Table 1 Characteristics of the four shortleaf pine stands used in the field study. All litter collections occurred following fall burns and prior to spring burns; “burned litter” was taken from the fall burn treatment plot in each block, and other litter samples were averaged across the three other treatment plots
From: Direct and indirect effects of fire on germination of shortleaf pine seeds
