The escaped prescribed burn in New Mexico this year shows how this really isn't practical today with the Wildfire Urban Interface and current population densities.
Also if there was an easy way to quantify how much damage controlled burns have prevented vs the amount of damaged done by escaped burns like this I think we'd still find a net benefit
Lastly, I'd like to point out the difference between cultural burn practices and the controlled burns often practiced by firefighting agencies. The former are much smaller, cooler, and slower burns whereas the latter tend to follow specific lines and cover larger distances
Again this has no basis.
The prescribed fire that caused this 300k+ acre fire was supposed to be 1204 acres. That 1204 is the boundary of the possible burn area and the actual area burnt with even moderate intensity was probably planned to be much smaller.
