Interesting Observations

  • billions of dollars are spent on fighting wildland fire.
  • the big drop of wild fire in 1985 is strange, can we find explanations.
  • While the number of fires are more stable in the past 20 year, the amount of burned land has been growing in the past five years. Meanwhile, the budget is also growing (almost non-linearly in recent years). It would useful to explain which department, Department of the Interior or Department of Agriculture, is taking the primary role in fighing wildland fire and should receive more budget allocation.
