A recent bushfire has tragically destroyed a considerable portion of the habitat essential for the critically endangered western ground parrot, also known as kyorling in the Nyungar language, along the south coast of Western Australia. According to the Department of Biodiversity, Conservation and Attractions (DBCA), this loss represents a significant threat to a species that has already seen its numbers dwindle to an alarming estimate of just 150 individuals remaining in the wild.
The decline of the western ground parrot is attributed to various factors, including habitat destruction, predation from invasive species like feral cats and foxes, increasing wildfire occurrences, and reduced rainfall. Currently, the last viable wild population is confined to a narrow stretch within Cape Arid National Park and the adjacent Nuytsland Nature Reserve, situated about 100 kilometers east of Esperance.
During the previous weekend, a bushfire, ignited by lightning, rushed through this national park before firefighters successfully contained it. The extent of the damage is still being assessed by the DBCA. Regional ecologist Sarah Comer reported that roughly 11,000 hectares of critical kyorling habitat were lost, with initial estimates suggesting that around 30 percent of their core habitat was affected. "We need to conduct extensive monitoring post-fire to verify these figures," she stated.
This incident marks yet another severe bushfire incident threatening the already vulnerable kyorling population. Dr. Comer emphasized the importance of having robust fire response and mitigation strategies due to the area's high susceptibility to lightning-induced fires. "This recent fire showcases our department's ability to quickly mobilize firefighting resources," she noted. "While the damage could have been worse, losing such a significant area is still concerning."
Of particular worry is the timing of this fire, which coincided with the breeding season when the parrot parents are caring for their fledgling chicks. "Though these birds are capable fliers, it's likely that the adult birds would stay close to their young during such crises," Dr. Comer explained. There remains uncertainty about whether the fledglings were mature enough to escape the flames. "We’re hopeful that many managed to find safety, but we need to confirm that," she added.
Monitoring the kyorling population presents unique challenges, as they can only be tracked using acoustic devices to listen for their calls during their movements between feeding and roosting grounds at dawn and dusk. Unfortunately, it is believed that six of these crucial monitoring devices were destroyed in the fire. Despite these difficulties, Dr. Comer mentioned that the population of kyorlings over the past decade has remained relatively stable. "What we haven't witnessed is the dramatic declines seen in other areas over the last 25 years where they have disappeared, which is encouraging," she remarked.
In addition to the wild populations remaining in Cape Arid and Nuytsland, Dr. Comer highlighted that efforts such as translocating wild birds to create new populations, along with a captive breeding program at Perth Zoo, are fostering hope for the future of this species. "It’s about exploring diverse conservation options to ensure the survival of kyorlings," she said.
Adding to the optimism, Perth Zoo’s captive breeding initiative has recently achieved a remarkable milestone: the successful hatching of a fully fledged western ground parrot chick, marking a world first. Matt Ricci, the Australian fauna supervisor at the zoo, expressed excitement over the development, stating, "The little chick is doing exceptionally well. Each day we witness its growth reminds us of how incredible this achievement is, given that it’s a world first."
Mr. Ricci stressed the critical role of captive breeding in safeguarding the future of the kyorling, especially as Cape Arid faces an escalating threat from bushfires. "We are likely to see more extreme weather events, particularly during the summer months," he noted. The team at the zoo is also looking to replicate its success with the western ground parrot in breeding other endangered species, such as the dibbler. "Our mission at Perth Zoo is to facilitate breeding in captivity so we can bolster wild populations," Mr. Ricci explained. "For the ground parrot, I anticipate similar successful outcomes in the future."
But here's where it gets controversial: Are enough measures being taken to protect these vulnerable species, or are we merely reacting to disasters instead of proactively preventing them?
