Perilous Pursuit of Preserving Endangered Species: Abseiling Horticulturists Save Gumnuts from Cliff Face.
In a daring feat of horticultural heroism, two abseiling experts - rock climber and team leader Ollie Sherlock and Royal Botanic Gardens Victoria (RBGV) horticulturist Amy Downie - embarked on an arduous 5-day expedition to rescue gumnuts from a critically endangered tree situated precariously 90m down a 300m cliff face in Wadbilliga national park, New South Wales.
Amy Downie, skilled at navigating hard-to-reach plants in RBGV's Grey Garden, was roped in for her expertise in abseiling. Her colleague Ollie Sherlock added his prowess as a rock climber and team leader to the mix. The duo formed an unbeatable team to tackle one of Australia's most inaccessible environments.
With steep slopes, rocky hilltops, and shallow soils characteristic of the Jillaga Ash tree - also known as Eucalyptus stenostoma (Jillaga Ash) - Downie noted that "the abseiling site had never been descended before." Their resourcefulness was on full display when they tied two ropes together to extend their reach.
Utilizing a pole pruner, the duo carefully collected gumnuts from four trees. The collected samples will be used to grow seedlings in an effort to boost populations and save the Jillaga Ash tree from extinction. Additionally, cuttings will be stored and dried for future generations.
A recent threat to the Wadbilliga population - nearly destroyed during the black summer bushfires - highlights the urgency of this mission. The Jillaga Ash tree can live up to 400 years but lacks post-fire regeneration capabilities. It usually thrives on steep slopes, rocky hilltops, and ridgelines with limited soil depth.
The New South Wales government has funded the Threatened Species Conservancy's efforts to save six species in the region, including the critically endangered Jillaga Ash tree.
In the aftermath of this daring rescue mission, Downie expressed interest in exploring new locations where abseiling can be utilized for future plant rescues. Ollie Sherlock added that their experience underscored the potential benefits and challenges associated with utilizing drones to identify plants and assess risks before retrieval.
The RBGV's state botanical collection now holds more than 1.5m specimens, including the rescued Jillaga Ash seeds, ensuring a safer haven for these endangered species in the future.
