As speculation and scrutiny around potential drivers has increased, so too has a growÂing body of scholarly literature investigating the influences driving suppression costs.
This working paper provides an overview of the diverÂsity of drivers examined in scholarly literature that may influence suppression costs. The review indicates great variability in costs between comparable wildfires in the same season, as well as between comparable fire seasons. Much of this variation is unexplained by frequently noted drivers.
Suppression expenditure studies have consistently found that physical characteristics alone do not exÂplain observed variations in costs.
Recent studies illustrate how drivers that influence forest management and suppression strategy deciÂsions can significantly affect expenditures during wildfire suppression events.
Suppression expenditures include three drivers:
