Differences in tree seedling density by species calculated as unmulched density subtracted from mulched density on six fires across the US Interior West in 2015 and 2016. Only plot pairs with non-zero values were included. Note scale difference for lodgepole pine compared to the other species. Any point above the zero line represents a higher value on the mulched plot, while a value below the line is a higher value on the unmulched plot of the pair. Circles represent suspected outliers, datapoints beyond 1.5 times the interquartile range
