That was done by hand for a long time - many centuries - in Germany's parklike forests, and I recall thought that the "waldsterben" forest dieoff might be related to that very long term, very meticulous removal of so much material.
I was employed at the UK's Coal Research Establishment (CRE) at the time when British and German coal fired power stations were being castigated as causing "acid rain" that was inducing "waldsterben" (forest death) in Scandinavia and central Europe.
Also, the waldsterben was discovered to have been a myth that was not happening.
But there was no enhanced acidity and no waldsterben near and/or downwind of the power stations.
