shallow soil = no depth for stability
Pine trees also need deep soil to sink its roots into for stability. A pine tree’s root system can extend away from the tree at a distance as much as twice the height of the tree. (U.S. Department of Agriculture) Pines, notably Ponderosa pines, tend to have a deep tap root with a much shallower (12″ inches or shallower from the ground surface level) root system. The shallower roots follow cracks and water spots for the pine to quench its thirst.

Two things I just noticed . It looks like the root system failed which will cause a tree to topple over . I can’t find any insect that would cause that. But there’s a site here explains even minor disturbance in the soil can kill the roots.
Now look at the ground in that area. In the earlier picture there are some areas that are a yellowish color and look like mud. In the current picture everything looks like mud . If I had to take a second guess.
I say some kind of water event started the erosion process which disturbed the roots . As the trees died it became a larger drainage issue that cascaded .
That’s what I’m going with unless someone can find a bug that attacks the roots .
Why do pine trees fall over
