Nitrogen is inert. Combustion doesn't need nitrogen. It just basically fills space.

  As far as wildfires go, so is carbon dioxide. CO2 is not a typical reactant of combustion.

    Sure it does, it's a "product", so in principle it participates in the reverse reaction. This probably doesn't actually make a difference for combustion, although CO2 does apparently work a bit better than N2 for firefighting in spite of the added weight, but that seems usually attributed being heavier-than-air (heavier than O2!) and somewhat polar. Not sure how applicable that is to wildfires when it's the atmosphere, though.
