Not just wilderness or undeveloped, but highly inaccessible to firefighting crews. The Bay Area has peaks over 4000 feet with lots of fairly sheer areas. Often firefighters have to be dropped in by helicopter.

Florida is mostly low rolling hills with the highest point in the state being ~350 feet above sea level. If Florida has a fire in an inaccessible area, it's usually inaccessible due to water, so more of a help to firefighters than a hindrance.
