They're not naturally occurring, they're set either accidentally or intentionally by humans for the most part, either to clear the land or in the process of stealing stuff (either from plantations, or as plantations, depending on your politics). The scary thing is people are draining the peat bogs; if those catch on fire (peat is a great fuel, basically dirty coal), a lot of carbon goes into the atmosphere which would otherwise have been sequestered for centuries+. I'm fine with small wildfires clearing out fuel in a place which otherwise builds up fuel for bigger fires, but that's not Indonesia.
