Also, these are to a large extent not “natural forests”; these forests can be huge areas of human planted forest with vast areas being covered by trees all the same age and size. This could mean it burns faster and recovers slower than a natural forest.
Also in natural land there are natural borders such as wetlands to limit spread, and if those wetlands have been ditched to increase forest area then the reach of the fires will grow.
But you are absolutely right this is a human problem not a forest problem. Humans live in these areas, and live off these forests. Not seldom the people whose homes are threatened by the fires are also landowners whose livelyhood is the forest itself. That the ecosystem grows back cyclically is no comfort, they expect their homes and livelyhood to be protected.
