Guides

Deep time in the rock

Eight hundred million years compressed into one blue wall behind the city — a stalled rift, two ice ages that iced the whole planet, the first known animals, and a young fault system still lifting the land under your feet.

Fire country

The third force of the Adelaide summer — a country the bush was built to burn, that answers flame with a resurrection kit of its own, and that a crowded, warming range front is still learning how much of, and whose hand should light.

Reading absence

The hardest skill this book asks of you — seeing what is no longer there: the vanished mammals, a baseline that keeps sliding before anyone notices, and debts still quietly being paid.

The drought engine

A belt of high pressure that parks over Adelaide every summer and slides away every winter — the Mediterranean bargain of wet-winter, killing-dry-summer that every living thing here is built to survive.

The ecosystems — the worlds the gradient builds

Stringybark country

The forested spine of the Mount Lofty Ranges — a wet island of the past, marooned by drought and holding on, that is quietly emptying of its woodland birds.

The fern gullies

The deepest, dampest creases of the ranges — permanent-shade creek gullies of tree ferns and one-cell-thick filmy ferns, the faint, diminished cousins of rainforest holding on inside a Mediterranean summer.

The Fleurieu peat swamps

Spring-fed peat swamps in the wettest folds of the southern ranges — an acid sponge built by centuries of waterlogging, and the last stronghold of the Mount Lofty southern emu-wren.

The rain-shadow mallee

Over the crest and into the dry lee — low, multi-stemmed lignotuber eucalypts standing over spinifex and saltbush, the toughest community on the gradient, and the one farming least managed to finish off.

The seagrass meadows

The drowned forest carpeting the gulf floor below the tide — Posidonia and Amphibolis meadows that nursery half the gulf's seafood, bank carbon in the dark, and shelter a fish dressed as a frond of weed.

The vanished grassy plains

The open blue-gum-and-grey-box grassy woodland the colonists found across the Adelaide Plains is almost entirely gone — learn to read the lone paddock tree, the fenced verge and the roadside grass strip as the last four per cent.

The places — real ground you can stand on and read

Barker Inlet

The tidal estuary north of the city, laced with mangrove and saltmarsh, that was set aside in 1973 for the plainest of reasons — the gulf's prawns, whiting and blue swimmer crabs are all born here.

Cleland — the range front

A five-minute walk below the Mount Lofty summit where cleared paddock gives way, almost at a step, to intact stringybark-and-pink-gum forest — the range front you can cross on foot, leaf in hand.

Hallett Cove — the glacial pavement

A coastal reserve where a bare rock floor, grooved and polished by an ice sheet, sits directly on the tilted, half-billion-year-old wreckage of the rift basin that built the ranges — two ice ages and a lost mountain range in one clifftop walk.

Karrawirra Pari — the Torrens

The city's river, dammed into a lake to hide the fact that it runs dry every summer — and the single clearest reason a Mediterranean-climate city built reservoirs, pipelines and a desalination plant rather than trust the creek it was founded on.

Morialta — a hills gorge

A fault-cut gorge on the range front, twenty minutes from the city, where a creek runs hard after winter rain, ferns keep to the shaded floor, and a dry February waterfall is telling the truth, not failing.

Mount Lofty summit

A railed lookout a little over 710 m above the plains where, on a clear day, the whole gulf-to-range argument of the book lies open in front of you at once.

Ngarkat — the great mallee reserve

More than a quarter of a million hectares of unbroken mallee scrub in the Mount Lofty rain shadow, once written off as the Ninety Mile Desert — now the largest block of native vegetation left standing in agricultural South Australia.

The Hills Face scarp

The blue wall behind the city is not scenery but a fault scarp mid-stroke — the torn edge of the Eden-Burnside Fault, kept green by a planning line and still, slowly, rising.

The samphire coast

The salt-soaked frontier where Gulf St Vincent meets the plains — samphire flats, the world's most southerly mangroves, and a mudflat larder that fuels shorebirds all the way to the Arctic.

The St Kilda mangroves

A boardwalk through the world's most southerly grey-mangrove forest, north of Adelaide — and the 2020 brine dieback that showed how finely balanced life at the salt limit really is.

Winaityinaityi Pangkara — the bird sanctuary

A stretch of tidal flat and saltmarsh north of Adelaide, proclaimed in 2016 as the Adelaide International Bird Sanctuary — Kaurna name Winaityinaityi Pangkara, 'a country for all birds' — where tens of thousands of shorebirds make landfall at the southern end of a hemisphere-spanning flyway.

The species — who lives here, and what each depends on

Birds

Adelaide rosella

The everyday orange-and-blue parrot of the hills and suburbs — a natural hybrid between the crimson rosella of the wet ranges and the yellow rosella of the dry river country, and the bird most people mean when they point at a backyard gum and say 'nature.'

Grey plover

A modest grey-and-white wader that fattens on Adelaide's mudflats and then flies thirteen thousand kilometres to breed in the Russian Arctic — the flyway made flesh.

Malleefowl

A shy, chicken-sized mound-builder that runs a compost-heap incubator by beak and foot for months on end — one of the very few birds on Earth that never broods its own eggs, and in trouble as the mallee it depends on is cleared and burnt.

Mistletoebird

A tiny red-and-black bird that eats almost nothing but mistletoe berries, digests the seed in minutes, and wipes it — deliberately — onto the very branch it is sitting on: a dispersal partnership tuned to exquisite precision.

New Holland honeyeater

A sharp, black-and-white, quarrelsome nectar-drinker — one of the region's most persistent flower-workers, and the common, everyday face of a pollination bargain rarer species are losing their grip on.

Superb fairy-wren

The cocked-tail blue-and-black wren of gardens and reserves — common, cooperative and unfussy about canopy, but a small, honest field test of whether a patch still keeps its dense low cover.

The mallee emu-wren

A four-gram scrap of a bird that cannot fly across open ground and will not live anywhere but old, unburnt spinifex — wiped from South Australia by a single 2014 fire, and carried back across the border by hand from 2018.

The Mount Lofty chestnut-rumped heathwren

A ground-hugging bird of the wet heath, so isolated in the Mount Lofty Ranges that it has become its own endemic race — known from only a handful of sites, and undone by exactly what undoes the emu-wren beside it: open ground, and shrinking cover.

The slender-billed thornbill

A dun, unremarkable-looking little bird bound so tightly to Gulf St Vincent's samphire that it is listed as vulnerable — and, in 2024, found holding on in more places than anyone knew.

The southern emu-wren

A tiny, secretive bird with a filamentous tail like six wisps of a moulting emu, bound to the dense sedgy swamps of the high Fleurieu and Mount Lofty country — a living token of the ranges' wet refuge, and of how little of it is left.

White-fronted chat

A small, sharp-suited bird of the open samphire and saltmarsh flats, bouncing low over the crimson ground on a thin, tinkling call — proof the 'wasteland' coast has specialists of its own.

Yellow-tailed black-cockatoo

The great wailing, half-metre-long hollow-nester of the Mount Lofty forests — doubly dependent on old trees and seed-bearing shrubs a tidied, fragmenting forest is running short of, and sliding as both disappear.

Plants

Banksia

A hard-leaved shrub that banks its seed in woody cones only a fire will open, and spends the interest on nectar for the region's honeyeaters — the drought-and-fire bargain in one plant.

Grasstree (Xanthorrhoea)

A blackened, spear-topped tuft that looks half-dead most of its life and is in fact one of the toughest things in the bush — it shrugs off flame behind a skirt of its own old leaves, then answers the fire with a flowering spike.

Grey mangrove

South Australia's only mangrove, holding on at the cold southern edge of a fundamentally tropical way of life — excluding salt at the root, sweating it from the leaf, and breathing through a bed of mud-top snorkels.

Messmate & brown stringybark

The two shaggy-barked eucalypts that roof the Mount Lofty forests — outliers cut off from their wetter south-eastern kin, holding a hotter, drier niche than their relatives will tolerate.

Mistletoe

The much-maligned parasite of the gum trees, planted branch by branch by its own dedicated bird — and generous enough, in flower and fruit, to feed and shelter a startling share of the bush's animal life.

Orchids and their fungi

A native ground orchid's seed is a mote of dust with no food reserve at all — it cannot become a seedling until it is found underground by one particular fungus, which is why you cannot rescue an orchid with seed alone.

Posidonia seagrass

The gulf floor's slow-growing meadow-builder — a true flowering plant, not a weed, that nurseries the gulf's seafood and buries carbon in the dark, and is easily lost to murky water and slow to win back.

River red gum

The great gum that lines every creek and river on the plains — a hollow-factory for wildlife, and the plainest living sign of where reliable water actually runs in a summer-drought country.

Samphire (glasswort)

The jointed, leafless little glasswort that drinks the sea and stores the salt in its own flesh — the plant that names the coast, and flushes it red at the height of summer.

South Australian blue gum

A big, wide-crowned gum, scattered now across paddock and street rather than standing in the grassy woodland it once dominated — and, in winter, one of the range front's few working nectar sources for the birds that pollinate it.

Spear-grass & wallaby-grass

The tussock grasses that once floored the whole of the Adelaide Plains under scattered gums — now the most vanished habitat in the book, surviving as less than one per cent of its former self in scattered fenced scraps.

Spinifex (Triodia)

A spiky hummock grass that takes about fifteen years after fire to grow back thick enough to shelter anything — the slow, unglamorous clock the mallee's most fire-sensitive animals live and die by.

The mallee eucalypts

A gum tree that gave up on being a tree — a dozen or more thin stems sprung from one massive buried lignotuber, the visible record of a plant that has burned and resprouted for longer than anyone has been counting.

Wattles (Acacia)

A fast, hard-seeded coloniser that pays ants in fat to bury its seed and then leaves fire, not the calendar, to decide when that seed wakes up — a cornerstone of the region's ant-sown flora.

Mammals

Brush-tailed bettong (woylie)

A rabbit-sized digging kangaroo that once tilled the Adelaide Hills every night, sowing truffle-fungus spores as it went — gone from the whole mainland but for a handful of fenced sanctuaries, one lost gear in the underground loop.

Common brushtail possum

The thump and scrabble overhead at dusk, the harsh rasping growl from the fig tree — a hollow-denning marsupial generalist that simply moved into the roof cavity when the woodland came down, and is now most of the 'nature' an Adelaide child ever meets.

Greater bilby (the lost suburbanite)

The long-eared burrower that once out-numbered rabbits in trappers' snares at the edge of Adelaide, and is now extinct across the whole settled south — the sharpest single case of reading absence.

Short-beaked echidna

A spine-covered, egg-laying insectivore from the oldest surviving branch of the mammal family tree — and one of the very few native mammals recorded the whole length of the gulf-to-range gradient, coastal scrub to summit forest to rain-shadow mallee, through two centuries of clearing besides.

Southern brown bandicoot (the last of the dynasty)

The last surviving member of the whole bandicoot-and-bilby family left in the Mount Lofty Ranges — a rabbit-sized digger holding on in a few wetter, scrubbier reserves, kept there only by ongoing fox control.

Western grey kangaroo

The big grazing marsupial of the Mount Lofty reserves and paddock edges — one of the few large natives the clearing and the foxes never managed to erase.

In the sea

Leafy seadragon

A seahorse relative dressed as a scrap of drifting weed, found nowhere on Earth but the cool southern-Australian seas — South Australia's marine emblem, and a slow, improbable life lived inside the gulf's seagrass meadows.

Frogs, fish & insects

The seed-planting ants

Meat ants and their smaller, less conspicuous kin hire out as gardeners for a fatty snack — hauling seed underground, eating the bribe, and leaving the seed itself planted and safe.

Through the year — the same country, season by season

Autumn — the break

March to May, the hinge of Adelaide's year — the killing summer heat eases, the subtropical ridge slides back off the continent, and the country waits, not always patiently, for the first rain that answers a five-month drought.

Spring — the flowering

September to November, the ranges run their busiest machinery of the year at once — pea-flowers and ground orchids blooming, honeyeaters breeding on the nectar, ants banking next year's seed — before the summer tap shuts off.

Summer — the dry

December to February, the tap shut and the ridge locked overhead — the season every plant and animal in the Adelaide region is built around surviving, and the one the fire trucks are built around too.
