This research covers three broad categories of wildfire costs. To estimate the cost of wildfires in New Zealand, BERL integrated two models, the Least Cost plus Loss (LC + L) model and the Cost plus Net Value Change (C + NVC) model. This research integrates these two models in order to capture both the immediate effects of wildfires as well as the medium and long-term economic costs. Additionally the economic cost has been divided into pre-suppression, suppression, and after fire costs. Suppression costs refer to the resources used to fight wildfires and after fire costs reflect the damage resulting from wildfires. Pre-suppression, or fire prevention, is not a direct cost of wildfire, but it is included as a third cost category in this research. Pre-suppression reduces the probability of wildfires and the associated fire damage.
