The biggest problem has been reducing the ladder fuel (underbrush etc). The fuels dept is notoriously understaffed and underfunded for national forest service. On top of his, it's difficult to convince locals to deal with lots of controlled burns in winter and spring.
Logging practices have gotten better, especially with dispersed thinning, but my gut is hat climate change is the real culprit.
Also, lodge pole pine is becoming more dominant in the PNW, and we're losing more fire resistant (and dependent) trees like ponderosa. Lodge pole grows like a weed and burns like hay.
Couple this with an antiquated federal service entirely dependent on chain of command that fights every year to preserve operations and their career posts and you get one of the most wasteful inefficient services in U.S. Govt.
