No, I am not assuming anything, I gave you the facts, so 4.7 bn trees was past year in Russia, Australia's 2019-2020 more than 10 million hectares of land burned, California 2020 4,397,809 acres (1,779,730 ha).

So, yes indigenous people used those techniques, to replenish forest but biologist say that 2019-2020 was not normal event. Especially considering number of animals burned was around 3 billion. https://www.bbc.co.uk/news/world-australia-53549936

So, of course they will stop burning when there is nothing to burn anymore, they will stop burning. Also our ability to plant new so far was not exemplary, and as I said, ability of sapling to sequester CO2 is very small. And each tree needs 15-20 years to grow to full size that can sequester more considerable amounts of CO2.

One more issue with trees worth mentioning is that past certain temperature, trees like humans, suffer a heat shock so they start dying. Which is again complication for growing new forest as saplings get exposed to higher temperature (not having collective cooling effect of fully grown forest) https://onlinelibrary.wiley.com/doi/10.1111/pce.12417
