This is country that swings between extremes, and the people who knew it best learned to swing with it. For the Aboriginal people of the region, the diverse climate of Lochern was not a hardship but a resource - they learned to use the dry spells and the wet, adapting to the seasonal transformation of the land and reaping its bounties as they came. When the floods arrived, the plains exploded with growth and the waterholes filled. When they retreated, the country pulled back into its lean, dry self. Survival here was never about fighting the seasons. It was about reading them, and Lochern's earliest custodians read them with a precision that European newcomers would take generations to approach.

Lochern protects an undisturbed cross-section of the Mitchell Grass Downs, and it does so completely - the park is home to all four species of Mitchell grass, the tough tussock grasses that have fed both native wildlife and grazing stock across inland Australia. This is the silver-grey, sun-bleached plains country that defines so much of the outback's interior, grass that looks dead in the dry and surges back to life with rain. That the park holds the full set of these grasses, in undisturbed condition, is exactly why it was set aside. It is a working reference library of the Channel Country's grasslands, kept intact while so much surrounding land was given over to stock.

The eastern parts of the park are laced with the channels of the Thomson, and it is here that Lochern comes alive. Several lagoons and waterholes hold water long after the surrounding plains have dried, becoming vital refuges for birds and other wildlife in a thirsty landscape. Major Mitchell's cockatoos flash pink and white over the channels; red-tailed black-cockatoos and Bourke's parrots work the timber along the water. For wildlife in an arid region, a permanent waterhole is not a luxury but a lifeline, and Lochern's wetlands draw life from across the surrounding country the way a campfire draws people on a cold night.

Lochern was a grazing property before it was a park - one of a series of western Queensland stations that the state acquired and converted to conservation. It was established as a national park in 1994 and later enlarged, in 2004 and again in 2008, growing into the reserve it is today. The pastoralists who worked it left their own marks on the land, including the dams they built to harvest rainwater across the run. That layered history is part of the park's character: a place that carried stock for generations and now carries something else, an undisturbed remnant of the Channel Country held in trust for the birds, the kangaroos, and anyone willing to make the long drive west.
