The ground parrot
The cryptic, ground-living heath parrot you hear at dusk and almost never see — a true wallum specialist that needs large, connected tracts of heath of just the right age since fire, and has retreated to strongholds like Cooloola as that country is cleared, fragmented and burnt wrong.

The ground parrot is a slim, grass-green, barred parrot of the wallum heath that you will almost certainly hear before — or instead of — ever seeing. It has given up the trees to live its whole life down in the heath, creeping through the low scrub and flushing only at the last second in a jinking flight before it drops back into cover. It is fussy in a very particular way: it needs large, unbroken heath of the right age since the last fire — long enough unburnt to be dense and seed-rich, but not so long that it has grown rank and woody. Burn its heath too often, or too rarely, or chop it into fragments too small to hold it, and the parrot quietly disappears — usually without anyone ever having seen it there.
Somewhere in the low heath, quite possibly only a few paces from where you are standing, is a bird you are very unlikely ever to see. The ground parrot is a slim, barred, grass-green parrot that has done the unparrot-like thing of giving up the trees entirely to live its whole life on the ground, creeping through the thick of the wallum and taking flight only when almost stepped on, in a low, jinking flush before it drops straight back into cover. What usually gives it away is not a sighting but a sound — a thin, rising series of piped notes carried across the heath at dusk and dawn. It is one of the truest specialists of the sand country, and one of the fussiest.
What it is fussy about is the state of the heath, and the state of the heath is decided by fire. A patch of wallum is not a fixed picture but a slow cycle: bare and open just after a burn, then thickening, then dense and heavy with seed, and finally — if left unburnt far too long — rank, leggy and drained of the seeding plants that fed it. The ground parrot needs the middle of that cycle, heath old enough to hide and feed in but not so old that its food has gone. So the fire is everything. Burn its country too often and it never ages into the dense, seed-rich stage the bird requires; leave it unburnt too long and the heath goes rank and empty. In either direction there is simply nowhere for a ground parrot to be.
And it needs that country not only at the right age but in bulk. A ground parrot ranges widely to feed, and only a large, connected tract of heath can hold a patchwork of ages so that some corner of it is always at the right stage — while a small, isolated fragment can be flipped, all at once, into the wrong stage by a single fire, with no heath of the right age next door to retreat to and no way to cross the cleared ground between patches. Large heath, connected heath, burnt on a varied rhythm: that is the exact thing the cleared, chopped-up, wrongly-burnt modern landscape has been taking away, which is why the ground parrot has pulled back to strongholds like Cooloola and why it is listed as vulnerable. Get the fire, the water and the space exactly right and it holds on, unseen. Get any one of them wrong, and it is gone without a sound.
In depth — the mechanism
The ground parrot (Pezoporus wallicus) is the wallum's requirements made flesh. It is a slender, barred, grass-green parrot that has done something almost no other parrot does: given up the canopy altogether to spend its entire life on the ground, creeping and running through the low heath and taking wing only when nearly trodden on, in a brief, low, jinking flush before it pitches back into cover. You will hardly ever see one. Its presence is given away instead by voice — a thin, ascending series of piped notes delivered in the half-light of dusk and dawn — which is how surveyors find a bird that is otherwise a rumour in the scrub. It eats the seeds of the sedges, grasses and small heath plants of the wallum floor, and it is one of the most demanding specialists on the whole coast.
Its dependence is a dependence on structure, and structure here is set by fire. A patch of wallum is not a fixed thing; it cycles through stages as it ages away from its last burn — open and bare just after fire, then thickening, then dense, seed-rich and ideal, then, if left far too long, rank, leggy and senescent, its seeding ground layer shaded out (see fire-mosaic). The ground parrot needs the middle of that arc: heath old enough since fire to be thick enough to hide in and productive enough to feed in, and not so old that the seeding plants it lives on have gone. That is why the fire regime is life or death for it. Burn too often and the heath never grows past the thin, open, foodless stage; leave it unburnt too long and it goes rank and empties of seed. Neither extreme has anywhere for the parrot to be — and this is fragile in a second way, because the bird also needs the heath in quantity. It forages over wide areas, and a large, connected tract can carry a spread of patch-ages so that some of it is always at the right stage; a small, isolated fragment can be tipped wholesale into the wrong stage by a single fire, with no neighbouring heath of the right age to fall back on and no way for birds to recolonise across cleared ground.
Put the two together and you have the exact combination the modern landscape has been taking away: large, connected heath, burnt on a varied rhythm matched to the country. Clearing removes the heath; fragmentation strips out the size and the connection; and fire regimes that are too frequent, too rare or too uniform flatten the age-mosaic the bird rides. As that country has gone, the eastern ground parrot has contracted to a handful of strongholds, of which the wallum of Cooloola and the wider Great Sandy region is among the most important, and it is listed Vulnerable (Qld Nature Conservation Act 1992 and the EPBC Act). It is the clearest animal illustration on the coast of why there is no single right fire — and of the wider truth that you rarely save a species by managing the species: to keep the ground parrot you keep the wallum, whole, large and burnt well (see species-dependence).

The ground parrot needs large tracts of wallum heath of intermediate age since fire. A manager burns its heath on a short, uniform cycle — every couple of years, everywhere. Predict what this does to the ground parrot, and why.
A patch of wallum cycles through stages as it ages away from its last fire — open and bare, then thickening, then dense and seed-rich, then eventually rank and drained of seed. The ground parrot needs the middle of that arc, so the fire regime is life or death for it. Burn too often and the heath never ages into the thick, productive stage — there is no cover and little food, so the bird cannot persist; leave it unburnt far too long and the heath goes rank and empties of the seeds it eats, which is just as fatal. This is the fire-mosaic concept made flesh: there is no single right fire, and a too-uniform, too-frequent regime drops the whole heath onto one wrong point of the cycle at once (Dooley et al. 2023 show fire frequency as exactly this master switch on heath structure). The danger is worse in small, fragmented patches, where one fire can flip all the heath into the wrong stage with none of the right age nearby to fall back on. The distractors invert the biology: the parrot lives on the ground, not in hollows, and needs seed-rich cover rather than bare ground or acid water. (Ch 9.)
