Variable importance to wildfire severity assessed by Boruta feature selection algorithm wrapped around Random Forest regression (RFR) against the shadow variables (shadowMin, shadowMean and shadowMax) in the untreated buffers surrounding PB treatments. The boxes in green represent variables marked as confirmed by the Boruta algorithm, in yellow as tentative, and in red as unconfirmed
