Table 2 Weather conditions and fire behavior parameters for the prescribed burns and bushfires that occurred on the Swan Coastal Plain north of Perth, Western Australia, Australia, that were studied from 2017 through 2019 to compare resulting availability of seed from B. attenuata and B. menzeseii. Note that the rates of spread listed are for headfire; flank fires spread at approximately half the headfire rate of spread. Burn = prescribed burn, Fire = bushfire, NR = Nature Reserve, SF = State Forest, Rh= Relative humidity

From: Prescribed burning in a mediterranean-climate region mitigates the disturbance by bushfire to a critical food resource for an endangered bird, the Carnaby’s cockatoo
