No.
I would call the broad fields in Kansas and Nebraska maintained since tree stands separated by fields were laid out and required of homesteaders in the eighteen hundreds a heck of a firebreak.
Did you have some fantasy that someone from a long line of farmers would not know the history of the land and be able to bring it up on a forum?
Well, you failed. I do know.
The proper width of a fire break is (as I have repeatedly stated, and which you have completely ignored) determined by the normal maximum wind velocity. On the plains that is around seventy miles an hour, and in parts of California it is just as high.

I live the fantasy of having a retired California firefighter who fought these types of fires for 34 years.
