Banksia serrata
"Banksia serrata" occurs on the Australian mainland from Wilsons Promontory, Victoria (39°08′ S) in the south, to Maryborough, Queensland (25°31′ S) in the north. There is also a large population at Sisters Creek in Tasmania and another in the south west corner of the Wingaroo Nature Reserve in the northern part of Flinders Island. The Wingaroo NR Conservation Plan (2000) reports that the population comprises around 60 to 80 individual trees, the majority of which are believed to be "quite old". It adds that there is evidence of slow and continuous regeneration, which appears to be occurring in the absence of fire.
