This is one of these "Save the forest by burning it" situations that

To save a forest firefighters often cut a few tree. Don't cut all the
trees in a forest to save it from a fire.
Seasonal work, many solar obits past.
Well, actually, standard practice is to scratch a line and burn out
from the line to reduce fuel proximal to the line. "Scrach" can take
the form of a crew with hand tools scratching a width-of-tool
reduction in fine fuel to tandem tractors scratching width-of-blade,
followed by walked drip torches. Trees don't really "burn" and cutting
trees to make line is only useful when attempting to limit crown fires
more effectively dealt with by retreat to a discontiguous canopy and
firing out to reduce propagation over fine fuels.
Modernly, fire is recognized as a natural phenomena and past fire
suppression doctrine has elevated fuel load and fire intensity, with
deleterious effect, and suppression goals modified to structure
defense, and identified resource defense, as well as the ongoing
timber sales value defense.
