Truth is when I took forestry and conservation courses in 1970 (!) we discussed that the redwoods and sequoias would be lost some day if they did not harvest the douglas fir and other understory trees that were being protected by the tree huggers who did not understand the ecology. Both are fire dependent species that need fires to clear the underbrush and the cambium is protected by a thick bark layer that protects them from the heat. Let the underbrush accumulate and the bark burns, the cambium is damaged and you eventually lose the tree sometimes thousands of years old. This is true of almost all fire dependent habitats which comprises most of California, both forest and brush lands . They have been needing to manage these landscapes for the last 50 years, at least… like when we discussed it in forestry school in 1970.
