Fig. 6From: Northern spotted owl nesting forests as fire refugia: a 30-year synthesis of large wildfiresFrequency distributions of relative differenced normalized burn ratio (RdNBR) values, skewness, and kurtosis measures for nesting/roosting cover type in the 4 years with the highest area burned among 472 large (≥ 200 ha) wildfires in the range of the northern spotted owl, USA, 1987–2017. Higher RdNBR values indicate higher burn severityBack to article page
