The president was seemingly echoing some language from a longstanding argument between California's farmers and environmentalists over how the state's water resources should best be shared.
"California wildfires are being magnified & made so much worse by the bad environmental laws which aren't allowing massive amount of readily available water to be properly utilized. Must also tree clear to stop fire spreading!" Henri Grissino-Mayer, a geography professor at the University of Tennessee, said he had "no clue" what Trump was referring to in his tweet.

So far this year, US fires have burned 5 million acres (2 million hectares), much more than the 10-year average, according to the National Interagency Fire Center. "These hazards, along with extreme fire behavior and frequent weather changes, have made this an extremely hard fire fight", according to the NPS statement. But the heat forced many crews to drop back to safety zones in July and helplessly watch fires continue to rapidly expand. That was only about 10 percent higher than that the 3,440 last year and the 3,405-acre average for the last 5 years.
