Biology

Wollemi pines reproduce both sexually, through wind-pollination, and vegetatively, resulting in numerous trunks arising on a single tree (3). It may be that only the oldest trunks are able to produce seeds; female cones are observed year-round but male cones mature in late September and early October, releasing their pollen over the next few months (3). Seedlings appear to be slow-growing (3) and mature trees are extremely long-lived; some of the older individuals today are estimated to be between 500 and 1000 years old (2).
