"Before 1800, several million acres burned every year in California due to both Indigenous burning and lightning-caused fires, far more than even the worst wildfire years today. Tribes used low-grade fires to shape the landscape, encouraging certain plants to grow both for tribal use and to attract game."
This addresses only a symptom (more extreme wildfires) and not the root issue: persistent drought / aridification amplified by climate change. To be resilient to the latter, we need to become dramatically more efficient in how we use water resources, especially in the food production pipeline.
After spending a lot of time in the Sierra Nevadas growing up, I really can see how a lot more trees are dying. A lot of it is that pine beetle wreaking havoc, but the number of standing dead trees is astounding. Old bike paths I used to fly down I now have to be careful on in case I round a corner and have a tree down; 20 years ago I just never had that cross my mind!
