In prehistoric times, wildfires would very occasionally sweep through areas of pine woodland. Most trees in the rainforest grow rapidly to escape the darkness of the forest floor and understory and to reach the needed sunlight of the canopy. while the other moisture comes from the coastal fog that lingers on the trees.
