Table 1 Summary information of the ten fires surveyed for ponderosa pine regeneration across Arizona and New Mexico, USA, that burned severely in ponderosa pine forests. Field data were collected in 2018 and 2019. Within each fire perimeter, table includes total area burned in forests and woodlands, percent of area burned severely, the number of plots and transects established in high-severity burn patches, and ponderosa pine regeneration density (mean and median). High-severity fire was mapped using a RdNBR threshold of ≥643 (Singleton et al. 2019)
