Table 1 Wildfire metrics adopted to perform the cluster analysis
From: Uncovering current pyroregions in Italy using wildfire metrics
Wildfire metrics | Definition | Codes | Description |
|---|---|---|---|
Fire density | Wildfire/Fuel | W/F | Ratio between the average number of wildfires per year and the land area with available flammable fuel (n × km−2 × yr−1) |
Burnt area/Fuel | BA/F | Ratio between the average burnt area per year and the land area with available flammable fuel (ha × km−2 × yr−1) | |
Mean BA/WE | BA/WE | Mean burnt area per wildfire event (ha) | |
Fire seasonality | Seasonal Wildfires | SeaW | Ratio between the number of wildfires during the main fire season (winter in Northern regions and summer in South Central regions) and the total number of wildfire events |
Seasonal Burnt | SeaB | Ratio between burnt area (ha) during the main fire season (winter in Northern regions and summer in South Central regions) and total burnt area | |
Other seasonal wildfires | OSeaW | Ratio between the number of wildfires in seasons others than the main fire season and total number of wildfire events | |
Other seasonal burnt | OSeaB | Ratio between burnt area (ha) in seasons other than the main fire season and total burnt area | |
Stand-replacing fire | Stand-replacing fire ratio | SRF | Incidence of forest cover loss caused by wildfire occurrence |
