Nearly all of the very large wildfires are caused by human doctoral thesis betekenis during periods of very hot, dry easterly Santa Ana winds.
These man-made fires are commonly caused by drought line failures, vehicle fires and collisions, sparks from machinery, arson, or campfires. In natural Chaparral communities without human interference, the fires are ignition-prone as there are plenty of ground fuels and the temperatures are fire-permitting during the dry season. Though adapted to infrequent fires, chaparral plant communities can be exterminated by frequent fires. A moderate frequency of fire less than ten years will result in the loss of seeder theses such as Manzanita spp.
This moderate frequency disallows seeder plants to reach their reproductive size before the next fire and the community shifts to a sprouter-dominance.
High frequency fires less than five california can cause the additional loss of sprouters by exhausting their reserves below-ground.
