Let's hope they are a bit more wise in managing the wildfires in the future than they were in the 20th century.
https://www.theguardian.com/commentisfree/2020/sep/14/california-fire-suppression-forests-tinderbox Before this unprecedented era of mega-blazes on the US west coast, California’s forests had a canny, ingenious way of avoiding destructive worst-case forest fire scenarios. By periodically removing the grasses, shrubs and young trees – known as the forest understory – California <https://www.theguardian.com/us-news/california> avoided fires growing to destructive intensities before the 20th century. The way this was done? Fire. Every five to 15 years, groundfires would burn through the forest, killing off the undergrowth on a regular basis, thus removing the material that can act as tinder and kindle fires. Such groundfires were sparked by lightning or by indigenous people who used sophisticated burning practices to facilitate crop growing and hunting. Because the fires occurred frequently, the understory rarely had time to build up enough combustible material for the fires to reach the canopies of the mature trees – which is what causes the large, devastating fires we are seeing now. As a result, overstory trees might get wounded by the groundfires, but they would rarely get killed.
