The vast majority of forest land in California is owned by the federal government and is National Forest land. California can't just go and run controlled burns in those federally controlled forests. That would need to be done in cooperation or under the direction of the US Forest Service and should be funded by the US Forest Service since they own the land.

If the federal government wants better forest management in the National Forests, they should increase funding for forest management and hire more employees into the US Forest Service.

You can certainly blame California for allowing people to build homes at the wildland urban interface and for not requiring homeowners to take better fire defensibility measures. The forests are a more complicated issue and the feds take much of the blame.
