What is the Jillaga Ash tree?

The Jillaga Ash (Eucalyptus stenostoma) is an endangered tree species found only in Wadbilliga and Deua National Parks in New South Wales, Australia.

How did botanists rescue the Jillaga Ash?

Two horticulturists, Amy Downie and Ollie Sherlock, abseiled down a 300-meter cliff in Wadbilliga National Park to collect seeds from four Jillaga Ash trees located 90 meters down the cliff face.

Why is the Jillaga Ash important to conserve?

The Jillaga Ash is a threatened species, with its population severely impacted by the 2019-2020 bushfires in Australia. The collected seeds will be used to grow seedlings and establish backup populations, preventing the tree from going extinct.

Botanists Abseil Down 300m Cliff to Rescue Endangered Eucalyptus Tree

On November 1st, 2025, two horticulturists undertook a perilous mission to save an endangered tree species in Wadbilliga National Park, New South Wales. Threatened flora ecologist Stan Wawrzyczek had spotted an Eucalyptus stenostoma, commonly known as the Jillaga Ash, growing 90 meters down a 300-meter cliff face.

Coincidentally, Royal Botanic Gardens Victoria horticulturist Amy Downie was an experienced abseiler, having cared for the RBGV's Grey Garden with hard-to-reach plants. Downie, along with her colleague Ollie Sherlock, a rock climber and acting team leader for natural systems, descended the uncharted cliff to collect gumnuts from four Jillaga Ash trees.
