Grampians Globe-Pea: A Critical Rescue Mission in the Face of Climate Change
The Grampians globe-pea, a critically endangered wiry shrub known for its vibrant orange and yellow flowers, was in full fruit when the recent fires swept through the Grampians National Park in western Victoria. The fire-ravaged the area, including 76,000 hectares that are home to this and other rare plant species.
Finding the globe-pea will be a top priority for a rescue mission led by the Royal Botanic Gardens Victoria (RBGV), which aims to identify survivors and document any signs of life in the burned landscape. The RBGV director and chief executive, Chris Russell, stresses the urgency of creating backup populations of species before they disappear forever.
“We do not yet know the extent of the damage,” Russell says. “But the work is critical, especially given the increasing frequency of severe bushfires driven by climate change.”
Collaborative Efforts to Save Rare Species
In collaboration with Victoria’s environment department and local community groups, RBGV is intensifying its conservation efforts in the Grampians, a biodiverse region also known as Gariwerd to Indigenous peoples. The national park is home to roughly a third of Victoria’s flora, including 49 unique plant species found nowhere else in the world.
When conditions improve, a team of botanists and horticulturalists will evaluate the damage and collect seeds and cuttings from threatened species. These will be stored in the Victorian Conservation Seedbank and in RBGV’s living collections.
“It’s such a diverse geological and environmental space,” Russell says. “There’s a high proportion of plants that are endemic to the Grampians, many of which are rare and threatened.”
Fire’s Impact and Adaptation Strategies
Fire can be both a driver and a threat to plant diversity. While some plants have evolved strategies to survive and thrive after a fire, such as resprouting from their trunks or germinating from dormant seeds, the frequency and intensity of recent fires are challenging their adaptability.
Dr Ella Plumanns Pouton, who researches the influence of fire on biodiversity, notes that a string of major blazes in 2006, 2013, 2014, and 2024 burned 90% of the Grampians landscape. “The issue is that plants need time to accumulate seed and recover,” she says. “Without that, even fire-adapted species could be lost.”
Climate Change and Conservation
According to Prof Angela Moles, a plant ecologist from the University of New South Wales, plants and their environments are undergoing rapid changes due to climate change. “We have hundreds, maybe thousands, of species that exist in just a few square kilometers,” Moles says. “Two fires too close together, and they can be gone.”
Seedbanks, once considered a futuristic idea, are now a critical part of conservation strategies. After the 2019-20 black summer fires, RBGV collected 105 threatened species from the fire scar, preserving 72 in seed form and 33 as cuttings for living collections.
Russell emphasizes the importance of these efforts: “We’re talking about plants where there’s just so little genetic material left on the planet that it’s an absolute treasure – what you’re handling is gold.”
Priority Species for Conservation
The Grampians globe-pea is one of five priority species, each facing unique threats. Others include the Mt Cassell grevillea, a small shrub with red flowers; the vulnerable Grampians rice-flower; the yellow-flowering Grampians bitter-pea; and the endangered Pomonal leek orchid.
“The团队 is physically demanding and sometimes hazardous work,” Russell says. “But everyone is passionate about playing an active role in preserving these beautiful and endemic plants.”

Challenges and Solutions
Dr Tom Fairman, a forest and fire scientist from the University of Melbourne, notes that climate change is complicating conservation efforts. “Even relatively common, fire-adapted species can struggle when intervals between fires are too short,” Fairman says.
Plumanns Pouton suggests new solutions, such as creative ways to protect plant populations and reduce fire risk, as well as establishing insurance populations. These strategies can help ensure the survival of rare species in the face of an uncertain future.
The rescue mission in the Grampians is a testament to the dedication of conservationists. With ongoing efforts and support, these species can have a fighting chance at survival in the face of climate change.
