As the shot-hole borer continues to spread across Perth, calls grow for alternative method to cutting established trees (14 Oct 2024)
Article summary: Western Australia's ongoing battle with the shot-hole borer beetle is prompting discussions about moving beyond the current eradication strategy, which focuses on cutting down infected trees. Since the beetle was first detected in Fremantle in 2021, over 3,600 trees in Perth have been felled, but the infestation persists. The beetle, native to South-East Asia, kills trees by blocking water and nutrient flow. Experts are questioning how many trees must be lost before alternative methods are considered, especially since the approach has not stopped the beetle's spread.
Independent MP Kate Chaney has raised concerns in Parliament (see related video below) about the sustainability and effectiveness of the eradication efforts, urging for the $44 million in funding to be used wisely. She emphasised the need for research into new strategies, given that no other country has successfully eradicated this beetle. Arborist Tom Robinson is among those trialling alternative approaches, including pesticide use. He advocates for an integrated pest management strategy, recognising that complete eradication may not be feasible.
