Do you have any sources for this? I am familiar with people who manage private properties on federal lands and nothing you said here passes the smell test to me. In particular, environmental groups have been loudly calling for better wildland management practices for at least the past decade, typically from the direction of considering and adopting indigenous land management practices such as prescribed burns.

It sounds like you're trying to scapegoat environmentalists when the recent tragedies were obviously the fault of PG&E mis-managing their assets and refusing to allocate more budget or personnel to manage what are obviously tinderbox scenarios.
