Susan Downes walked into the hallway of an old farmhouse for sale near York, Western Australia, and knew instantly: "Oh, this is my house." The catch was the 200 hectares that came with it.

  • 120 hectares of the farm now restored
  • 45,000 native seedlings planted since the project began
  • 45 plant species that returned on their own from the dormant seed bank
  • 80+ volunteers who turn out for planting and seed-collecting days

Downes, a widowed retired general practitioner then in her 60s, had pictured a modest cottage with "a little bit of garden." Instead she found Mount Mackie, a 295-metre hill on the property where ancient York gums and wandoo trees had somehow survived roughly 150 years of grazing, their understorey stripped bare beneath them. Almost all that remained were "these magnificent old trees," standing alone over bare, compacted paddock. "I felt a great connection to the land," she says. She bought the farm anyway, with no real plan beyond knowing she couldn't walk away from it.

From Grazing Paddock to Gum Woodland

Downes, who trained as a botanist before switching to medicine, started small: a local grant to control foxes and feral cats. Then came a grant for 24,000 trees over three years. "I thought, OK, I can start doing this," she says. "This is what I really want to do."

Today, now 76, she spends her days rebaiting traps, weeding and planting — plus what she wryly calls "all this bloody admin." The restoration now spans 120 hectares of her working farm, supported by Friends of Mt Mackie, a volunteer group with a core crew of about eight and more than 80 others who join organized days. Forty-five plant species have reappeared on their own, germinating from seed that had lain dormant in the soil for decades.

"Some of the trees are now taller than I am," Downes told The Guardian. "You can see them from two or three kilometres away."

A Covenant That Outlives Her

Downes is placing the restored land under a permanent conservation covenant, a legal protection meaning it can never be cleared again, regardless of who owns the farm next. She is far from alone: Australian Bureau of Statistics data cited by the Guardian suggests roughly 290,000 Australians volunteer with environmental or animal welfare groups, and in Landcare Australia's 2026 national survey, 80% of respondents were aged 55 or over.

Peter Garrett, Landcare Australia's chair, calls older Australians "the backbone" of the movement. Retirement, he says, brings time but also a chance to think about what gets left behind for grandchildren.

"The sort of stirring song of the Australian bush calls to them."

Downes isn't an outlier so much as part of a quiet trend. Across the country, retirees are channeling decades of spare capacity into the landscapes around them: a Gold Coast woman who spent a career in the cheese industry now monitors sea slugs at Burleigh Heads; others count water bugs, turtles and native plants in council reserves and national parks. None of it makes headlines on its own, but added together it is reshaping how Australia manages land it can no longer afford to simply let degrade.

In a world of problems that can feel too big to touch, Garrett says conservation offers something a person can actually finish: "our back yard, our bit of bush down in the gully, our creeks and streams." For Downes, that "bit of bush" is now a 120-hectare woodland that will outlast her — a working farm turned living legacy, one seedling and one dormant seed at a time. The trees she planted as saplings are now taller than she is, visible from kilometres away, and still growing.
