Why Finland is good at handling forest fires. It’s not because of raking

Eh What utter shit is this? There are no "Controlled Burnings" in Finland anymore. Just meticulous collecting (aka raking) and mulching loose material from clear cutting. The material is used in energy production.

The problem elsewhere (eg Sweden and California) is the "Green Forestry" principles, which prevent removing excess biomass from forests, and at the sametime a policy to actively suppress forest fires is enforced. This leads to an overly accumulation of biomass in trees and forest floors, which in turn makes forests vulnerable to raging and fast moving forest fires, when critical amount of biomass has been accumulated.

As I recall "Controlled Burnings" were quite popular in 1950s in Finland expecially around railroads, because steam locomotives were such a fire hazard.
