A species

Bunya pine

The great dome-crowned araucaria whose crown rides clear above the canopy and whose enormous cones — five to ten kilograms apiece — fall heavily every few years. A Gondwanan relic, a local hinterland native, and a tree whose present range still carries the mark of people carrying its seed.

The bunya pine is the huge, dark, dome-topped conifer that stands clear above the rainforest like a great green umbrella. Every few years it does something spectacular: from high in its crown it drops cones the size and weight of a football — five to ten kilograms each — packed with big, starchy, edible seeds. It is a cousin of the hoop pine and just as ancient. Its stronghold is the Bunya Mountains inland, but the Blackall Range hinterland is one of its natural homes too, so a bunya here is a genuine local, not a stray.

Now and then a rainforest tree steps out of the canopy and becomes an event. The bunya pine, Araucaria bidwillii, is a huge, dark, dome-crowned conifer — a cousin of the hoop pine and a survivor of the same Gondwanan line — and where the hoop pine spears up as a pale spire, the bunya rides above the forest as a great rounded green dome you can pick out from a long way off. Its famous stronghold is the Bunya Mountains, inland and to the north-west, but the Blackall Range and the Maleny hinterland were one of its natural homes too, so a bunya standing over a gully here is a genuine local and not a stray from somewhere else.

What makes the bunya the bunya is what it does every few years. In a mast rhythm — very roughly one heavy crop in three — it bears, high in that dome of a crown, cones the size and weight of a football: five to ten kilograms of woody cone apiece, each packed with thirty to a hundred big, starchy, nutritious seeds. When they let go they fall like cannonballs, and standing under a fruiting bunya in the wrong season is a genuinely bad idea. That great episodic crop is the heart of the tree’s ecology. A seed this large and this rich, dropped straight down, lands in its parent’s deep shade with no future; so the bunya, like so much of this forest, depends on something to carry its seed away and give it a start somewhere new.

Over the long run its most important carrier was people. Kept strictly to what the published record holds: in good cone years Aboriginal people travelled long distances to gather and share the abundant seed, a well-documented feature of the historical record, and recent genomic work reads the tree’s present spread across south-east Queensland as partly the mark of that harvest — seed carried and established by human hands, the pattern widening further after colonisation. That is as far as the evidence takes us, and as far as this book goes: the ecology of a remarkable seed and the documented history of its dispersal, with nothing added. A great dome above the canopy, a football-sized cone waiting to fall, and a map of the species that people helped to draw — the bunya is old beyond easy reckoning, and its story is still partly ours.

In depth — the mechanism

Araucaria bidwillii is the bunya, a huge, dark, dome-crowned conifer and a cousin of the hoop pine — the two are araucarias, survivors of the same Gondwanan line that predates the flowering trees (see rainforest-structure). Like the hoop pine it rides clear above the rainforest canopy, but where the hoop pine is a pale spire the bunya is a great rounded green dome, unmistakable from a distance. Its stronghold is the Bunya Mountains, inland and north-west of the coast, but the Blackall Range and the Maleny hinterland were one of its natural centres too, so a bunya standing over a hinterland gully is a genuine local rather than a planted stray.

What sets the bunya apart is its cones. Every few years — a mast rhythm of roughly one heavy crop in three — it bears enormous cones high in the crown, each about the size of a football and weighing five to ten kilograms, packed with thirty to a hundred large, starchy, nutritious seeds. When they fall they come down like cannonballs, which is reason enough to keep clear of a fruiting tree in season. That heavy, concentrated, episodic seed crop is the centre of the bunya's ecology and of its dependence on dispersers (see plant-partnerships): a big seed that simply drops beneath its parent lands in the deepest shade, so the tree relies on things that will carry the seed away — and its most consequential carrier, over the long run, was people.

Here the record is kept deliberately narrow, to what is published and public. In good cone years, Aboriginal people travelled long distances to gather and share the abundant seed — a well-documented feature of the historical record (Cooke et al. 2024). And recent genomic work reads the tree's present-day distribution across south-east Queensland as partly the fingerprint of that harvest: seed carried and established by people, with the pattern broadening further after colonisation (Fahey et al. 2024). That is the whole of what belongs here — the ecology of a great dispersal partnership, and its documented history — with no ceremony, story or cultural detail invented or embellished beyond those published sources. The bunya reads, in the end, as an ancient tree whose modern map was written in part by the animals and the people that valued its remarkable seed.
