Dead trees also obstruct movement of large animals such as deer and elk.
OK, this writer is an idiot. Can anyone here guess why deer fence, to be effective, must be over 8 ft tall ?
Now contrast that to the average fallen tree. Does this writer think most trees are over 8’ in diameter ? Even the fawns jump 4 ft or better.
Dead trees can fall on top of each other. The lumber pile of multiple ( thousands ? ) of large dead pine trees can be well over eight feet high and very wide.
